Safe Isolation Guidelines.......they Are There For A Reason

[kerching]

So ended up working this afternoon
I DO NOT work saturdays unless there is large coin involved

fluke T 150 tester out ( this is the dogs back wheels, seriously )
Check testers.....tips together...givenit about 15 seconds....all display lights up...all leds light up

Test supply.........DEAD


Test testers again......dead as Jimmy savile!


WTF ! Testers have gone faulty between TEST ISOLATE TEST

Not happy....but I think they are under warranty

So, out with the spare set until Megger Mark contacts me in reply to my email


JUST.....be careful,out there



And yes...the supply WAS live.....and so am I

 

[Sharpend]

You mean the batteries have gone dead!?

Just examining!!!

I think we can all get blaise'  on safety and warnings from others can bring us back to earth  ( As in the planet not the ...well you know what I mean....) 

One reason I don't condemn Voltsticks & Neons is that they are yet another line of defence .  I've received one bad shock in my time and I don't recommend it one bit .

I still use the old Drummonds as  back ups  on nasty stuff.

I don't know that particular tester inside out. But surely putting the tips together just tests that the continuity function is working. Not really testing the voltage detection function. This is when you should test on a known good supply so that you know the actual function of the tester you are relying on is working correctly.

Or a proving unit, as said putting the probes together only proves that you have continuity not that it illuminates with a voltage. That's why you should check that it illuminates on a known source before and after testing for dead.

Never had an issue with my T5 but like Deke says I have a voltstick to hand as a last line of defence  

 

[ProDave]

I simply never touch anything that my neon has not touched first.

I threw a volt stick away because it did not always show a live cable. I never trust one of those. Handy for proving something is live and a bit of fault finding but never never never for proving something is dead.

Sorry...my mistake.....on reading my post back some bits got deleted and i had not spotted it. Mr Merlot is to blame

I did test them with my Seaward Proving Unit....all was fine

Re-checked and all was not well

The T150 will indicate a voltage even if the batteries are flat

Later on I checked the batteries and they were fine

Then tester started being weird. ....only showed continuity when the load buttons were pressed....then only did this once....torch function works fine. All a bit odd, so it is off back to Mark

Mr Kerching you have now had a reply  :Salute

The unit should always be checked with a proving unit, good ones already pointed out by the very kind (thanks for the links) Conoeboy.

Please check out this volt Alert, we have sold a great deal of them in the last month or so....  http://isswww.co.uk/flir-vp52-non-contact-voltage-detector-and-flashlight

If anyone should care to purchase a proving unit i would be very happy to sort out a forum special price

I got one of them Megger proving units that Canoe is on about, and, as he says, it is very nice indeed!!

john..

I have fluke LVD2 - really like it, becuase  it is also torch it's very rarely not in my pocket

Exactly right mate all the so called self test testers only test the electronics of the tester, thats why everyone needs a proving unit
