The device works as follows.

When the cathode bar of the working positions of the bath is found through the resistor 8 iqioTek- 1 (g. The voltage drop across the resistors 8 is fed to the amplifiers 1, and then to the first inputs of the comparators 2. The signal at the other inputs of the comparators 2, generated by the power source (. is almost equal to the voltage on the test coil oh oh, since the drop in the voltage on the diodes 4 is idle due to the leakage of the microcircuit from the source 6 (the current comes from the source 6 on pe.uicToj) 5, diode 4, test contact 9).
