Digital Clamp Earth Resistance Tester
The ETCR ETCR2000A+ is a clamp-on digital tester designed for measuring ground resistance and loop resistance without disconnecting ground wires or using auxiliary electrodes. It serves electricians and technicians working in power, telecommunications, meteorology, oil fields, architecture and industrial electrical equipment. The instrument stores up to 99 data sets for later review. An integrated alarm function alerts the user when readings exceed a set threshold.
Measurement Range and Jaw Limits
Resistance is measured from 0.01 ohm up to 200 ohm with a display range of 1 to 199 ohm. The clamp jaw opening measures 65 by 32 millimetres, which sets the maximum conductor size that can be encircled for a valid reading. Measurements rely on a closed loop path; isolated electrodes without a return circuit cannot be tested with this method. Accuracy and resolution are fixed by the instrument design and cannot be adjusted by the operator.
Pre-Purchase Setup Checks
Confirm that the conductors you intend to test fit within the 65 by 32 millimetre jaw opening. Verify that the grounding system under test forms a complete loop so the clamp can induce and sense current without auxiliary stakes. Ensure the expected resistance values fall within the 0.01 to 200 ohm range. Check that the 99-record memory capacity meets your data-logging needs for a typical job.

Questions about this item
What does the 0.01-200 ohm range mean for everyday ground-loop testing?
The tester reads from 0.01 ohm up to 200 ohm, so it covers both very low-resistance bonds and higher-resistance earth electrodes without changing instruments.
How does the clamp-on design affect a measurement on a live grounding system?
The 65x32 mm jaw clamps around the conductor, letting you measure loop resistance without disconnecting the ground wire or driving auxiliary electrodes.
What does the 99-set memory limit mean for field surveys?
You can store up to 99 readings internally before you need to offload or overwrite data, which suits typical single-day inspection routes.
