AEMC 3731 2117.61 Clamp-on Ground Resistance Tester
Keterangan
The Clamp-on Ground Resistance Tester Model 3711 measures ground rod and small grid resistance through any season, without the use of auxiliary ground rods.
Clamp-on Ground Resistance Testers are used in multi-grounded systems without disconnecting the ground under test. The Model 3711 simply clamps around the ground conductor or rod and measures the resistance to ground. 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.
Features:
Simple and fast clamp-on operation - no leads, no auxiliary rods or spacing requirements. No need to disconnect neutral service
Direct reading of ground resistance from 0.01© to 1200©
Direct reading of continuity and ground loop resistance
Direct reading of ground leakage or phase current from 1mA to 30Arms
