Take a look at this, and see if it helps (different types of calibrations). ;) http://www.keithley.com/services/calibration |

It sounds like there are two separate issues here: First, the OP got back his DMM with an "UNCALIBRATED" error. Second, it sounds like he didn't understand the different levels of calibration services available? On the first, I'd ask the lab to explain how they were able to calibrate with this error, or what they could have done that generated it. On the second, if the data is important to you, then you can see if it was recorded and you can pay the difference to get it. |

If it was broken before it was sent then they won't touch it. But they should have reported that back to you at least. |

Philips (Australia) used to do a fixed price repair/calibration on Fluke 77 meters & the like, back in the day. A good deal if your meter was faulty,& still reasonable if it just needed calibration. Probably too expensive for a calibration lab these days. |
