The AEMC Model 6416 Ground Resistance Tester measures ground rod and grid resistance and impedance without the use of auxiliary rods. Clamp-on ground resistance testers can be used in multi-grounded systems without disconnecting or de-energizing the ground system under test it. The Model 6416 simply clamps around the grounding electrode or conductor 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.
The 6416 includes a high sensitivity measurement function enabling measurement of leakage current flowing to ground or circulating in ground loops from 0.2mA to 40A and resistances from 0.01 to 1500Ω. It also offers battery life information at power-up and Auto Power OFF power management. The Buzzer and Auto Power OFF features may be disabled at any time.
Applications for the 6416 include:
Ground electrode system resistance
Bonding/continuity checks
Cell tower grounding verification
Ground measurements on Railroad signaling systems
