The cathode voltmeter "A4-M2" was produced from the beginning of 1956. Designed to measure DC and AC voltages, DC resistance, capacitance and inductance. The scale is graded in effective voltage values. The device measures direct and alternating voltages up to 1000 V. With a remote divider, the measurement limit can be extended to 10 kV DC. Accuracy of measurement of DC and AC voltages from 3 to 6%. The device allows to measure the resistance to direct current from 1 ohm to 100 meg, inductance from 100 mg to 100 g and capacitances from 100 pf to 100 microfarads. Accuracy of measurement of resistances of 10%, inductances and capacities of 15%. Food from a network of 127 or 220 V, with a frequency of 50 Hz or 115 V, 400 Hz.
