Kewtech KEWPROVE3 690V AC/DC Proving Unit
 
A proving unit is essential for proving circuits are dead before commencing work. The high output will drive low impedance testers such as traditional test lamps as well as modern two pole testers – the one to have to be confident that it will work with your tester. It even steps down through the voltage stages to prove each stage as well
