Features
The Greenlee CMGRT-100A Clamp-On Ground Resistance Tester is a hand-held testing device intended to evaluate grounding systems. It has two modes: • Standard Mode: Standard Loop Resistance & Leakage Current Measurements • Advanced Mode: Refine Measurements to find Impedance at the Selected Frequency & to compute Contact VoltageFurthermore, it can also give an idea about the integrity of the ground systems, the quality of connections or bonds within the system.The tester can measure Loop Resistance in the range of 0.01 Ω to 1500 Ω as well as leakage current in the range of 0.2 mA to 40A. It comes with a data storage function, that can log up to 300 measurements (Both Ω and/or A). Furthermore, the meter also allows the user to select test frequency between 50, 60, 128, or 2083 Hz. -
