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. The Model 6417 simply clamps around the grounding electrode or conductor and measures the resistance to the 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 detects a potentially dangerous touch condition
• Loop resistance indication alerts the user to the fact that the measurement may not be ground resistance

The Ground Resistance Tester Models 6416 and 6417, measure ground rod and grid resistance without the use of auxiliary rods. Clamp-on ground resistance testers can be used in multi-grounded systems without disconnecting the ground system under test or de-energizing them. Models 6416 and 6417 simply clamp around the ground conductor or rod and measure the resistance to the 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.

Two new features unique to AEMC are tested frequency selection and touch voltage indication. The ability to select the test frequency provides more accurate results in inductive environments. Displaying voltage derived from current and resistance measurements provides an extra level of safety for the user, indicating a potentially dangerous touch condition. Both models include a current measurement function. The probe’s high sensitivity enables measurement of leakage current flowing to the 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-Off for power management. Additional features are also displayed on the large OLED display to ensure precise measurements. The Buzzer and Auto-Off Power features may be disabled from the push-buttons at any time.

Both offer an alarm function and a data storage function. In the Alarm Mode, the probe will audibly and visually indicate if the reading is beyond the user-programmed set point. The user may have the alarm activated 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 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. The 6417 provides Bluetooth transmission to a PC for analysis and report generation via the included DataView software.
