The Chauvin Arnoux CA 6424 earth tester can be used for 2P and 3P earth measurements in total safety. Text markings and colour coding help users to avoid connection errors. It can also measure the voltage up to 600 V. All the measurements and functions are directly accessible on the front panel, even when wearing gloves. Special connection technology for the G72 clamp allows measurement of the line (phase) current and leakage current, from 0.5 mA to 60 A. There is a dedicated key for cable compensation. A LED indicates when a hazardous voltage is present, while the NOISE symbol flashes to indicate when a noise voltage is present.
