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
