Earth resistance tester for loop systems

The ETCR2000+ clamp meter measures grounding resistance from .01 to 1200 ohm without disconnecting the earth wire or driving auxiliary electrodes. It stores up to 99 groups of readings for later review. A 65 by 32 millimetre jaw opens to a 32 millimetre diameter, fitting typical conductors in power, telecom, meteorology, oilfield and industrial installations. Six front-panel buttons give direct access to measurement and memory functions.

Sustained-use behaviour

Maximum operating current stays at or below 50 mA, so battery drain remains low during extended survey sessions. The instrument powers up and enters test mode immediately, eliminating the long self-test delays found in older designs. An integrated sound and light alarm signals when readings exceed a preset threshold, allowing continuous monitoring without watching the display. Digital integration algorithms handle the measurement cycle automatically, keeping performance stable over repeated tests.

Pre-purchase checks

Verify that the conductor diameter does not exceed 32 millimetres so the clamp can close fully. Confirm the expected resistance range falls within .01 to 1200 ohm, as the tester cannot read outside those limits. Ensure the application involves a closed-loop grounding path, because the clamp method requires return current through the earth system. No auxiliary rods or test leads are needed, but the grounding circuit must be complete for a valid measurement.

Questions about this item

How much current does the ETCR2000+ draw when running continuously all day?

The maximum operating current does not exceed 50 mA, keeping power consumption low during extended use.

What jaw size must the earth conductor fit through for the ETCR2000+ to clamp correctly?

The jaw opening measures 65 by 32 mm with a 32 mm diameter, so the conductor must fit within those dimensions.

Can the ETCR2000+ measure a grounding system without disconnecting the earth wire or driving auxiliary electrodes?

Yes, it measures loop resistance directly on live grounding systems without breaking the wire or using auxiliary electrodes.
