AEMC Instruments 6418 Description:
Quickly and easily clamp this ground resistance tester around the grounding electrode or conductor and measure the resistance to the ground. By performing measurements on intact ground systems, verify the quality of the grounding connections and bonds. Additionally, measure the resistance and continuity of grounding loops around pads and buildings.
Features
- Ground integrity measurement
- Large multi-function bright yellow OLED (organic LED display); 1.89 x 1.55" (48 x 39 mm)
- The clamping diameter accommodates both cable and bus bar
- Storage of measurements (? and/or A, with time-stamping)
- Up to 300 measurements stored
- View stored measurements on the OLED display
- Auto power off function
- Auto hold
- Alarm function with an adjustable set point and buzzer for quick field checks for amps and ohms
- Rugged Lexan? head and body construction resists breakage
- Alarm settings and stored memory information saved during shutdown
- The noise icon and buzzer alert user to the presence of dangerous current levels
- Designed to EN 61010-1, 100 V CAT IV, and 150 V CAT III safety standards
- Automatic calibration of the jaw gap at power-up
Applications
- Ground resistance testing
