The D-inputs of the triggers, 17, 20, 23, 26, 34, 35, 49 and 66 are consistently level 1, The operation of the time interval meter is based on the interpolation method Uj providing high measurement accuracy in a wide dynamic-input unit 13 of the registration-indicative range, in which time, the thirteenth output unit 14 "oh interval tj ,, limited start and stop pulses , imeet- with roughly (where N is the number control is the output element AND 82. The device works as follows. sequential counting, and time intervals tg (tp) between the starting (stop) pulse and the subsequent counting. In the initial state, the binary-decimal counters 11 and 10 accurately measure the starting (capacitance K) and Om impulse with the help of a conversion ( the capacitance of the CC) of the channels of the time scale adjuster of the BAB type. the binary-decimal error of the interpolation measure- ment counter 2 of the rough measurement of the capacity of the transducer interval of the conditional condition (7 state 9 ... 9997. Wired by the multiplicative and additive switches 74-76 are in the normal range The occurrence of a multiply closed state. Triggers 15, the catemental component associated with not-17,20,23 and 26 of calibration block 4 by the ratio of the actual value of the coefficient (Fig. 2) are set to the conversion factor segments of the dead state. In blocks 5 and 6 of the unit t (tp) of the block and Because of the inaccuracy of the triggers of ambiguity (Fig. 3), the triggers 30 and 31, 34 and 35 are held in the initial setting or, as a result of the closed state, the elements AND-HE 32 that act destabilizing factors, and 33, 36 and 37, respectively. In blockers, the appearance of an additive composition of 7–7 and 8 interpolations (FIG. 4) triggers due to delays during the passage of 41 is set to the zero state. -NOT 38 and 42 are closed, zero themselves, as well as counting pulses, the potential flowing through the locks the purpose of reducing multiplicative contacts is on switch 74 and. 75 component error in the measurement- (Fig. 7). Triggers 46 and 49 of block 9, a time slot user is entered. The boxes (Fig. 5) keep the AND-NE elements 47 and 52 in the closed state. The zero potentials supplied from the switches 74 and 75 (Fig. 7) through the thirteenth to fourteenth and tenth to eleventh contacts, respectively, element is NOT-59 f5 -, 0 In the calibration calibration block 12 (fig. 6), the trigger 66 holds the AND-NE element 67 in the closed state. The zero potentials applied from the switches 75 and 76 through the first and second and tenth and eleventh contacts (Fig. 7), the elements AND 69 and AND-NOT 65, respectively, are closed, and the AND-NE 78 element is opened through the NOT element 77 (FIG. 7). The D-inputs of the triggers, 17, 20, 23, 26, 34, 35, 49 and 66 are consistently level 1, 35 counting pulses on the time interval tjj, Au is the period of the following counting pulses) using the method sequential counting, and the time intervals tg (tp) between the start (stop) pulse and the subsequent counting .m pulse - with the help of a BAB type time scale converter. The error of the interpolation gauge of the interval intervals is due to the multiplicative and additive components. The appearance of the multiplicative component is due to the inequality of the real value of the coefficient 91307443 conversion factor calibration. For this, in the calibration mode of the conversion coefficient, a reference time interval is applied equal to my ne right TD, which is generated by coefficient calibration blocks 4. The calibration mode of the conversion coefficient of the interpolation block 7 of the start channel (Fig. 8). Calibration mode containing two cycles is provided by pressing the button of the switch 75 Calibration Kg (Fig. 7). At that, counter 2 is set to the state 9 ... 97, and counters 10.11 and 68 - to the state O, through closed fifth and the sixth contacts of the switch 75, the O level is applied to the elements AND-NOT 91 and 72 of the control unit 14, prohibiting the passage of the starting and stop pulses 5 through them through the closed eighth and ninth contacts to the block 7 (8) interpolation to the elements AND- HE 38 and 42 (FIG. 4) are fed level 1. In block 9 of addition (FIG. 5), the element NOT 56 is closed through eleventh and twelfth switch contacts 75 (FIG. 7) is applied level T. Through the closed second and third contacts, the level 77 of the control unit 14 is applied to the level In the first calibration cycle of the conversion coefficient, pressing the switch button 90 Start (without latching) at the output of the flip-flop 89 (Fig. 7) appears a positive voltage drop Uj, after which the pulse shaper 83 generates a negative pulse U the duration T attached to the drop The 0/1 signal goes through the AND 82 element as a pulse Uj of the initial installation of the device to its initial state in all the blocks of the device. (nala and The pulse from the output of the generator 83, delayed by the delay line 84 by a value greater than 4 C (, 5 as a pulse of the calibration start U enters the coefficient calibration block 4 to the single input of the trigger 15 (FIG. 2). With the arrival of the pulse U, the trigger 15 is set to a single state (Uy) that permits the passage of the counting pulses Ug from generator 1 through the element I-NOT 16. As a result of them: the pulse U is asynchronous with the counting pulses and can come, at any time, at the output of the element AND-NOT 16 ten there may be ambiguity, i.e. The first of the counting pulses that passes through the NAND 16 (U) element may have an amplitude or duration insufficient to trigger subsequent devices. Therefore, the first counting impulse (U) that passed through the element AND-NOT 16 of negative polarity enters the countable input D-type trigger 17 by 0/1 difference, sets it to one state, and zero potential from the inverse output of the trigger closes the AND-NE element 16, while the unit potential from the direct output (Ug) opens an AND-HE 18 element. As a result, an impulse passes through the output of the AND-HE 18 element. The duration and amplitude of which do not depend on the arrival phase of the pulse U, From the output code of the AND-NE element 18, a pulse U is fed to the driver 9 and to the counting input of a D-type flip-flop 20, as a result of which the flip-flop is thrown over a 0/1 drop of the UQ signal, closing the AND-HE element 18, P-pulse and,. (, from the output of the imager 9. which is the beginning of the time; -5 times the interval t, is fed into the interpolation block 7 (8) to the AND-NE element 42, (Fig. 4). Besides; the impulse Uj is a chellesa element HE 2 on the counting input of the trigger 22 (U), and depending on the initial state of the trigger 22, a voltage drop U ,,., J ,,,, appears in the forward and inverse outputs as a result, one of the B-type triggers 23 and 26 switches to the one state. When the trigger 23 is switched, the signal (differential 1/0) from its injector output is delayed by the delay line 24 relative to the differential 1 / O signal U, Q by no more than 2 and not less than 1.5 s. From the output 24 of the line holding signal 25 U. , 5 through the element AND-NOT knocks on the element AND 27 () and opens it on. As a result, the counting pulses (llfj) begin to pass through the AND 27 element. The first of the counting pulses passed is the end of the time interval t, which enters the interpolation block 7 (8) at the input of the AND-38 element, so it is supported the formation of the time interval 6,, Impulse: the beginning and the end of the time interval b (and, -,, U., 7 pass through the open elements AND-HE 42 and 38 (Fig. 4) and the elements AND eleven 40 and 39, respectively, to the single and zero inputs trigger 41, the Formed time interval t from the trigger output 41 U, q (U) goes to the converter 43 of block 7, which provides an increase in K times the length of time interval t. From the output of the converter 43 of block 7, a pulse of duration KtU ,, () goes to the second (third) input of block 9 of addition (Fig. 5). Pulse u2 from the output of converter 43 of block 7 opens element I-HE 58, allowing the passage of counting pulses Ug from generator 1 through element I-NE 58 () and element 57 (Uj) to counter 11 of the accurate measurement of the starting channel. At the same time, the number of pulses N Kt / 6 Q on the interval Kt is recorded by a counter 11 with a capacitance K of pulses. As a result, in this mode, the number of counting pulses corresponding to the duration of the time channel t converted in the converter 43 of the block 7 of the starting channel passes to the input of the counter 11. A pulse from the output of converter 7 of block 7 opens element 61 (Ujj), allowing the passage of counting pulses Ug from generator 1 through element HE 60 and element 54 (Uj ,.) into the counter 10 of the exact measurement of the stop channel. In addition, from the output of the converter 43 of the block 8, a pulse 1/22 enters the shaper 45 J, forming a pulse with a duration tied to the trailing edge of the pulse U, from the output 25 of those in the first cycle (,,), except that of the flip-flops 23 and 26, the flip-flop is switched without switching in the first loop (Ujo). When the flip-flop is switched 26 30, the signal U, g from its inverse output through the element AND-NOT 25 enters the input of the element AND 27 (U, g), opening it. As a result, through the element And 27 begin to pass counting pulses 35 And the pulses of the beginning and end of the time interval (U, o and U, -,) pass through the open elements AND-NOT 42 and 38, and the elements 40 and 39 (Fig. 4), respectively, on the trigger 41 of which is fed to the single input 40 Opening the time interval trigger 46. As a result, the trigger 46 switches (), the AND-NOT 47 element is opened, At the same time (in the absence of a ban, NOT 48,  ABOUT which enters the converter, 43. The converter provides an increase in K times the length of the segment C of its output pulse duration t-- taking place during the action of K (t-co) and (), pulse Uj enters,) the passage of counting pulses through the IS-NE 4.7 element (U, (j) to the counting input of the D-type flip-flop 49 and through the element is NOT 50 on the ale unit 9 of the addition (Fig. 5). The impulse from the output of the converter 43 of the block 7 opens the element AND-NOT 58, allowing the passage of the counting names AND-NOT 52 (). Trigger 49 re-50 pulses U through the element AND-NOT 58 switches (Uj,) 0/1 difference - per- (Uj,) and AND 57 (U) to counter 11. Ugg passed counting pulse Ugg, permitting the passage of pulses through the element AND NOT 52 (U) and the element And 54 () in the counter 10 with the capacitance ZK it is sosiruyus the counter 1 1 with the capacity K and before it is completely filled. After this is the pulse. As a result, in this mode th overflow pulse from counter to counter input 1I chica 10 sets up the triggers 46 and 49 to zero state prohibiting The number of pulses N./j; K (t-C.) / C. on the interval K (t-, ficaprococyte, the number of countable pulses, corresponding to the duration of further passage of the counting pulses through the AND-NOT elements 47 and 52. In addition, the overflow pulse enters the control unit 14 (FIG. 7) on the delay line 79, from which the pulse delays and passes through the element I-NE 80 (.) And starts the one-shot.86, which forms a pulse of duration (s). From the output of the one-vibrator .86, the pulse enters the registration-display unit 13 and provides a census of the measurement result of the time interval from counters 2 and 11 to the display registers. In the second calibration cycle of the conversion ratio with the push of the switch button 90 start (Fig. 7) the initial installation of all elements of the meter is carried out as described for the first cycle. The operation of block 4 (Fig. 2) during the second cycle is similar to the operation in the first cycle (,,), except that of the flip-flops 23 and 26, the flip-flop is switched without switching in the first loop (Ujo). When the flip-flop is switched 26 the signal U, g from its inverse output through the element AND-NOT 25 enters the input of the element AND 27 (U, g), opening it. As a result, through the element And 27 begin to pass counting pulses    And the pulses of the beginning and end of the time interval (U, o and U, -,) pass through the open elements AND-NOT 42 and 38, and the elements 40 and 39 (Fig. 4), respectively, on the trigger 41 form O which enters the converter, 43. The converter provides an increase in K times the length of the segment C of its output pulse duration t-- The number of pulses N./j; K (t-C.) / C. on the interval K (t-, fixed input of the counter 1I Prochocyte number of counts of pulses, corresponding to the duration of the time channel t-og converted in the converter 43 of the starting channel. A pulse and, 2 from the output of the converter 43 of the block 8, opens the element 61 (Ujg-), allowing the passage of the counting pulses U from the generator ) through the elements 60 and 54 () into the counter 10 of an accurate measurement of the stop channel. In addition, from the output of the converter 43 of the block 8, a pulse U ,, goes to the shaper 45, which forms an imgulse and a duration vT, tied to the trailing edge by it pulse 3 from the output of which is delivered to a single input of trigger 46. As a result, trigger 46 switches (Ujg), opening the AND-NOT element 47. At the same time (in the absence of a ban, NO 48 that occurs during the pulse ( and,) - starts the passage of counting pulses through the element AND-NE 47 (Uj) to the counting input of the trigger 49 of the D-type and through the element NOT 50 to the gold AND-NOT 52 () - The trigger 49 switches (u5) to the differential 0 / 1 - the first transmitted impulse (counting) 5 permitting - the passage of pulses Ujo through the elements AND-NOT 52 (U) and the element AND 54 (s counter 10 the capacitance of the safety device until it is completely filled. Next, the overflow pulse Llgj with this, th counter sets the triggers 46 and 49 to the zero state, prohibiting the further passage of the counting pulses through the elements AND NOT 47 and 52. In addition, an overflow pulse enters control unit 14 (Fig. 7) to the delay line 79, from the output of which the pulse and 5 delayed by Wjd, passes through the IS-NE 80 (Ujj) element and starts the one-oscillator 86, forming a pulse of duration 5 (o (out of 5) -. From the output of the single-oscillator 86, the pulse arrives at the registration-display unit 15 and provides a census of the measurement result of the time interval t-co from counters 2 and 11 into the display registers. Moreover, if the difference in the results of the time interval conversion in the first cycle t and in the second cycle t-S Q is different from the value of tTg, the conversion coefficient is adjusted using a resistor in the converter 7 of block 7. 744314 After the calibration of the conversion coefficient of the start channel is completed, the switch 75 returns to its original position and the conversion coefficient of the stop channel interpolation unit 8 is calibrated. Calibration mode conversion mode block 8 interpolation of the stop channel (Fig. 8). Sharp security10 It is detected by pressing the switch 74 button Calibrating K- (FIG. 7). At the same time, through the closed fifth and sixth contacts of the switch 74, level O on the elements AND-NOT 91 and 71, prohibiting the passage through them of the stationary and stop pulses, through the closed eighth and ninth contacts in block 8 (7) of the interpolation on the elements IS-HE 38 and 42 (FIG. 4) Level 1 is supplied. In addition unit 9 (FIG. 5), level 56 is supplied to element NOT 56 through closed eleventh and twelfth contacts of switch 74. Through closed second and third contacts to element HE 77 of control unit 14 (FIG. 7) and element 69 of calibration block 65 zero (Fig. 6) is supplied with a level, level O is fed through closed fourteenth and n umpteenth contacts of switch 74 (FIG. 7) in the adding unit 9 (FIG. 5) to inhibit the passage of an element countable -lmiupsoB AND-NOT 58. 40 45 In the first cycle of the calibration of the transform coefficient, pressing the switch button 90 Pz ck at the output of the trigger 89 (Fig. 7) appears a positive voltage drop U, -, after which the pulse shaper 83 generates a negative pulse and a duration of 2 o, | Zanny to the differential 0/1 signal iJ, which comes through the element And 82 from the quality of the initial installation pulse to the initial state of the device Uj in all blocks of the device. The impulse U from the output Q and the driver 83, delayed by the delay line 84 by 4 t-, as a pulse of the beginning of the calibration U, enters the calibration unit 4 (3) test coefficient (Fig. 2). The operation of unit 4 in the mode of calibration of the coefficient of conversion of the stopping of block 8 first channel and in the second cycle is similar to the operation of this block in the coefficient calibration mode transformations of the interpolation block 7 of the start channel. (). Jam pulses of the beginning and end of the time interval t (U, jj and -J) pass through the open elements IS-HE 42 and 38 (Fig. 4) and elements AND 40 and 39, respectively, to the single and zero inputs of the trigger 41. Formed time interval t from the output of the flip-flop 41 1 (U (cj) is lengthened by the converter 43 by K times and fed to the adding unit 9 (Fig. 5). From the output of the converter 43, the pulse Uj2 with the duration Kt opens element 61 ()) the passage of counting pulses Ug from the generator 1 through the open elements AND-NOT 59 and 57 into the meter 11 is an accurate measurement of the start channel (U). the number of pulses in the Kt interval is fixed by the counter I1. In the second calibration cycle of the conversion factor, the pulses of the beginning and end of the time interval Sh 15 20 zero calibration, providing a digital correction to the additive error component. In this mode, the Start Calibration inputs the same calibration pulse, which means measuring the time interval of zero duration. Zero calibration mode (Fig. 9 and 10). Figures 9 and 10 show the voltages at the outputs of the respective blocks. Switching on the mode is ensured by pressing the switch button 76 Calibration Kp (Fig. 7). In this case, the coefficient calibration unit 4 is connected via closed second and third contacts of the switch 76 and, through AND-HE elements 71, 9 and 73, 72 to blocks 5.7 and 6.8, respectively. Through the closed eleventh and twelfth contacts of the switch 76, an element IS-HE 69 of the zero calibration block 12 (Fig. 6) is fed level 1, Star .t- o (and, o, and „) pass through the open 25 stop pulses per element AND-HE elements 42 and 38 (Fig. 4) and Ele ™ ™ 7 and 73 are not supplied, since The cops 40 and 39 respectively to the inputs of the trigger 4. The formed time interval t-Tj, from the output of the trigger 41 (U,), is extended by the converter 43 K times and enters block 9 of addition (Fig. 5). With the output of the converter 43, a pulse of duration K (t-cr (j) is filled by counting impulses (ujj j and through open element AND NOT 59 and element AND 57 post drops in counter 11 (U); Wherein the number of pulses on the interval K ( recorded by counter II. As a result In this mode, the input of the counter is 0 pr U of U, after which the driver ka 11 passes only the number of counting pulses 5 corresponding to the duration of the time channel converted by the converter 43 of the stop channel. The result is displayed, and if the difference in the results of the time interval conversion in the first cycle t and in the second cycle t - i is produced. about is different from the value of t-,  about , 83 pulses forms a pulse 1}, which comes through the element And 82 as a pulse of the initial installation to the initial state Uj of the device in all the blocks of the device. In this case, the counter 2 is set to the state 9 ... 97, and the counters 10.1 (Fig. 1) and 68 (Fig. 6) are set to the state O, Impulse and, delayed by line 85, the tuning of the conversion factor on as an impulse nor by using a resistor (not shown) in converter 43. After the calibration is completed, the conversion rate of the stop channel is interleaved by overwriting the result of the zero calibration U37 Hfig. 9) enters the zero calibration block 12 at the counter 68 (FIG. 6), allowing the result coding 74 to return to the initial zero calibration condition in the measurement mode This is the zero calibration, The automatic time counter 11 is implemented in the time interval meter, and the IU pulse from the output of the shaper 83 (Fig. 7) is delayed by the delay line 84 by 4 t (, j as the calibration start pulse five 0 zero calibration, providing a digital correction to the additive error component. In this mode, the Start Calibration inputs the same calibration pulse, which means measuring the time interval of zero duration. Zero calibration mode (Fig. 9 and 10). Figures 9 and 10 show voltages at the outputs of the respective units. The inclusion of the mode is provided by pressing the button of the switch 76 Calibration Kp (Fig. 7). In this case, the coefficient calibration unit 4 is connected via closed second and third contacts of the switch 76 and, through AND-HE elements 71, 9 and 73, 72 to blocks 5.7 and 6.8, respectively. Through the closed eleventh and twelfth contacts of the switch 76, level I-HE 69 of the zero calibration unit 12 (Fig. 6) is fed level 1, Star the fourth and fifth, seventh and eighth contacts of the switch 76 (FIG. 7) are open. Level 1, coming through the closed eleventh and twelfth contacts, opens element AND 69 in the zero calibration block 12 (FIG. 6), allowing the pulse of the initial installation of the device to the binary-decimal meter 68 to pass With the push of a switch button 90, the start at the output of the trigger 89 (Fig. 7) appears to be a positive difference in the spun length U, after which the driver , 83 pulses forms a pulse 1}, which comes through the element And 82 as a pulse of the initial installation to the initial state Uj of the device in all the blocks of the device. In this case, the counter 2 is set to the state 9 ... 97, and the counters 10.1 (Fig. 1) and 68 (Fig. 6) are set to the O, Impulse state, and delayed by the record recording line 85 of the zero calibration result U37 Hfig. 9) enters the zero calibration block 12 at the counter 68 (Fig. 6), allowing the counter 11 to allow the result to be copied, and the IU pulse from the output .. of the former 83 (Fig. 7) delayed by the delay line 84 by 4 t (, j as the start pulse of the calibration U, 17 arrives at the second input of the coefficient calibration block A (FIG. 2). With the arrival of the pulse U, the trigger 15 is set to the unit state (Uj), allowing the passage of the counting pulses Ug from the generator 1 through the AND-NOT element 16. The first passing through the AND-NOT 16 element is the counting pulse (UY) with the falling edge sets trigger 17 a state in which the zero potential from the inverse trigger trigger closes the IS-NOT element 16, and the unit potential from the direct output (Ug) opens the IS-NOT element 18. From the output of the IS-NOT element 18, the pulse arrives at the driver 19 and at the counting trigger input 20, causing trigger triggering The closed element is AND-NOT 18. From the output of the former 19, the pulse U, p is inverted by the element HE 21 and, as a calibration pulse, zero U is fed to the control unit 14 (FIG. 7) through the closed second and third contacts of the switch 76 to the elements AND-NOT 71 and 73. From the outputs of the elements AND NOT 71 and 73, the zero calibration pulse passes through the open elements AND-NOT 91 and 72 to the second, third inputs to blocks 5.7 and 6.8, respectively. The arrival in these blocks of the same calibration pulse zero means that a zero time interval is applied to the input of the device. The arrival of the calibration pulse zero and “to the single input of the trigger 4 through the element 40 (Fig. 4) ensures the formation of the beginning of the time interval t3 (U, q), and to the single input of the trigger 30 (Fig. 3) the increase of the first counting momentum. Switching trigger .p 30 (Ujg) under the influence of a pulse and ,, calibration zero opens the element AND-NOT 32. The first of the counting pulses, following with a period) from generator 1, passed through the element AND-NOT 32 (U), switches the back edge of the trigger 34. At the same time, the IS-NOT 32 element is closed with the signal from the inverse output of the trigger 34, which makes it impossible for the further passage of counting pulses through it. The signal from the direct output of the trigger 34 (U4o) opens the element AND-NOT ment AND-NOT-36 (and. 3 (Fig. 1, and,) and the ele 1 1 allowing the passage through them of the counting pulses, respectively, to the first input of the counter ten f5 20 7443 J VJ ka 2 of coarse measurement (U,) and through the delay line 28 in interpolation block 7 (i) per element I 39. The first of the counting pulses passed; p; through the element And 39 on the R input of the trigger 41, finishes the formation of a time interval of duration tg. The generated time interval tg from the trigger 41 is supplied to the converter 43 (U ,, j), which provides an increase in K times the length of the time interval t. From the output of converter 43, a pulse with duration UL (and) opens element I-NE 58 in block 9 of addition (Fig. 5), allowing the passage of counting pulses from generator 1 through element I-NE 58 (and,.) And element AND 57 (tf) to the score 23 - Vg Chick 11 is an accurate measurement of the start channel. At the same time, the number of pulses in the Ktg interval is fixed by counter 1 with a capacitance K of the counter I1 owls In the case, a transfer pulse occurs, which is fed to the second input of the rough measurement counter 2, in which it is recorded. Similarly, with the arrival of a pulse, zeroing and, through the elements AND-HE 73 and, 72 (Fig. 7) to the single input of the trigger 31 (Fig. 3) and the single input of the trigger 41 through the element 40 (Fig. 4) the processes of allocating the time interval tp (U –U), except that switching the trigger 35 closes the AND-NE 3 element (U ((7). As a result, the counting pulses do not pass through the AND-NE element 3 to the first the input of counter 2, i.e., the measurement of the time interval t ends. The value of the delay time t, by lines 28 and 29 of delays, is selected from the condition Itoal t y. b, ,,, „„ it, t. but. g about the zlegg label) Y yes - the value of the additive error. A pulse of duration tp (U2 (,), generated by the trigger 41 (Fig. 4). Goes to the converter 43 of the block 8, where it is converted into a pulse the duration of Ktf (ll,). From its output, pulse U i enters block 9 of addition (FIG. 5) to shaper 45, and also permits the passage of counting pulses through AND 61 (Uj) and the element HE 60 on the element I 54 and further into the counter 10 of an accurate measurement of the stop channel (). The number of pulses N ip-Ktp / cp on the interval impulses, about Ktp is captured by a counter. Em 1913 bone ZK and 1pulsov. from the output of the impulse generator 45 and, (fig, 10) of duration p-t, assigned to the trailing edge of the impulse Ktp (U,), is fed to the single input of the trigger 46. At the end of the impulse Kt from the converter 43 of the block 7 through the element 48 the prohibition of the element AND-NOT 47 is lifted, at the end of the pulse Kt from the converter 43 of block 8 switches the trigger 46 (). at After graduation. addition of time intervals, i.e. at the moment of overflow of the counter 10, the overflow pulse () of this counter enters the control unit 14 (Fig. 7) on line 79. delay, the output of which as a result, the element opens NAND 47 and the addition of the number „„ t, impulse u, l, delayed by -3 o,. pulses corresponding to the segment. „P C element AND-NOT 80 ( vommeni kt. -3K-Kt. with impulse number ot and runs a one-shot ob, form. So .Ktg and Ktp 20 time Kt -3K-Ktp, with the number of pulses recorded in counter 1, corresponding to the length of time as the end of pulses not synchronized with the sequence of counting pulses, there may be ambiguity, which is eliminated due to the fact that the first of the counting pulses from the output; element AND NOT 47 (U2,) toggles trigger 49 (Uji). As a result, the AND-NOT 52 element, to which the pulses from the AND-47 element arrive through the NOT 50 element (DCO), is received. Thus, the subsequent counting pulse, i.e. ambiguity is eliminated. The sequence of counting pulses from the output AND-NOT 52 () begins to flow simultaneously through the element NO 53, the element AND-NOT 55 and the element 35 And 57 into the counter 11 (1) 24) and through. element AND 54 into counter 10 () until counter overflow 10 (iz), after which triggers 46 and 49 through element I-HE 44 and element NO 51 return to their original state by closing the elements. AND-NOT 47 and 52. Thus, in the counter 11 passes .- thirty drowning impulse lasting (). From the output of the one-shot 86 pulse U g enters the block 13 registration-display and provides a census of the measurement results of the time interval of zero duration in the display registers. The pulse also arrives at shaper 87, 25 forming a pulse with duration oo (and gjj), which, as a pulse of the start of calibration, zero is fed to block 12 (Fig. 6) at single input of trigger 64 and switches it. With this signal from the direct output of the trigger 40 ger b4 (Ug,) opens an AND-HE element 65. The first of the counting pulses from generator 1 that passes through the AND-HE element 65 () sets the trigger 66 to the state (Ug), and the U57 element opens. As a result, the simultaneous passage of counting pulses (Uj) to the input of counter 68 through element 57 57 and to input of counter 11 begins. The states of all decades of counter 11 are transmitted to the inputs of AND-NOT 62. The process of simultaneous counting counting them. ger b4 (Ug,) opens an AND-HE element 65. The first of the counting pulses from generator 1 that passes through the AND-HE element 65 () sets the trigger 66 to the state (Ug), and the U57 element opens. As a result, the simultaneous passage of counting pulses (Uj) to the input of counter 68 through element 57 57 and to input of counter 11 begins. The states of all decades of counter 11 are transmitted to the inputs of AND-NOT 62. The process of simultaneous counting counting them. the number of counting pulses, which the counters 68 and 11 lack, occurs until the counter 10 is completely filled. - Since the capacity of the counter 10 is the number of pulses corresponding to Dit until the counting of the counter 11 to the state 0 ... 0. When the counter is 11 9 ... 9, at the inputs of the AND-NE 62 element, the levels 1 coincide and the next counting impulse (Ugj), which passes through the AND-NE 62 element, switches the trigger 64 to the (u5) state, which prohibits the passage of counting pulses through the elements fc YOU AND-HEY 65 and 67. In this case, the counter 68 is recorded in the decimal code number corresponding to the additive component of the error. In the measurement mode of the time interval, the time interval of the RC, then after the measurement, the time interval Ktp, the number of counting pulses, which is missing until this counter is completely filled, corresponds to the time interval Ktj. and is the number of pulses N4, p Ktp / trp. As a result, counter 11, the capacity of which is the number of pulses corresponding to the time interval K €, for a total of 20 0 The number of counting pulses is given, which corresponds to the time interval Ktg + Ktp (Uj). The resulting transfer pulses from the output of the counter 11 are fed to the second input of the counter 2 rough measurement, After graduation. addition of time intervals, i.e. at the moment of overflow of the counter 10, the overflow pulse () of this counter enters the control unit 14 (Fig. 7) on line 79. delay, the output of which „„ T, impulse u, l, delayed by -3 o,. . „P C element AND-NOT 80 ( 20 - 35. , thirty drowning impulse lasting (). From the output of the one-shot 86 pulse U g enters the block 13 registration-display and provides a census of the measurement results of the time interval of zero duration in the display registers. The pulse also arrives at shaper 87, 25 forming a pulse with duration oo (and gjj), which, as a pulse of the start of calibration, zero is fed to block 12 (Fig. 6) at single input of trigger 64 and switches it. With this signal from the direct output of the trigger 40 ger b4 (Ug,) opens an AND-HE element 65. The first of the counting pulses from generator 1 that passes through the AND-HE element 65 () sets the trigger 66 to the state (Ug), and the U57 element opens. As a result, the simultaneous passage of counting pulses (Uj) to the input of counter 68 through element 57 (Fig. 5) and to the input of counter 11 begins. The inputs of the AND-NE 62 element are transmitted to the state of all the decades of counter 11. The process of simultaneously counting the number of counting them- . at counters 68 and 11 proizhod - at counters 68 and 11 Dit until the counting of the counter 11 to the state 0 ... 0. At the state of the counter 11 9 ... 9 at the inputs of the AND-NOT 62 element, the levels 1 coincide and the next counting pulse (Ugj), which passes through the AND-NE 62 element, switches the trigger 64 to the (u5) state, which prohibits the passage counting pulses through the elements AND-NOT 65 and 67. In this case, the counter 68 is recorded in the decimal code number corresponding to the additive component of the error. In the measurement mode of the time interval21 This number is stored in the counter 68 and before each queue measurement after the moment all elements are set to their original state in the parallel code is written in the decades of counter I1. After the calibration is completed, the zero switch 76 returns to its initial state, as a result of which the calibration zero pulse is applied to the inputs of the AND-NE elements 71 and 73 (Fig. 7) of the counting pulses to the input of the IS-NE element 65 (Fig. 6) and pulse setup through the element And 69 (Fig. 6) c. counter 68 stops. At the end of the calibration modes of the conversion coefficients of the start and stop channels and the zero calibration, the device is ready to measure time intervals limited to start-5 table-pulses. Measurement mode (Fig. 11). FIG. The voltages at the outputs of the respective blocks are shown. With the push of the start switch button 90 (fig. 7), a positive voltage drop U {appears, after which the shaper generates a pulse and, which flows through the AND 82 element as a pulse of the initial installation of the device U, into all the blocks devices. In this case, the counter 2 is set to the state 9, .., 97, the counters 10 and II are in the state O. An impulse and s delayed by the delay line 85 on the -СС ,, enters the zero calibration unit 12 (fig. 6) on the assembly of block 70 (Uj-) and provides a census from counter 68 to counter 11 of the numeric code received in the zero calibration mode. After that, the device is ready to measure. Starting and table impulses limiting time interval, to the Start and Stop inputs (Fig. 7) and then through the closed fourth-fifth and seventh-eighth contacts of the switch 76 and el1 (Usj cops AND-NOT 71; 91 and 73, 72, respectively, on the second and third inputs to blocks 5, 7 and 6, 8 on trigger 30 and element 40, respectively (Fig. 3 and 4). The arrival of the starting pulse through the element And 40 on a single input of the trigger 41 causes its switching and the formation of the beginning of the temporary interval Coming start them - 307443 22 pulse to trigger 30 (Fig. 3) switches it (), as a result of which the YN-NOT 32 element opens. Since the arrival phase of the start-pulse relative to the sequence of counts: the pulses is unknown, then the output of the AND-HE element 32 can cause ambiguity . Therefore, the first counter-impulse (s) passed through the IS-NOT element 32, received at the counting input of the trigger 34, sets it to one state. At the same time, the zero potential from the inverse trigger output closes the NAND element. 5 32, and the unit potential from the direct output (Gad) opens the AND-NE 36 element. As a result, the output of the AND-HE element 36 () passes the first pulse following the pulse, which could have an amplitude or duration insufficient for triggering subsequent devices. The signal from the direct trigger output 34 (,) also opens the element   AND-NOT 3, allowing passage through it of counting pulses to the first input of counter 2 of rough measurement. The first of the counting pulses that passed through the IS-NOT element 36, the line 28 for 30 holders (Fig. 3) and the AND 39 element (Fig. 4) to the zero input of the trigger 41, switches it to the zero state and ends up with a time interval t (U, g). -g h 35 Formed time interval five (and, o) is extended by the converter-43 of the block 7 to K, the input pulse of the converter 43 of the block 7 of Ktg duration (U2,) opens element 40 AND-NE 58 in block 9 of addition (Fig. 5), allowing the passage of counting pulses - ow through the AND-NE 58 () element AND 57 (U, 24 counter P, The number of pulses W-Ktg / TQ on the interval K tg is fixed by counter I 1 with capacity K; -1 pulses. In the case of counter II, an impulse occurs transfer, which enters the second input of counter 2 coarse 45 50 55th measurements. Similarly, with the arrival of the stop-g-pulse on the trigger 31, processes for allocating a time interval tp occur (except for the fact that switching of the trigger 35 closes the AND-NE element 3 (as a result, the counting pulses do not pass through the AND-HE element 3 on the first counter input 2 41 those. measurement ends (and length of time. A pulse of duration tp (Ujj,), formed by the trigger 41, is extended by the converter 43 of the block 8 to K times (and,). The output pulse U of the converter 43 of the block 8 with the duration Kt goes to the block 9 of the addition (FIG. 5) to the shaper 45, and also allows the passage of the counting pulses through the element 61 () and the element 60 at the element 54 and further into the counter 10 (Ujg ). The number of pulses N, 1 -Kt on interI p O The shaft Kt is fixed by the counter 10 with the capacity of the LC impulses. From the output of the imaging unit 45, a pulse Ujj of duration Cp, tied to the trailing edge of the pulse Kt, arrives at the single input of the trigger 46 and switches it to the unit state (Upon termination of the pulse Ktg from the converter 43 of the block 7 through the element 48, the prohibition is removed element AND-NOT 47 f as a result of which the latter opens. Since the end of the Ktg and Kt pulses is not synchronized with the sequence of counting pulses, ambiguity can occur, which is eliminated due to the fact that the first of the counting pulses from The number of the AND-47 element (Ujg) switches the trigger 49 (out of,). As a result, an AND-NOT element 52 is opened, to which pulses are received from the NE-47 element through the NOT 50 element (Ujo). Thus, only the 52 element passes through. subsequent counting impulse. The sequence of counting pulses from the output of the element AND-NOT 52 () starts simultaneously to flow through the element NOT 53, the element AND-NOT 55 and the element AND 57 into the counter AND (and through the element 54 into the counter 10 (U- ,.) to Mo; / .ABOUT . . overflow element, counter 10 (U) After that, the triggers 46 and 49 by an overflow pulse through the element AND-NO 44 and the element 51 do not return to their original state, closing the elements AND-NOT 47 and 52. Thus, the number of counting pulses that are missing to counter 11 passes through fill the counter .10. Since the capacitance of counter 10, the number of pulses corresponding to a segment, time, after measuring the time tap Kt, the number of counting HFM pulses that is missing until this counter is completely filled corresponds to the time span Kt, i.e. Ktp 5 -Ktp, and is the number of pulses N {; Ktp / TO. As a result, the counter 11, whose capacity is the number of pulses corresponding to a segment, the time K tTg, in total passes the number of counting pulses corresponding to the time span Kt + Ktp (U24). The transposing impulses and, 5 from the output of counter 11, which appear at the same time, are applied to the second input of counter 2 of coarse measurement, in which they are fixed. The sign of the end of measurement is the pulse, overflow (U ,,) from counter 10, which enters control unit 14 (Fig. 7) on delay line 79. Level 1 at one of the inputs of the element AND-NOT 80 (U) allows the passage of the pulse U ,, delayed by line 79 of the delay at the ST, on one-shot 86 (U 3 From the output of the one-shot 86, a pulse U is fed in duration to the block 13 of the register-display to allow the census of the measurement results from counters 2 and 11 to the register of the register and display. The pulse U also enters the driver 87, which forms a pulse of duration of € 1 (115), which starts the one-shot 88 (and,). A single vibrator 88 adjusts the display time of the value of the measurement result of the time interval and prohibits the passage of the pulses of the end of measurement U .. through the AND-NE element 80.
