Wow, I know have a fully functioning meter that not only checks out against my calibrator but even more importantly agrees with my other meters give or take the odd least significant digit by 1 or 2 counts as these are often bouncing around due to noise etc, I'm not at all bothered by that
Thanks to bd139 for his assistance and no I don't think I'll bother getting this checked over by any other Lab because I doubt its going to be worth it and also of course apart from RS the only other lab remotely near me is Calmet, who say that can do it but it is not known to how many digits, unless bd139 does as he spoke to them? I have personally spoken to quite a few labs, many declined because they could not do it, and there was 3 others that claimed that they could calibrate it to either 2 or 3 digits and if I wanted 4 digits, then 1 on those said that they could farm it out a sister company but none said they could do a full 5 digit cal.
Should I email the lab that returned it uncalibrated and FOC because they couldn't get it to retain the calibration and tell them that what they couldn't do I've managed to do?
