Three-phase Digital Phase Voltmeter

The ETCR 4320 measures three AC currents up to 600A and three AC voltages up to 600V simultaneously. It captures phase angles from 0.0° to 360.0° and calculates power parameters. Electricians and field engineers use it for transformer wiring checks and line maintenance.

Sustained measurement capability

The instrument stores up to 500 data groups for extended logging sessions. It handles continuous three-phase monitoring of voltage, current, phase sequence and power factor without interruption. The large caliper jaw accommodates conductors for stable long-term readings on live circuits.

Build and connectivity

A red handheld chassis houses the measurement jaws and display for portable operation. The CT jaw opening of F8mm fits standard conductor sizes found in panel work. The unit ships without batteries due to air transport restrictions and includes no English manual in the box.

Questions about this item

How much heat or noise does the 4320 produce during continuous three-phase logging?

The 4320 is a handheld test instrument with no moving parts, so it generates negligible heat and operates silently during extended measurement sessions.

What must I supply before the 4320 can take readings?

You need to provide your own batteries; the standard package excludes them due to air-shipping restrictions.

Will the 4320 work with the older CT clamps I already own?

The unit is designed for its built-in F8 mm CT size; clamps with a different jaw diameter will not fit the meter’s measurement circuit.
