Description
The Ground Resistance & Leakage Current Clamp Meter offers precise non-contact ground resistance measurement from 0.025Ω to 1500Ω. Its True RMS leakage current measurement ranges from 0.3 mA to 30 A. The meter includes a 23 mm jaw that easily fits most conductors and eliminates the need for auxiliary electrodes.
It supports programmable high and low alarms, allowing users to quickly detect abnormal readings. With a data logging capacity of 116 records and an adjustable logging interval from 1 to 255 seconds, this meter provides thorough analysis and monitoring. Its auto-power-off function conserves battery life during extended fieldwork. Designed for multiple grounding applications, it is ideal for telecommunication, electrical power plants, factories, cable TV systems, cellular networks, and gas stations.
