Tester 43101 - measuring some resistors, cleaning the switch, checking zero setting potentiometer.

The Soviet pointer tester 43101 is a combined device for measuring direct and alternating voltage and current, resistance, and capacitance of non‑polar capacitors. Made in the USSR, it is an analog pointer multimeter. In this video I check the correspondence of the resistors in the ohmmeter circuit, clean the switch and P2K (not shown), check the variable resistor that sets the zero of the ohmmeter, and observe the arrow’s behavior when set to the beginning of the scale with the control tester. The repair of the resistance measurement mode involved preventing switch issues, replacing the RP2 variable changer, eliminating the initial deviation, and fixing poor contact of the wires from the RP2 to the mode switch by replacing and carefully soldering them.
