LV Current Transducer Ratio Tester

The ETCR 9620B is a specialised instrument for electricians who must verify current-transducer transformation ratios, angle difference, phase and polarity on live 380/220 V systems without interrupting supply. It targets professionals maintaining metering devices in industrial and commercial installations.

Build integration needs

The kit includes a host unit, a primary flexible current clamp with an 8 mm coil diameter for tight cable runs, and a secondary current clamp. Batteries are not supplied due to air-freight restrictions, so users must source them locally before the first job. No English manual ships in the box; documentation must be requested from support after purchase.

Suitability and limits

This tester suits technicians who need on-site, power-on verification of transducer accuracy in 380/220 V networks. It is not intended for engineers requiring automated data logging, software analysis or multi-voltage range testing beyond the specified system voltages.

Questions about this item

What voltage systems can the ETCR9620B test without power interruption?

The ETCR9620B tests current transducers in 380/220V power systems online without requiring a power shutdown.

How does the 8mm flexible clamp coil affect heat during extended use?

The 8mm flexible current clamp coil reaches tight cable spaces easily, reducing physical strain during all-day testing sessions.

Which power source must the buyer supply before using the ETCR9620B?

The standard package excludes batteries due to air shipping restrictions; purchase suitable batteries locally before first use.
