Measuring 3-Phase AC Voltage

Measuring 3-Phase AC Voltage

This meter is primarily designed to measure household AC voltages and is not intended for commercial or industrial use. If you want to measure 3-phase, line-to-line voltages, please note the following:

•Because of the dangers inherent in the measurement of three-phase circuits, we strongly recommend against the use of this meter for such applications.

•If you choose to make the measurements, use extreme care. The actual voltage can be greater than the circuit’s rated voltage (line-to-ground).
