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).
