Professional Proving Unit With Volt Detector Test
- Proves two-pole testers, multimeters, test lamps and single-pole testers
- Ramps up to 690V then slowly decays for checkingproving through the entire range
- The first proving unit with a true AC output
- Battery low indication to ensure an engineer is never caught out
- Compact design
- Proving unit terminals become closed circuit at the end of the test cycle to prove the continuity setting on some two pole testers
- Slower ramp-up to 690v so ensuring ultimate confidence that the tester is being proven throughout the entire range
- Non-contact voltage proving pad for quick and safe proving of NCVD
