  • Resolution of .001 across .01 to 200 range
  • 65 mm by 32 mm clamp fits varied conductors
  • Stores up to 99 readings for later review

Clamp Ground Resistance Tester 0.01-200 Ω

The ETCR 2000A+ is a clamp-on digital meter for measuring grounding resistance in power substations, telecommunications, oilfields, construction and industrial electrical equipment. It operates on loop systems without disconnecting the down lead or driving auxiliary electrodes. The instrument detects ground faults that traditional methods cannot identify and measures the combined resistance of the grounding body and lead.

Replaces auxiliary-electrode test kits

This tester removes the need for separate current stakes, voltage probes and long test leads when a closed loop path exists. The jump is worth it whenever breaking the grounding connection is unsafe, impractical or time-consuming. It stores up to 99 readings and provides audible and visual alarms for interference or out-of-range results, with a clamp jaw opening of 65mm×32mm.

Suits loop-only grounding checks

The unit is built for technicians who must verify loop resistance quickly and safely in live environments. It is not for buyers who need to measure single-point grounding electrodes without an artificial loop, nor for users who require a four-wire soil resistivity survey. The measurement range spans 0.01 to 200 with 0.001 resolution.

Questions about this item

What conductor size fits the 65mm×32mm clamp opening?

The clamp jaws accept conductors up to 65 mm by 32 mm, so any grounding lead or busbar that fits within that rectangular aperture can be measured without disconnection.

Which step do users most often miss when setting up a loop resistance test?

The tester measures loop resistance only; you must create an artificial loop near the grounding electrode before clamping, otherwise the reading will be invalid.

How many stored readings can the meter hold before old data is overwritten?

Internal memory stores 99 records; once full, new measurements overwrite the oldest entries unless downloaded first.
