ETCR

ETCR2000C+ Digital Clamp Earth Resistance Tester 0.01-1200 65mm×32mm

SKU CH-YE39-GEQH3

Measures grounding resistance 0.010–1200 Ω and leakage current 0.00–20.0 A without disconnecting leads, stores 99 records, and clamps conductors up to 65×32 mm

  • Loop resistance measured without disconnecting leads or auxiliary electrodes
  • Wide 0.010 Ω to 1200 Ω range with 0.001 Ω resolution
  • Clamp jaw 65 mm × 32 mm fits various conductor sizes
  • Current measurement 0.00 mA to 20.0 A with 0.05 mA resolution
  • Stores 99 records; audible and visual alarms for interference detection

Wide-Application Clamp Earth Tester

The ETCR2000C+ is a digital clamp meter for measuring grounding resistance in power, meteorology, oilfields, construction and industrial electrical equipment. It operates on loop systems without disconnecting down leads or using auxiliary electrodes. The tester detects ground faults that traditional methods miss and measures the combined resistance of the grounding body and lead. Instant start-up and a lightweight ergonomic design support fast, comfortable field use.

Loop-Resistance Measurement Range

Resistance is measured from 0.010 to 1200 with 0.001 resolution and current from 0.00 mA to 20.0 with 0.05 mA resolution using the R=E/I principle. The clamp jaw opens to 65mm×32mm to fit a variety of conductors. Upgraded relay self-test algorithms and interference-signal detection with audible and visual alarms ensure reliable readings. Up to 99 records can be stored in internal memory for later review.

For Loop-System Ground Testing

This instrument suits technicians who need safe, rapid loop-resistance checks on live grounding systems without breaking the circuit. It is not for buyers who must measure single-point grounding resistance directly, as the method requires a closed loop or an artificial loop near the electrode. Users needing wireless data transfer or PC software integration should look at other models, as those features are not included.

Questions about this item

What does the 0.01 to 1200 resistance range cover on a live grounding system?

It measures the combined loop resistance of the grounding body and its lead without disconnecting the down conductor, from 0.010 up to 1200.

How does the clamp interface limit the size of conductors I can test?

The jaw opening is 65mm by 32mm, so only cables or earth leads that fit inside those dimensions can be clamped for loop measurement.

What physical space do I need to close the jaws around a grounding lead?

The clamp requires a clear 65mm by 32mm aperture to encircle the conductor, so the lead must be accessible and free of insulation buildup at that point.
