No, I don't bother using a proving unit. I use a fluke volt stick tester and steinels to ensure power is off.

I not sure if sentiels comply even
,martindale voltage indicators have been used by electricity boards and throughout industry for decades ,there fused and the probe and robust lead instill confidence in using one
,the man asked for a recomendation ,i know which i would choose ,,

Martindale is good. One of the best. As for proving unit, you don't have to use one. Especially if you have to pay 3 times the price of the Voltage Indicator for one of them. But you must test it on a known live source to make sure it is working.

I suppose it's OK when you have the live incoming supply to prove the Voltage Indicator on ie. at the Consumer Unit, but in other situations it could be risky.

proving units are very useful

personally, at the top of a ladder, if i want to prove something dead, a proving unit is invaluable

The alternatives are: come down the ladder and find a live supply, or sod it and just crack on - of course you take the sod it option (and compromise your safety)

Just a quick question, how can you prove your tester on the incoming side of the consumer unit when the Electricity at Work Regs state that the front cover must never be removed unit power is isolated, ie, main fuse below pulled out? Therefore a proving unit must be used to complete safe isolation procedure on the consumer unit.

The proving unit works on the same principle as your insulation tester, to if you can not afford one, the use your insulation tester to prove your martindale tester works, set insulation tester to 250 V dc and clamp the test lead to the end of the voltage tester and press the button the apprioprate neons on tester will light up.;)

Personelly I always use the proving unit from martindales, another good reason for using martindale voltage indicators is that it does not cause nuisance tripping of RCD, unlike some other voltage indicator can.

How do you measure Ze if you can't have the cover off and power to the incomming side?

Never used a proving unit personally, apart from my 2391 exam.
