Calibration

Resetting the calibration password
If you lose the calibration password, you can unlock calibration by shorting together the
CAL pads which are located on the display board. Doing so will also reset the password to
the factory default (002500, front panel; KI002500, remote).
See Section 5 for details on disassembling the unit to access the CAL pads. Refer to the
display board component layout drawing at the end of Section 6 for the location of the
CAL pads.
Viewing calibration dates and calibration count
When calibration is locked, only the UNLOCK and VIEW-DATES selections will be
accessible in the calibration menu. To view calibration dates and calibration count at any
time:
1.
From normal display, press MENU, select CAL, and then press ENTER. The unit
will display the following:
CALIBRATION
UNLOCK EXECUTE VIEW-DATES
2.

next and last calibration dates and the calibration count as in the following
example:
