ETCR 2100C+ Multi-Function Clamp Earth Resistance Tester 0.010-1200Ω 20.0A 32mm 99 Records

Multi-Function Clamp Earth Resistance Tester

The ETCR 2100C+ is a handheld clamp meter designed for electricians and maintenance technicians who need to measure earth and loop resistance without disconnecting the grounding system. It covers a resistance range from 0.010 Ω to 1200 Ω and measures leakage current from 0.00 mA up to 20.0 A. The 32 mm jaw opening accommodates standard grounding conductors and small busbars.

Sustained Operation and Data Handling

The tester uses advanced digital integration algorithms to eliminate the long self-test delay found in older models, allowing immediate start-up for continuous field work. An audible and visible alarm triggers when resistance exceeds a user-set threshold between 1 Ω and 199 Ω, while an interference signal indicator helps identify noisy environments during extended sessions. Internal memory stores up to 99 measurement records for later review.

Pre-Purchase Compatibility Check

Verify that the conductor or ground rod you intend to test fits within the 32 mm clamp aperture, as larger cables or busbars will not close the jaws fully. Confirm that the expected earth resistance values fall within the 0.010 Ω to 1200 Ω range and that leakage currents do not exceed 20.0 A. The device operates as a standalone instrument and requires no external leads or auxiliary electrodes for clamp-based measurements.
