Use this ground resistance tester to measure grounding electrodes and grid resistance without auxiliary rods. In addition, the clamp-on feature can be used in multi-grounded systems without disconnecting the ground system under test by simply clamping around the ground conductor or rod and measuring the resistance to the ground.
Use this ground resistance tester to measure grounding electrodes and grid resistance without auxiliary rods. In addition, the clamp-on feature can be used in multi-grounded systems without disconnecting the ground system under test by simply clamping around the ground conductor or rod and measuring the resistance to the ground.
Ideal for system troubleshooting in commercial, industrial, and utility applications, this ground resistance tester allows for stakeless ground loop testing and non-intrusive leakage current measurement. In addition, it has Bluetooth communication and an alarm function with an adjustable set point and buzzer for field checks.
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 can also be measured.
Features
Current measurement function
The ground tester’s high sensitivity enables measurement of leakage current flowing to ground or circulating in ground loops from 0.2 mA to 40 A and resistances from 0.01 to 1500 W.
Battery life
Battery life information is displayed at power-up and the Auto Power OFF feature can be enabled for power management. Additional features include the large OLED (Organic Light Emitting Diode) display that ensures high readability of data. The Buzzer and Auto Power OFF features can be disabled at any time.
Alarm function
This model is equipped with an alarm function and a data storage function. In the Alarm mode, the probe will audibly and visually indicate when the reading is beyond an input set point. You can also 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.
Data storage function
Logs up to 2000 measurements (W and/or A). This enables you to conduct field surveys, and to retrieve and analyze the readings at a later time. The alarm settings and stored data are saved on the ground tester and remain stored even when the instrument is turned OFF. You can retrieve and analyze the results at a later time with DataView® software or with an Android app through the Bluetooth communication port.
