Exceptional Buy – Now a Trusted Tool Across Multiple City Units
As a Baltimore City Electrical Inspector, I depend on reliable, accurate equipment for code enforcement and safety verification—and the ETCR2100A+ Clamp Ground Resistance Meter has proven to be an exceptional buy. I use this meter daily in the field, and it consistently delivers precise readings without the need to disconnect grounding conductors. The non-intrusive clamp design saves time and reduces risk, especially on active job sites where minimal disruption is key. The build quality is excellent, the interface is intuitive, and the display is easy to read in all conditions. It performs flawlessly across its full 0.01–200Ω range and has become an indispensable part of my inspection toolkit. I was so impressed with its performance that I recommended it for department-wide use—and I’m proud to say that it has been approved and adopted across several city units. It’s now being used regularly by other inspectors and technicians throughout the department. For municipalities, utilities, and professionals in the electrical field, this tool offers exceptional value, reliability, and efficiency. Highly recommended.

Low-cost meter for reliable ground resistance - but clamp size limits access.
Pro: Very pleased with the operation, repeatability and accuracy of the ETCR2100A. Tested on multiple types of grounding conductors, mostly in an industrial setting. Measurements are made at 1600 Hz so reading includes a portion of the inductive reactance of the grounding conductor added to the ground resistance. Successfully measured grounding conductor impedance from about 5' to 250' long in an active industrial environment. Con: Normal operation requires a start-up calibration with clamp closed and without the grounding conductor present. The Err code is given if this process is not followed. Also it is easy to confuse the over-range indication with the Err code. The split transformer clamp used to make the measurement is larger than some other ground resistance meters and is difficult to get into tight spaces, like measuring grounds in wired panels.
