Double-clamp phase meter

The ETCR 4200 is a digital phase voltmeter that clamps around two conductors at once. It measures AC current up to 600A and AC voltage up to 600V without breaking the circuit. The instrument also reads phase angle from 0.0° to 360.0°, frequency, power values and power factor. A 35mm by 40mm jaw opening fits large cables in field-testing work.

Electricians doing live three-phase checks

This tool suits electricians and maintenance teams who need simultaneous dual-channel readings on energised three-phase systems. It identifies transformer wiring groups and distinguishes inductive from capacitive loads. Technicians who only require single-channel voltage or current checks, or who work exclusively on low-voltage DC circuits, will not use the double-clamp function.

600V maximum line voltage

The tester is rated for line voltages below 600V, so it cannot be used on higher-voltage distribution networks. This limit decides whether the meter matches the installation being tested. The 35mm by 40mm CT size also determines the maximum conductor diameter that can be clamped.

Questions about this item

What voltage and current ranges must the circuit I test stay within for the ETCR 4200 to measure correctly?

The meter measures AC voltage up to 600 V and AC current up to 600 A on both channels simultaneously.

Can I use the 35 mm by 40 mm clamps on the older busbars in my panel without removing insulation?

Yes, the CT jaws open to 35 mm × 40 mm, allowing non‑contact measurement on insulated conductors that fit inside that aperture.

How do I confirm the phase reading on the display is accurate after I connect both clamps?

The screen shows phase angle from 0.0° to 360.0°; a stable reading within that range and matching the expected wiring group confirms correct operation.
