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:
