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 checking proving through the entire range
• The first proving unit with a true AC output
• Battery low inidcation to ensure an engineer is never caught out
• Compact desigh
• Proving unit terninals 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 entre range
• Non-contact voltage proving pad for quick and safe proving of NCVD
