The Milwaukee® auto voltage/continuity tester combines the features you get from high performance electrical meters into an accurate, simple and productive tester. While traditional testers only indicate broad voltage ranges that mask electrical issues like voltage drops, the Milwaukee® auto voltage/continuity tester delivers measurements down to the decimal and displays them on an easy to read LCD. The tester also automatically determines whether to test for voltage or continuity and is compatible with common threaded carrying and mounting accessories like belt clips and magnets. The LED work light provides visibility in low-lit areas and test lead holders conveniently store the probes for when the job is done. This auto voltage/continuity tester is the ideal tester for use on outlets, switches, wires and breaker panels; perfect for any residential, apprentice or journeymen electrician looking for an accurate, simple and productive tester at an affordable price.
