Measures ground rod and small grid resistance.
Use in multi-grounded systems without disconnecting the ground under test.
Measure resistance and continuity of grounding loops around pads and buildings.
Measure leakage current flowing to ground or circulating in ground loops.
Conduct quick field checks.
Conduct field surveys and retrieve and analyze readings are a later time.
Check Resistance on Single and Multiple Rods or Grids
Clamp-on Ground Resistance Testers are used in multi-grounded systems without disconnecting the ground under test. The Model 3731 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.
