best voltage tester

Hi Trypod , although you say depends who you are with I still thought you needed a valid calibration cert for joining a part p scheme . I have a megger 1553 and I'm thinking of getting it re calibrated due to cert running out . looking to sign up with elecsa.

 

[trypod]

Calibration certificates do not run out

When you buy a new meter from Megger it may have been calibrated three months before you got it there is a box on their certificated for activation date.

Most suppliers recommend 12 months however it may only have been used five times in that time that is why you need to keep records of checks and use.

Problem is Kev I've never used it, and it's now over a year old.

 

[eskimo39]

Eh tell me if I'm wrong but do you still not need to calibrate your multlifunction tester or seperate's and have a valid certificate each year?

I thought you had to have annual calibrations done with any scheme, the check boxes etc are just a good way to verify the consistancy of your readings throughout the year.

I recently joined Napit and the inspector said that as long as we had a method in place for proving the readings were consistant ie check box / dedicated socket on a monthly basis then there was no need to have the meter recalibrated. He added that when the readings start to differ thats when calibration is needed.

hi trypod,
in your post to everyone about the calibration cert my cert was dated jan2009 and i only got the megger in august. i have not filled in the date on the cert for activation date as since the course i have not used it instructor on the course told us when we start self employed or working and started to use it then fill in the activation date is this correct.this is why i was asking about the testing calibration on a known socket and checkbox to prove calibration should i fill in the date from the course or when i get going sorry mate if i asking stupid questions just want to get everything right i have a socket near c.c.u. so i will use this for testing purposes is that ok cheers mate

 

[trypod]

That's fine
Date of activation I would put the date you start using it for work

 

[brucelee]

cheers mate,
i was thinking as its a year ago since it was calibrated as new that i would have to get it re-calibrated so as soon as i start to use it for work i will date it thanks kev do the calcards come with idiot proof instructions haha cheers

 

[trypod]

they should do

 

[dufjax]

dufjax are the cal cards any good and are they easy to use mate

I've no idea I keep meaning to buy one.

I think I also read somewhere that Elecsa will accept you using the Cal Card (and recording the values, once a month) instead of getting your tester calibrated.

thanks kev,
i got the test sheet cheers mate

The Fluke T series are nice kit, but with an input impedance of 1M (same as some DMMs) and not being GS38 compliant, I can't see how it can be used for safe isolation.
The Fluke T100 series are nice, but a PITA as they trip RCDs. The Fluke instructions of L-N before L-E is cobblers, doesn't always work.

hi switchmaster
when you say the t series are not gs38 compliant which models are you referring to as i have just purchased a fluke T5-1000 and in fluke catologue i received this morning they say they are supplied with GS 38 compliant tp4 4mm detachable probes do you mean the t50,t100,t120 and t140 as in the catologue it doesnt state these models are compliant

 

[Guest123]

Yes, it's the ones with the ridiculous amount of exposed probe tip showing, not far off 20mm I think.

 

[sw1tchmaster]

None of the T5 series I have seen have been GS38 compliant, maybe that has changed recently. All that I've seen have had damn near an inch of bare prod exposed, like Lenny says!

In any case, I wouldn't trust a T5-anything for safe isolation as it's a high-impedance instrument.

cheers lenny,trypod& switchmaster
the t5-1000 i got are gs 38 compliant only got them jan 4th checked first as this is why i put this post up what do you recommend instead cheers to all for useful advice as i was going to buy t 140 but after advice from posts above chose t5 -1000

so if i buy a calcard and record the values in a log every month i don't need to get my MFT calibrated every year and i can just show my assessor(elecsa) this log and he'll be happy with it for 3 years?
if this is true then i could save 2 years calibration charges (£80) and all i'd have to do is buy a calcard for £25 and check once a month

Hi ExArmy, In my experience, it depends upon your assessor and whether he's happy to see a log you've kept.

Other electricians I've spoken to like to use a mechanically and electrically sound circuit at home to do a whole range of regular tests upon, and then keep these logged. This way, you're proving most of the test functions on an MFT, rather than just insulation resistance and continuity ranges.
