Three-phase measurement scope

The ETCR 4400 is a multifunction phase voltammeter built for electricians working on three-phase systems. It simultaneously measures voltage amplitude, current amplitude, voltage phase, current phase, the phase between voltage and current, frequency, power, active power, and reactive power. The instrument also displays the vector diagram of three-phase voltage and current in real time.

Suits three-phase field analysis.

This tool suits technicians who need to judge three-phase phase sequence, identify sensibility and capacitance circuits, test secondary circuits, and verify watt-hour meter wiring during line equipment overhaul. It covers single-phase, two-phase, and three-phase modes including three-phase 4-wire and 3-wire configurations. Buyers who only require single-channel data logging or DC measurements should look at something else.

Dual-channel ranges to 20 A and 700 V

The meter provides simultaneously two-channel AC current measurement from 0.001 A to 20 A and simultaneously two-channel AC voltage measurement from 2 V to 700 V. Phase measurement among UI, II, and UU spans 0° to 360° with accuracy of ±0.3°. Voltage and current accuracy reaches class 0.3, and the instrument updates data automatically after wiring.

Questions about this item

What AC current and voltage ranges must the circuit stay within for the ETCR 4400 to measure correctly?

The meter measures AC current from 0.001 A to 20 A and AC voltage from 2 V to 700 V simultaneously on two channels.

Can the ETCR 4400 verify phase sequence and wiring on both three-phase 3-wire and 4-wire installations?

Yes, it supports single-phase, two-phase and three-phase modes including three-phase 3-wire and 4-wire, and can judge phase sequence and watt-hour meter wiring.

How do I confirm the ETCR 4400 is displaying accurate phase angles after connecting the leads?

Phase accuracy is ±0.3° across 0°–360°; watch the real-time vector diagram of three-phase voltage and current to verify correct angular relationships.
