ETCR 3200 Double Clamp Tester
The ETCR 3200 is a multi-function grounding resistance tester built for electricians and field engineers who need to verify earthing systems on site. It supports five measurement methods including the double-clamp technique for looped or mesh grounds where auxiliary stakes cannot be driven. The large 68 mm clamp jaw accommodates thick down-leads and busbars. Data logging stores up to 2000 reading sets for later review.
Measurement Ranges and Methods
Earth resistance is covered from 0.01 Ω to 30.00 kΩ across 2-wire, 3-wire, 4-wire, selection and double-clamp modes. Soil resistivity spans 0.01 Ω·m to 9000 kΩ·m. Earth voltage reads AC 0.1 V to 100.0 V, while AC current measurement reaches 0.01 mA to 600 A. An audible and visual alarm flags readings that exceed user-set thresholds.
Pre-Purchase Checks
Confirm the clamp jaw opening suits the largest conductor you must encircle. Verify that the expected earth resistance values fall within the 0.01 Ω to 30.00 kΩ span and that soil resistivity tests will not exceed 9000 kΩ·m. Ensure the AC current range up to 600 A covers the leakage currents you plan to measure. The tester requires no auxiliary stakes for the double-clamp method, but the 2/3/4-wire methods do need test electrodes.

Questions about this item
Should I choose the double-clamp method or the 4-wire method for my grounding tests?
Use the double-clamp method for quick checks up to 100 Ω without auxiliary electrodes; switch to the 4-wire method when you need the full 0.01 Ω to 30.00 kΩ range and higher accuracy on complex or mesh grounding systems.
What does the 30.00 kΩ upper range mean when I am on site?
It lets you measure high-resistance electrodes and soil resistivity up to 9000 kΩ·m in a single instrument, so you can verify both low-resistance substation grids and high-resistance lightning-protection earths without changing testers.
How does the 68 mm clamp jaw size limit what I can measure?
The 68 mm jaw accommodates large grounding down-leads and busbars, enabling double-clamp and AC current measurements up to 600 A on thick conductors that smaller clamps cannot encircle.
