To self-calibrate a board using NI-DMM, all you need to do is:
Be aware that your board's external calibration is expired, so running self cal will not get it to specification, and may or may not succeed at all. I suspect you will get the same error you got in MAX. I recommend you find a service to perform external calibration on your instrument.

No. To be within specs the DMM needs to be externally calibrated before the calibration expires. Self calibration is recommended to be run more frequently, I believe daily. And the board should be warmed up when you run it by powering it up for a while.
