AEMC's Models 6416 and 6417 measure ground rod, grid resistance and impedance

AEMC's Models 6416 and 6417 measure ground rod, grid resistance and impedance without the use of auxiliary rods. They can be used on multi-grounded systems without disconnecting or de-energizing the system. The Models 6416 and 6417 clamp around the grounding electrode or conductor (connected to a low-resistance ground system) and measure the resistance to ground. By performing measurements on intact ground systems, the user also verifies the quality of the grounding connections and bonds.

Ground voltage is displayed and an alarm sounds when unsafe conditions may exist. User-selectable test frequency improves measurement accuracy in inductive environments and loop resistance indication alerts the user when the measurement may be through a loop and not the earth. Resistance and continuity of grounding loops around pads and buildings may also be measured.

The Model 6417 is available with an Android application for easy data display programming, downloading, printing and emailing test results from your mobile device in real-time or from stored data. An OLED display provides easy reading in bright sunlight or in total darkness. Measurements are from 0.1 to 1500 Ohms and current up to 40 AAC.

Both models include a current measurement function. The probe’s sensitivity enables measurement of leakage current flowing to ground or circulating in ground loops from 0.2mA to 40A and resistances from 0.01 to 1500Ω.

Both models offer battery life information at power-up and Auto Power OFF for power management. Additional features are also displayed on the large OLED display to ensure precise measurements. The Buzzer and Auto Power OFF features may be disabled at any time.
The Model 6417 offers an alarm function and a data storage function. In the Alarm mode, the probe will audibly and visually indicate if the reading is beyond an input set point. The user may also have the alarm activate above or below the set point. This alarm feature permits quick field checks where only “pass” or “fail” readings are required.

The data storage function saves up to 300 tests (Model 6416) and 2000 tests (Model 6417) measurements, time stamping, volts, amps & resistance. This enables the user to conduct field surveys, and to retrieve and analyze the readings at a later time. The alarm settings and stored data are saved when the ground tester is turned off.

Two new features unique to AEMC are test frequency selection and touch voltage indication. The ability to select the test frequency provides more accurate measurements in inductive environments. Displaying voltage computed from current and resistance measurements provides an extra level of safety for the user, indicating a potentially dangerous touch condition.
