What this tester measures

The ETCR 2000C is a clamp-style earth resistance tester designed for electricians and maintenance engineers who need to verify grounding systems without disconnecting the down lead or driving auxiliary electrodes. It covers a measurement range from .010 to 1000 Ω and operates safely on live looping systems in power, telecom, meteorology, oilfield and industrial installations.

Who this suits and who it does not

The instrument suits technicians who require fast, non-intrusive checks on existing grounding loops and who can source their own batteries locally, as none are supplied in the box. It does not suit users who need an English-language manual in the package or who must measure isolated electrodes where no return path exists for the clamp method.

Deciding specification — measurement range

The single figure that decides fit is the .010 to 1000 Ω resistance range; if the expected ground resistance falls outside this window, a different tester will be required.

Questions about this item

How do I install the ETCR 2000C for a ground-loop measurement, and what step is often missed?

Clamp the jaws around the grounding down lead without breaking the circuit; the step often missed is verifying the jaws are fully closed and clean so the induced current loop is complete.

What maintenance or replacement will the ETCR 2000C need later?

The unit ships without batteries due to air-shipping rules, so you must supply and periodically replace the required cells; no English manual is included, so keep the manufacturer's contact for documentation.

What limit appears first during sustained use of the ETCR 2000C?

The measurement range tops out at 1000 Ω, so any grounding resistance above that value cannot be read and will show as over-range during extended testing.
