I was looking at the Kewtech KT1780 voltage tester in toolstation, when I see the TIS 851 that is self proving and wondered if anyone used one and they are any good.

I seem to remember that those so called self test jobbies only test the electronics within the tester, could be wrong though, I always use a PU

I am a diy'er so it is not worth buying top of the range tools, but would rather use a decent tester even with the power off to be sure.

Might seem to have been worth using the proper tools if you find yourself attached to something that has 230Volts in it and you can't let go.

I agree Pete and would add that branding this "self proving" is somewhat ambiguous and could be misleading to its target market. It appears all it is doing is showing all the LEDs light up when the probes are touched together for a couple of seconds (the Fluke T130 & others also do this, however the manufacturer doesn't deem them "self proving") Rather different to proving it at 230V etc.

It's not even particularly cheap - spend a bit extra and get a Fluke.

I see nothing wrong with it.

Just prove it works on something you know is live before hand.

No TIS gear I have used today is up to day to day professional use and has a cheap feel to it but if it is for DIY it is more than enough for your needs I would say

I have to give you a disagree Matthew, solely for the statement that you agree it cheap looking, but OK for DIY, I would say that a DIYer using cheap test gear makes it even more of a danger, no offence meant.

I've a TIS clamp meter, it does it's job pretty well.

I know it's not going to take as much abuse as more expensive versions, but treat it with a bit of care an it's done me ok the past few years as a cheap carry around that I'm not afraid to loose or get stolen.

What I mean is although it is functional from what I have seen it isn't up to day to day use and going in and out of the toolbox over and over and I don't think it could take a few bumps along the way

I personally thought the proving part was about providing enough energy to prove IR at 200V ish volts ..without overdoing it ...
(Like harming operator--If fatally flawed)
If you tried a neon screwdriver full of salt water...
you would "Know" something was wrong !!!
--NEONS are dangerous--
