Earth Resistance Tester for Field Measurement

The ETCR 3000+ is a digital instrument built for electricians and maintenance crews who need to verify ground resistance on site. It supports both three-wire and two-wire measurement methods to suit different installation conditions. A unique wire-resistance calibration function removes lead-error from low-value readings. The tester is designed for long-term precision and stability in varying environments.

Resistance Range .10 to 2000 Ω

The meter covers a span from .10 Ω up to 2000 Ω, giving headroom for most commercial and industrial earthing systems. Low-end resolution allows accurate checks on tight specifications, while the upper end handles higher-resistance electrodes. Readings outside this window fall beyond the calibrated range. The range itself is the primary gauge of whether a given site can be tested with this unit.

Batteries and Manual Not Included

The standard package ships without batteries because air-freight regulations prohibit their inclusion; users must source cells locally before first use. An English user manual is also absent from the box and must be requested from customer service after purchase. Buyers who need an out-of-the-box solution with documentation and power included should plan for these extra steps.

Questions about this item

Will the ETCR 3000+ tester work with my existing 2-wire test leads?

Yes, the ETCR 3000+ supports both 2-wire and 3-wire measurement methods, so your current 2-wire leads can be used for basic ground resistance checks.

How can I verify the ETCR 3000+ is reading correctly after I set it up?

Use the built-in wire resistance calibration function to null out lead resistance, then measure a known ground rod; the display should show a stable value within the .10 to 2000 Ω range.

What comes in the box with the ETCR 3000+ and what must I buy separately?

The box contains the ETCR 3000+ tester only; batteries are not included due to shipping restrictions and must be purchased locally, and the English manual is not printed in the package.
