Perform safe, automated testing of an electrical installation with the Chauvin Arnoux CA740N.
The tester features a comprehensive, built-in automatic testing system which will test the power source, indicator operation and cable continuity with a high degree of accuracy. Continuity testing is performed using both audible and visual indicators.
Both AC and DC voltage can be checked using the CA740N. The tester uses a bargraph LED indicator to show the level of voltage present with green LEDs for voltages lower than ELC and red LEDs for hazardous voltages.
This product is suitable for use both indoors and outdoors and is IP65 rated.
