The invention relates to computational and control k measurement techniques and can be used. It is designed to visually monitor the input, non-transient, and output characteristics of the iLnipoKoro instrument k-tass and measure its static parameters.

The purpose of (to improve the accuracy of the device. On. 1 is a functional; 1 is a diagram of the device; in Fig. 1. 2 a temporary diagram of the operation; Fig. 3, drawn by a beam on: / a CRT crane.

The digital indication block 1 1 is contained in 1) the latest binary-decimal counter 32, block 33, binary counter, st, registers 35 and .36, first multiplexer 37, binary decimal encoder 38 in a seven-meter code, the second ) Oh multin.teksor 39, block 40 () vani imn.chsov illumination, signal generator 41, komnaratory 42 and 43.

The device works with, in a riding way.

The generator 1 pulses (FIG. 2a) are added to the counter 2 and block 11. A register signal is applied to the inputs of the register 3 (FIG. 2m), which is what is added to the input of TsAG1 5 incrementing by each clock pulse the code from counter 2, the signal from output 11, LG 5 (fig, 2l) is controlled by block 8 and through switch 14 and amplifier 28 enters the horizontal-deflecting plates (not shown) of the cathode ray tube (CRT) (fig, 2n ), From the output of amplifier 9, a signal proportional to the current through the analyzed object 10 nostunet on a vertical deflecting plate s CRT (not shown) through a switch 21 and an amplifier 29 (Fig. 2p). On the CRT screen, the characteristic of the object 10 (FIG. 3) is formed. If the voltage at the output of the DAC 5 and the block 13 coincides, the comparator 12 removes the enable signal from the control input of the register 3 (FIG. 2m) and the code corresponding to the voltage at the output of the block 13 is stored in register 3, and the resolution signal is fed to the second information input unit 11, in which the number corresponding to the voltage at the output of ACI 5 is stored for display on the CRT screen, the CRT beam stops at the point corresponding to the input voltage.

supplied from the output of the CAI 5 to the input of the object 10, and the voltage corresponding to the input current (output voltage) volt) of the instrument 10 and removed from the output of the amplifier 9 (Fig, 2 p. l-tj). A point-marker is formed on the screen (FIG. 3). In c, the next moment the unit 11 and the comparator 7 start working (Figs. 2, t - t ,,). With the help of a comparator 7, CAG 6 and counter 2, production B (.1digs measurement of the output parameter is similar to that indicated, however, the input voltage of the object 10 is supplied with a constant voltage from the output of the IIA 5 (Fig. 2; .tj -t). register 3, and the inputs of the amplifiers 29 and 28 through the keys I,; i 20 and 22--26 of the sequence, 1 are connected at this time to the second and third highs of the main current 11, which forms the coordinates of the 1111 axis and the displayed digits) , Last but not least;) ge; 1nk vk ucheni keys i | odet with counter code 4 (fi | -, 2s, (), e), yuschayushchim at the input of block 30, the signal of coincidence voltage On the outputs of the amplifier 9 and I.

corresponding to the number received from the output of one (the counter 32 is recorded in registers 35 and 36, while outputting the character generators) 41 form (t code of the main) character of the digit 8. but with which the CRT beam moves (Fig, 3) . From the outputs of multiplexer 37, the binary signals of the displayed digits are sent to the inputs of the remote control 38, the decoder 38 generates the corresponding seven-segment codes. Synchronously with the movement of the CRT beam along the main circuit, the address of multiplexer 39, which generates a blanking signal, causes only the necessary segments of the main circuit to glow, and if there is a blanking signal, unit 30 switches on key 27, power is applied to the input of amplifier 29 and the beam is outputted screen CRT (Fig, 2 p. p, t, -tg).

In this way, two lines of three digits each are formed. After drawing the numbers, the comparator 43 is triggered (Fig. 2g). which switches the character generator 41 to the integration mode and a positive voltage is supplied from the comparator 42 to the input of the character generator, Block 30 connects the keys 17 and 24 to the inputs of amplifiers 28 and 5 29 and forms the X axis. When forming the axes, the complexer 43 fixes the beam to beam (Fig. 2n) , p, ts -ti), giving the signal to the control input of block 30,

The feature mapping process is conducted as follows. The input of TsAG1 5 is supplied with a digital code increasing by one for each clock pulse and at the output of TsAG1 5 ((linear voltage increases (Fig. 2)). The voltage Uu.An from the output of the DAC 5 at the initial time t, is less than at the output of block 13, the comparator 12 generates a signal (Fig. 2m), which makes the register 3 "n) transparent, i.e. the information passes from the inputs to the outputs. The ramp-down voltage from the output of the PAP 5 is applied to the inputs of the object K) and the amplifier 28 (phi1. 2p), the input is amplified; 1 29 the voltage from the output of the amplifier 9 is lost, tional current analyte MBT) EKTA (Fig. 2p). As a result, characteristic 10 is formed, which is displayed on iKpaiie (Fig. 3). When a match is made, as specified by block 13 and P.LP 5, a comparator 12 is triggered and removes the enable signal (Fig. 2 m, b). Register 3 1 stops being “transparent and remembers the code input | about tension.

The outputs of the register 3 are connected to the PAP inputs D), and its output is set; 1 a constant voltage (Fig. 2 l. Ti) is transmitted through block 8 to the input of the object I) and through key 14 of the input driver 28. and through the switch 21, a voltage is applied to the input of the amplifier 29 from the output of the amplifier 9, which is distorted by the current at the input of the object 10, which is also constant. A point-marker arises on the screen of a CRT, which is part of the displayed characteristic (fnl.). This eliminates the possibility of a mismatch between the marker and the characteristic.

By denying. A differential from the output of the comparator 12 (Fig. 2n, t) in block 11 stores the code corresponding to the voltage on the input of block 13, which is used when displaying chi (}) p on a CRT.

Upon receipt of a "Reset" pulse (Fig. 2c), the device switches to the display mode and changes the output value} | Apr of the (current) object 10. Pa PA outputs and a linearly increasing voltage is formed (Fig. 2k), which is used to measure output voltage (current) of the object 10. Measurement is performed as described above (Fig. 2k. n). Block 1 1 generates the signals necessary for ((normalization of numbers and coordinate axes (Fig. 2n, p, tj - t,)) on the CRT screen (Fig. 3).
