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).
