Can anyone help me out here? I've just looked at the Calibration Cert for my multimeter. Although I purchased the meter last September (08), the calibration date is November 07. I first used the meter on a (non-part P) job in February this year, so I'm guessing that's what counts as the Commissioning date. First question is ........ does it need to be re-calibrated a year from the old Calibration Date or from the Commissioning Date? Second question .... where does it go to be re-calibrated and how long and how much?

Many thanks in advance.

If you are registered with NICEIC etc and they ask to see your current and previous certificate I think you will find that they dont care when it was first used. As for costs they vary from about £30 to £90 depending on what you have and where you go. Its best to google it and go to the closest to you. Something like megger calibration should do the trick

i would get it calibrated again now and it will save any trouble later with cirts
a megger multi functiion mft 1552 costs about 60 quid through newey and eyre and i think seperates are 25 each

Hi,

I was told by an NICEIC inspector that as long as you keep an

accurate record of 'continuing accuracy' then there is no need to

calibrate your meter (ever) - as long as the readings don't drift, of course.

Save you some money that way:)

Cheers

Hi sixfingers,

Yeh, the bloke I spoke to said it also depends on usage and how

you look after it eg. thrown in the back of the van etc. but he

did say that as long as the readings remained constant then that was fine.

If you send a meter for calibration that doesn't need it you're just paying

them £80 to perform the checks that you are already doing yourself.

Cheers

hi wayne,
my nic assessor who is also an approved contractor told me it has been 6 years since he had his meters calibrated as his monthly test record has stayed constant. makes sense really ;)

Thanks very much guys for a good range of answers, really helpful. I've done two monthly checks on it and the readings are constant. I'm panicking because I've got my NIC (much delayed) first assessment coming up soon. I think I will have a look at the guy who does it on site anyway. Thanks again.

Have to say, i think the monthly check is a good idea but i would still get it properly calibrated at least every couple of years or so for peace of mind and for the records.

After all, the serial numbers are referenced on the certs.
 
Mine go in every year regardless.;)
so did mine lenny. gonna spend the money on something more useful now though ;)
