Earth Ground Resistance Tester 0.01-1200O

The ETCR 2000E+ measures earth ground resistance from 0.01 to 1200 ohms without disconnecting the grounding wire or driving auxiliary electrodes. It suits electricians and maintenance crews working on power, telecom, oilfield and industrial earthing systems. The clamp jaw opens to 65 by 32 mm with a 32 mm inner diameter. RS232 output lets users log results to a PC.

99 stored readings and 0.01 ohm resolution

The tester stores up to 99 groups of measurements and resolves resistance to 0.01 ohm across the full range. Sound and light alarms flag readings that exceed set limits. Maximum operating current stays below 50 mA for extended battery life. Self-test completes at power-on without a long wait, so the instrument is ready for immediate use.

Handheld clamp design with six-button panel

The compact clamp form factor fits tight enclosures and overhead conductors where traditional three-pole testers cannot reach. Six front-panel buttons control ranging, memory, alarm thresholds and data transfer. RS232 connectivity offloads stored data for reports or trend analysis. The tool replaces auxiliary rods and long test leads, freeing the operator to move quickly between test points.

Questions about this item

Will the 65 by 32 mm jaw fit around the same grounding conductors I use with my older clamp meter?

The jaw opening is 65 by 32 mm with a 32 mm inner diameter, so it will accommodate conductors that fit within those dimensions.

How can I verify the 0.01 ohm resolution is working correctly after I start using the tester?

The tester performs an immediate self-test on power-up and uses sound and light alarms to confirm proper operation during each measurement.

Does the package include the RS232 cable for downloading the 99 stored readings, or must I buy it separately?

The supplied data lists only the tester itself in a single pack; any RS232 cable or software for data transfer would be a separate purchase.
