Millivolt-milliammeter `` M-82 ''.

Instruments for adjusting and controlling the PTA.The millivolt-milliammeter "M-82" has been produced by the Leningrad plant "Vibrator" since 1965. M82 is a portable laboratory multi-range device of a magnetoelectric system with direct reading. Designed to measure current and voltage in DC circuits. Main technical characteristics: Millivolt-milliammeters were manufactured with 12 measurement ranges: 6 for current and 6 for voltage: 0 - 0.15 - 0.6 - 1.5 - 6.0 - 15 - 60 mA and 0 - 15 - 30 - 150 - 600 –1500 - 3000 mv. The accuracy class of the device is 0.5. The change in the readings of the device when the temperature changes away from the normal (+ 200C) no more than + 1%, from the upper limit of the scale for every 100 units. The change in the readings of the device from the influence of an external magnetic field is no more than 0.5%. Current consumption at 0.15 mA millivolt limits. Insulation test voltage 2 kv. Overall dimensions 310x200x120 mm. The weight of the device is 4.5 kg, with a case of 6.0 kg. Design: The devices are made in a plastic dustproof case. The scale of the device is two-row, with a mirror reading and is divided into 100 and 150 divisions, 140 mm long.
