4 Performance Tests and Calibration
Aborting a Calibration in Progress
Sometimes it may be necessary to abort a calibration after
the procedure has already been initiated. You can abort a
calibration at any time by pressing:
The calibration will be aborted, the primary display will
show FAIL and Error 705, CAL Aborted will occur.
Shift
CAUTION
If you abort a calibration in progress when the instrument is attempting
to write new calibration constants to EEPROM, you may lose all
calibration constants for the function. Typically, upon re–applying power,
the instrument will report error 742 through 748 (whichever is applicable).
If this occurs, you should not use the instrument until a complete
re–adjustment has been performed. A list of the possible calibration errors
is given on page 110.
