DESCRIPTION
The 931B True RMS Differential Voltmeter is designed for rapid measurements of ac waveforms regardless of their shape. Accuracies to ±0.05% of reading are obtained in a simple-to-operate portable instrument with a five digit readout and automatic indicating decimal point. The instrument employs the principle of the differential thermocouple transfer standard to obtain its high degree of accuracy. It incorporates unique solid-state circuitry to accomplish the transfer automatically and almost instantly as the voltage readout dials are adjusted to their proper setting. •Voltage range: 0.003 to 1100 V in 11 ranges. •Frequency range: 2 Hz to 2 MHz.
