CLAMP-ON GROUND RESISTANCE TESTER

The clamp-on ground resistance tester enable the users to measure ground resistance of ground rod without the use of auxiliary ground rods. Clamp-on ground resistance tester are used in multi-grounded systems without disconnecting the ground under test.

Ground resistance (autorange) up to 1500 Ohm.

Continuity: beep if less than 40 Ohm

Ground / leakage current: up to 15 A

Conductor size: 23 mm
