Test equipment calibration

[Rich-B]

Hi all. I was wondering what you guys do when it comes to calibrating your testers. Do you send them away or do you use a calibration box or another method entirely?

Just lost the use of both of mine, they are away, dropped them of myself and pick them up in two days. How will i manage with just a clamp meter and voltage tester :-(

Eitherway you will need them professionally callibrated. Check boxes are not callibration equipment. They only provide accuracy checks for you over the year(callibration period being 12months). Saves u potentially going back over months of testing if your meter has become faulty. E.g dropped out of an attic space for instance!!!

I always use on site calibration services OSCS and I keep a back up test set.Also useful if your gear gets nicked.

The scam bloke said to me you can send your tester for calibration every 3 years but you need a checkbox to check readings on testers every month (yeh right!!!)
So now your checkbox needs calibrating every year (what's the point to it all)

yes every 12 months most wholesalers will get it calibrated for you back in a cou[ple of days about £40

me too. he comes to you, so there's no down time and no carriage costs.

because some outfits will have several MFTs on the go........not to mention seperates (low resistance ohmmeters, high ohmmeters, loop testers, RCD testers)..then theres your other stuff such as a multimeter...certain clamps etc....so if you have quite a bit of stuff....all of a sudden a checkbox looks viable....

i assume he brings the call rig to site?...if so how is the instrument expected to `normalise`?.....callibration houses are climate controlled environments and test equipment is left to `settle` for 24 hours before its put on the rig....

Thanks for all the advice guy, I will calibrate via a service company.
