A DC digital voltmeter in which a simple standard cell is used for the reference voltage to measure down to 0.2 mV, with an overall accuracy of ±0.2% of maximum readout on each range. With four ranges with maximum readouts of 1, 10, 100 and 1,000V DC. on mechanical counters with automatic decimal point indication. Input impedance is 2.2MΩ. The average readout time is two seconds but for maximum readout it is five seconds.
See also the similar 652AX Digital Voltmeter model with a Zener diode reference to measure down to 0.1mV and an accuracy of ±0.1%.
