Just received my HP3478A back from TEKTRONIX calibration lab and the unit says "UNCALIBRATED"??. I have doubts they properly calibrate this DMM. Calibration equipment used: FLUKE 5700A & FLUKE 5522A. Tektronix doesn't even have their own calibration instruments? I am disappointed. :o :-- |

Tek never made any calibrators. Fluke and Wavetek. They may have forgotten to flick the CAL switch back .... |
| vk6zgo:
Maybe not for DMMs,but they certainly made them for Oscilloscopes! |
| IvoS:
TEKTRONIX gave me a calibration certificate even though the ohm scale wasn't calibrated at all. I just lost 3 weeks of my time hoping for this unit to come back calibrated. This is a bad experience for me with Tektronix and I will never buy anything that says Tektronix. They suck. They have balls not even tell me that it couldn't be calibrated for some reason. They are probably hoping that I will never find out because I sent it there as a person, not a company. :-- It was Tektronix in Mass, Billerica. They suck. :-- |

What did Tek send you? Calibration usually does not include any adjustments (see Dave's video blogs on calibration). Did you get a report on the errors on each range? Are you saying they didn't test resistance ranges at all? Richard. |
