True RMS Volt Amp Meter
True RMS Volt Amp Meter that accurately measures complex, non-sine wave signals. 0.02 to 200 V and 0.02 to 100 Amps ranges. External Current Shunts provide minimal circuit disruption.
The VM-10A-1 is a true RMS Voltmeter implemented with Linear Technology’s patented LTC1966 converters in terms of stability, accuracy, frequency response, input level linearity, complexity and crest factor dynamics.
A 20 dB amplifier provides 0.02 to 200 VAC RMS range for the converter driving a three and half digit digital panel meter. A “Specific Use” current shunt measures peak and true RMS current. Five current shunts cover 0.02 to 100 Amp RMS and are ideal for measuring rectifier, transformer and capacitor currents in low voltage DC power supplies. Caution must be used as the current shunt does not provide galvanic isolation - the low side shunt is connected to the measured circuit.
