I planned to reformat one of our machine and if possible i want to backup the calibration file/data of PXIe-4081 DMM so we don't need re-calibrate it again after reformat. Is there's a way to do this? Thanks.
The calibration constants are stored on a flash memory on the instrument. You can wipe your hard drive clean and/or move the instrument to another system, calibration constants are preserved.
Do note that in order to meet the documented specifications for the device you need to run self-calibration in the last 24 hours after the device has been powered up for 60 minutes on the system it will be used in.
