Differential voltmeter V1-12 for checking voltmeters (V112, V1 12, b1-12, b1 12, b112)

Designed for the issuance of calibrated discrete values ​​of DC voltage and current.
The drift of the output voltage (in percent) for 8 hours is not more than ± (0,001 + 0,0001 Uc / U) for 2000 hours - less than ± (0,004 + 0,0004 Uc / U).
The maximum load current at voltages up to 100V - 110mA at a voltage above 100 V - 11 mA.

Differential voltmeter V1-12 for checking voltmeters  is designed for the issuance of calibrated discrete values ​​of DC voltage and current and is used as a multi-valued model measures for the verification of measuring instruments DC.
Differential voltmeter V1-12 for checking voltmeters  can also be used as a measuring amplifier with the DC-gain of 1, 10 and 100, as well as the differential voltmeter for measuring DC voltage.
Differential voltmeter V1-12 for checking voltmeters  has an analog output that provides the ability to measure and record volatility (increments) DC voltage.
