The microcomputer ROM 27 contains diagnostic programs, a drug test, the architecture of the studied body parts and the topography of the points where measurements are to be taken. Before the study from the console 28, the operator sets the program and scope of the study.

Micro VM 27 at block 29 reflects the architecture of the body part to be followed and the topography of the body in which nponsBOflt is needed. The doctor by means of circuit 1 meter 2 performs measurement, which is displayed on the device 3. At the same time, the IHO signal from the output of meter 2 goes to block 4.

algorithm, given in the table. Upon completion of the diagnostic examination of the points indicated in accordance with the program laid down, the microcomputer 27, in accordance with the program of the drug test, presents to the doctor the topography of the point to be tested. The doctor places the search electrode in the specified estrus and achieves the stability of the readings on devices 3 and 5. When a search electrode reaches a stable contact with the skin, the microcomputer 27 delivers code messages to the output port connected to block 7, namely the switch input 5 of the mutator 32. which connects to contour 1 of a predetermined, for example, microresonance contour. The body's response, expressed in a change in electrical conductivity at a point, through block 4 0 is entered into the memory of the microcomputer 27 When the desired response of the body to a particular testing object is achieved, the survey by switch 32 can be terminated and the doctor should stop is the topography of the next point.

The operation of the device according to this algorithm allows the globalization of the measurement values from one touch to another and from one point to another, and also by manipulating the search electrode X.X. 1. K.Z. allows you to enter information into the microcomputer 27. The algorithm when conducting a drug test allows you to conduct testing on the stationary, normalized value of the electrical capability at a point, when the doctor reaches the carry. One contact of the search electrode with the surface of the skin. 0 Block 4. implements this algorithm, additionally provides for the gap isolation of circuit 1 from the means fed from alternating current tm, thereby achieving the necessary requirements for electrical safety 5.

K.Z. allows you to enter information into the microcomputer 27. The algorithm when conducting a drug test allows you to perform testing on the stationary, normalized value of electrical conductivity at a point, i.e. when the doctor reaches the necessary contact of the search electrode with the surface of the skin.

Block A works as follows. The signal from the output of the meter goes to block 13, which controls the operation of keys 8, 10 and 14. The switching logic of keys 8. 10 and 14 is such that it does not ensure simultaneous closure of key 8 and key 14 (Fig. 2). When the search electrode touches the skin, the output signal of the meter 2 always goes from 0 to a positive value, i.e. A positive impulse will form at the output of the differentiator 15 (FIG. 3), and when the search electrode is disconnected from the skin surface, a negative impulse will be formed. since the signal value changes from positive to 0. They transmit a signal from the output of the differentiator 15 through the Shaper Detectors 16 and 17. One of which transmits positive pulses, the other one is negative, and at its outputs both form normalized pulses corresponding to logical G. The signals from the outputs of the detector-formers 16 and 17 are fed to the inputs of the O and 1 settings of the flip-flop 18. The signal from the output of which through the circuit And 19 enters the key 8. When the voltages on the cell 9 and cell 11 are equal, the comparison circuit operates and through the second AND circuit 22 is allowed commutation key 14. When KZ of the electrodes, the signal at the output of the meter is maximum, and threshold scheme 20 is activated. The setpoint is selected with the technological spread of the maximum start, the single-oscillator 21 generates a pulse of a given duration, which is necessary to rewrite the signal from cell 9 to block 6. For the recording time the signal in block 6 to the circuit AND 19 through the inverter 23 receives the key lock inhibit signal 8. Memory cells 9 and 11 can be made with a storage capacitor.

Information input into the microcomputer 27 is controlled by the null organ 25 and the ADC 24. And the recording of the value of electrical conductivity in a drug test is controlled by a signal from the galvanic isolation unit 26. the output of which is connected to the outputs of circuits And 19 and 22.
