Ground Resistance Tester Clamp The AEMC 3731 Clamp-on Ground Resistance Testers are used in multi-grounded systems without disconnecting the ground under test.

By performing measurements on intact ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured.
