Recently I bought an old NI C-series module, it was sealed and new.
but because it was manufactured 5 years ago I tested it and it was ok and measured data precisely. (I guess it has been manufactured 5 years ago because the calibration date was for that time).

So I wanted to update the calibration date (the calibration date that shows on NI-MAX). I searched on net and find out it's possible to renew the calibration date without adjust calibration.

I used attached VI for this purpose. I hoped it can help if you have same need.
best regards
