Soviet pointer tester 43101 is a combined device for measuring direct voltage and current, alternating voltage and current, resistance and capacitance of non-polarity capacitors. Made in USSR! Analog pointer multimeter.
In this video, I check the correspondence of the resistors participating in the operation of the ohmmeter circuit, clean the switch and P2K (not shown in the video about P2K), check the variable resistor for setting the zero of the ohmmeter, check the behavior of the arrow when set to the beginning of the scale with the control tester.
Actually, the repair of the resistance measurement mode was reduced to the prevention of switches, the replacement of the RP2 variable changer and the elimination of the initial deviation. There was also a poor contact of the wires going from the RP2 to the mode switch - not shown in the video, just replaced the wires and carefully soldered.
