For safe and simple 2P and 3P earth measurements, the Chauvin Arnoux CA6424 Earth Tester is the best tool. The users are assisted in avoiding connection issues by both text annotations and colour coding. With all measurements and functionality easily accessible on the front panel, which can be used even with gloves on, users are able to monitor voltage up to 600V. The CA6424 allows the user to immediately check the integrity of the H stake thanks to automatic start up in 2P earth measurement mode. The CA6424 calculates the differences in percentage proportion to the average while utilising the 3P earth mode and memorises the 52%, 62%, and 72% measurement values. If the difference is too great, a flashing display with the percentage value is shown on the screen. Thanks to the unique connection technology for the G72 clamp (optional), users can use the CA6424 to measure line (phase) current and leakage current from 0.5mA to 60A. The CA6424 contains a key specifically for cable compensation, and when a hazardous voltage is found, the LED screen flashes the NOISE sign to warn that there is noise voltage present. Measurement accuracy will be improved by the CA6424's automatic change from a frequency of 128Hz to 256Hz if a noisy environment is detected. With the CA6424's three displays and backlit screen, users may monitor useful measures, any errors in measurements or recorded values, as well as supplemental data like USE and HR, all on a single screen. The CA6424 is 600V CAT IV rated and complies with IEC 61557-1 and IEC 61557-4. The device has been drop tested to 1 metre as per IEC 61010-1 and is IP65 rated, providing protection from dust and low pressure water jets from any direction.The CA6424 is a 6 rechargeable battery-powered instrument with a battery life of up to 1500 measures at 3P earth measurements at 10 and a deactivatable automatic power-off feature.
