AEMC 6417 Clamp-On Ground Resistance Tester

                                                                      

The Ground Resistance Tester Model 6417 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 6417 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.

Three new features unique to AEMC^® are:

• Test frequency selection provides more accurate results in inductive environments
• Touch voltage indication  indicates the voltage on the display along with a warning buzzer when the voltage derived from current and resistance measurements detect a potentially dangerous touch condition
• Loop resistance indication alerts the user to the fact that the measurement may not be ground resistance

The Model 6417 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. There are alarm and data storage functions, which are saved when the tester is turned off.

The DataView^® software included provides the ability to configure and retrieve data from the Model 6417 through Bluetooth^® communication, as well as the ability to generate reports.

• Touch voltage is displayed to alert user to potential unsafe conditions
• Large multi-function, bright yellow organic display (OLED) is visible in all lighting conditions
