Amperevoltommeter `` Ts56 ''.

Instruments for adjusting and controlling the PTA.Amperevoltommeter "Ts-56" and "Ts-56/1" were produced from the beginning of 1963. Amperevoltommeter Ts56 / 1 is designed to measure AC and DC current and voltage with high accuracy. There is one limit for measuring resistances. The device is distinguished by high sensitivity and a wide range of measured values, currents up to 6 amperes and voltages up to 900 volts. A separate terminal of the instrument is designed to measure voltages up to 75 millivolts and currents up to 0.3 milliamperes. Three switches are used to select operating modes. Measurement error on alternating current 1.5, in other modes about 1%. Power supply for one element 332. The Ts-56/1 ampere-voltmeter differs from the Ts-56 ampere-voltmeter only by a higher class of measurement accuracy.
