- Proves two pole testers, multimeters, test lamps and single pole
testers
- Ramps up to 690V then slowly decays for checking proving
through the entire range
- The first proving unit with a true AC output
- Battery low inidcation to ensure and 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
- Battery powered : 6 AA (R06 / LR06)
