Chauvin Arnoux Voltage and Continuity Tester C.A 745N The C.A 745N voltage and continuity tester can test AC and DC voltage up to 690 V, with automatic AC or DC detection. It displays the resistance value on 3 thresholds and also offers audible continuity testing. The C.A 745N can be used for single-pole phase testing, there is no risk of tripping high-sensitivity RCDs when performing a phase/earth test. The tester is equipped with an LCD screen to display the different thresholds in bargraph form. The test probes are removable and easy to replace. There is an integral compartment built into the instrument to store the probes.
