Intended for measuring the RMS phase-to-neutral and phase-to-phase voltages in a three-phase network with a solidly earthed neutral, with a built-in input selector between phases.
Key features
Built-in input selector between phases for star and delta connection.
Replaces three moving-coil voltmeters.
Voltage shown on a three-digit display.
Powered from one phase, (100–265) V.
Panel mounting with rear terminals.
The RMS voltage is found by sampling the voltage many times per cycle and processing the results mathematically in real time
