It's possible to backup the calibration data so that the battery can be replaced. Here's a program for the 71B.

As your DMM isn't reporting any issues during the power-on self test that means the CAL RAM battery is still good. If the battery fails the DMM will revert to default calibration factors.

Is there any way to back up this data using an HP-41?
