Rigol DM3068 Calibration

(1/6) > >>

slugrustle:
Has anyone here had their Rigol DM3068 bench DMM calibrated?  If so, did you send it back to Rigol or have it calibrated at a 3rd party lab?  How much did it cost?

I was surprised to find the following statements in the service guide:


--- Quote ---To ensure accuracy, the meter should be completely recalibrated when the interval is reached whatever interval is chosen. Even though the meter has passed the performance test, the specifications (see “Specifications”) cannot be guaranteed unless recalibration is done.
--- End quote ---


--- Quote ---As the DM3068 does not support user calibration, please send your meter back to us for professional calibration when necessary.
--- End quote ---

That's easy: Choose a longer interval!  :)

Do you want (a) "calibration", ie. a report on it's accuracy at the moment, or (b) "adjustment", ie. tweak it as needed to improve accuracy?

The service guide also says

--- Quote ---An interval higher than 1 year is not recommended under all circumstances.
--- End quote ---

Based on the earlier quoted statements, what the manual refers to as recalibration, you seem to be referring to as adjustment.

Edit: What I'm really after is other's experiences with having this unit calibrated, whether by sending it to Rigol or to a 3rd party lab.  For example, perhaps the 3rd party lab read the service manual and said, "we can't calibrate this device."

"Adjustment" is the correct term.

Pricing and who can do it will depend on whether you want calibration or adjustment.

Almost any lab can do calibration. Not all of them will be able to do adjustment of every single multimeter on the market.

If you want adjustment you might end up sending it to Rigol.

tautech:
Please get the terminology correct.
Performance verification is the first part of calibration and if the instrument passes, that is it is found to be within manufacturers spec, it is then declared calibrated and documentation proving such is made that also lists the equipment used, their SN#'s and their calibration expiry dates.

OTHO if it fails, then adjustment may be required and much modern equipment requires a universal calibrator controlled by a PC script to automatically check accuracy and make the SW adjustments.
Some Cal labs have such equipment and the manufacturers calibration script however those that don't have access to scripts can write their own providing they have adequately trained and capable staff.
