The invention relates to the automator 10, the first RS flip-flop 13, installation and computing, and can be inserted into the state of Log.1 to be used to measure the RS-flip-flop 14, elements And 18 and 19

these are the values of mechanical quantities. are closed, the element OR 16 the discovery of the invention — the expansion is obscured. The contents of counter 5 according to the application by ensuring the integral value of measuring the average values of the measurable mechanical quantity, the range of mechanical quantities independent of the counter 6 — the number of lengths of the measurement interval measured by the current mechanical value are represented by the functional quantity. From this moment on, the initial digital measurement scheme. There is a process for processing the result. The meter contains an anc measurement sensor 1c. The first impulse from the general output, ammunition-time-torus 3 filling pulses through

element 18 and 19, the switch 20 second pulse generator 3 Log.G

and the adder 21d is shifted to the second bit of the register. The digital meter operates as little as 25p. 8, allowing recording of parallel

following code: output of the adder 21 in the river e. When measuring the average value of the hyster 9. This code is equal to the sum of the content of the output signal of the sensor 1 from the analogue counter 5 and 6. Next Log.1 pin output, the output voltage -at is at the output of the third bit that is proportional to, for example, the registrar 8, which resets the torque value, the switch- the previous content of the counter 5. The meter 20 connects the trigger input of the quarter-time pulse of the generator 3 Log.1 time converter 2 is shifted to the output of the fourth p z- to the output clock generator 4 im-series register 8, wherein the input pulses. When sensors are used. The resolution of meter 5 enters an analogue analogue frequency 1 and frequency output 7 output-log. G, allowing information to be recorded, for example, to measure the average output from the output of register 9. At this power 9 the switch 20 connects to the first the processing cycle em to the start-up input of the amplitude-time-measurement result. Level of the Log.G, converter 2 output of the fourth-stage 7 output from the output with frequency output of the register 9 through the second elec- tion by the input of an external signal OR 17 to the serial input

 signifying the beginning of the measurement, the shift register 8, prepares the pulse from the output of the first form-polnepy of the next, similar to the pretl 11 pulses, which are wrapped in the register of the next four-cycle loop processing counter 6 and through the measurement result OR 15 item. A register counter 5, the first trigger 13 setting the number of such cycles is made to come in a digital indicator .10. This is where elements 18 and 19 open. The last loop is the one

the element OR 16 is closed, With this in which the new contents of the counter 5

moment counters 5 and b are filled to become less than the contents of the pulses from generator 3 of filling 6, which leads to the appearance of high pulses and generator 4 clocks of the high bit of the adder 21 and

pulses, respectively (information register 9 level Log. G and block counter 6 - in the additional code) .aniyu element OR 16.
