After  one year i have switched on the 34970A DMM and I got the following error messages:
742 Cal data lost: DCV corrections
743 Cal data lost: DCI corrections
744 Cal data lost: RES corrections
745 Cal data lost: FRES corrections
746 Cal data lost: AC corrections
and sometimes
749 DMM relay count data lost
I would like to know if this is due to the internal battery or I simply need to redo a calibration.
If is due to the battery, do I need to return the instrument to Keysight or I can do by myself simply ordering a new battery to Keysight ?
