DISCONTINUED ITEM-Replacement Models: AEMC 6417 (2141.02) Clamp-On Ground Resistance Tester w/ Bluetooth and AEMC 6416 (2141.01) Clamp-On Ground Resistance Tester
The Models 3711 and 3731 mea sure ground rod and grid resistance in any environment without the use of auxiliary ground rods. Clamp-on ground resistance testers are used on multi- grounded systems without disconnecting the ground under test. The Models 3711 and 3731 simply clamp around the ground conductor or rod and measures the resistance to ground fast and accurately.
By performing measurements on installed 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.
Both models include a current measurement function. The probe’s high sensitivity enables measurement of leakage current flowing to ground or circulating in ground loops down to 1mA as well as neutral and phase currents to 30Arms. This feature provides additional information, which is vital in distribution ground networks carrying higher levels of noise and harmonics, that affect power quality.
The Model 3731 offers an alarm function and a memory (logging) function. In the alarm mode, the probe will audibly and visually indicate readings beyond set point. The user may also have the alarm initiated above or below the set point. This alarm feature permits quick field checks where “pass” or “fail” readings will suffice.
