With the Chauvin Arnoux CA6422 Earth Tester, personnel may test for 2P resistance measures up to 50k and 3P earth measurements up to 2k with automatic measurement stabilisation while remaining in compliance with EC 61557-1 and IEC 61557-4 standards. The CA 6422's design places all measures and functions on the front panel, making it simple to use even with gloves on. The user interface is further improved by the illuminated LCD panel, which makes it easier to view measurement storage. The NOISE sign will flash when noise voltage is detected, while the Led will offer the operator a visual cue if dangerous voltage is present. The durable CA6422 is 600V CAT IV safety rated and complies with EC 61557-1 and IEC 61557-4 standards. The tester is protected from dust and water spray from all sides by its IP65 rating. The CA6422 has a battery life of up to 2,000 3P earth measurements at 100 when using 6 × LR6 or AA batteries.
