Purpose-built clamp meter
The ETCR 2100A+ is a digital clamp-on ground resistance meter designed for loop-system measurements in power substations, telecom sites, oilfields, construction and industrial electrical equipment. Its 32mm jaw closes around grounding conductors without disconnecting down leads or deploying auxiliary electrodes, so technicians can verify grounding integrity safely and quickly on live systems. The instrument stores up to 99 records for later review.
Replaces auxiliary-electrode testers
Traditional fall-of-potential methods require driving stakes and breaking the grounding circuit; this meter eliminates that work when a closed loop exists, making the jump worthwhile for crews who need rapid, repeatable checks on bonded grounding networks. It also detects ground faults that conventional techniques miss by measuring the combined resistance of the grounding body and lead. The tester is not suited for single-point grounding unless an artificial loop is created near the electrode.
Sustained field operation
Instant start-up and low power consumption support extended measurement sessions without warm-up delays or frequent battery changes. An upgraded relay self-test with advanced algorithms runs continuously to verify internal accuracy, while audible and visual alarms flag interference signals and out-of-range readings during long surveys. The six-button panel and ergonomic grip maintain comfortable, error-free operation across repeated clamp cycles.

Questions about this item
What is the jaw opening size of the ETCR 2100A+ clamp meter?
The clamp jaw opens to 32mm, allowing it to fit around grounding conductors and loops of that diameter or smaller for non-contact measurement.
How do I start a measurement with the six-button panel on the ETCR 2100A+?
Power the unit on for instant start-up, clamp the jaws around the grounding loop, then press the measurement key; the tester automatically detects interference and sounds an alarm if a valid loop is not present.
When should I replace the batteries in the ETCR 2100A+?
Replace the batteries when the low-power indicator appears or the audible and visual alarms fail to activate during the self-test, as the meter relies on sufficient current for its voltage and current coils.
