Calibration
Before attempting to calibrate, make sure you have the proper
equipment called for in each procedure.

Entering the Calibration Menu

Enter the Calibration Menu to change the configuration of the dFL (default
language) parameter. Several parameters are dependent on the dFL parameter,
they are listed below. It is a good idea to change this parameter, if necessary,
before entering the Setup menu. The factory configures your unit to your
preference, but can be changed at any time.
In the Calibration menu, various input signals must also be supplied in order for the
control to go through its auto calibration. The calibration menu can only be entered
from the LOC parameter in the Setup menu. Press the UP/DOWN keys
simultaneously for 3 seconds (± 1 second). The CAL parameter appears in the
lower display with "no" in the upper display.
Any inadvertent change in the displayed data, when pressing the UP/DOWN keys,
is ignored. Calibration values are not retained unless you are in the MANUAL
mode. Press the UP/DOWN keys to change the upper display to "YES." Press the
MODE key to enter the calibration sequence.
