Measurement Capabilities

The ETCR 3200C is a double clamp earth resistance tester built for electrical professionals who need to verify grounding systems on site. It combines 2/3/4-wire, selection and double clamp methods in one instrument. A 70 mm clamp aperture accommodates large down leads. The unit stores up to 2000 data sets and provides audible and visual alarms.

Intended Users

This tester suits engineers and contractors performing soil resistivity, earth voltage and AC current checks up to 600.0 A. It is not for buyers who need DC current measurement or a clamp aperture larger than 70 mm. Technicians requiring built-in data logging software should look at other models.

Deciding Specification

The double clamp method measures earth resistance from 0.00 Ω to 100 Ω without auxiliary electrodes. This range determines whether the instrument can validate a specific grounding installation without driving test stakes.
