Vintage Soviet Russian Ussr Combined Electrical Analogue Instrument 43102

There is a hairline crack in glass panel. You can see in photo.It does not effect performance. Meter is still under factory seal.Vintage Soviet Russian Ussr Combined Electrical Analogue Instrument 43102 is designed to measure DC voltage, rms AC voltage sine wave, DC resistance, speed of the crankshaft of the engine, including engines with non-contact ignition system, and the angle of the closed state of the breaker contacts four-, six-and eight-cylinder engines with electric 12V and negative polarity of the "masses".Specifications: Electrical appliances combined analog devices 43102:The limits of the scale (initial and final values ​​of the measuring range) limits. Allowed values ​​of the basic errors of the device in normal conditions of use (Table 2), the values ​​of current consumption device correspond to the values ​​specified in Table 1;Table 1: Values ​​of the combined unit of consumed electrical analog device current 43102MeasurandMeasuring range (initial and final value)Maximum permissible inaccuracyConsumption of no more thanDirect current voltage0V-2V, 0V-20V, 0V-40V± 1,5%0.105 mAAC voltage60V-400V± 2,5%0.510 mADC Resistance0 k = 0, 1 k, 0 k, 100 k± 2,5%0.16 mARotational speed of the engine crankshaft0min 1500min -1, -1, -1 0min-9000min -1± 2,5%15mAThe angle of the closed state of the breaker contacts0 º -45 º, 0 º -60 º, 0 º -90 º± 2,5%15mATable 2 Limits.
