Calibration

Fig. 3-1-31. This menu shows when the last complete check was made and when the next
calibration check is due. It also shows the date on which the individual items were adjusted. It is
possible to inspect the calibration value of these items but calibration cannot be carried out
unless the protection facility is unlocked at Level 2. Full details regarding calibration can be
found in the Service Manual.
