The “Special” calibration mode is used to set up system
parameters that rarely need to be changed or adjusted. To
enter Special Cal, put the system in HOLD, turn the console
OFF, press and hold both the RUN/HOLD button and CAL
button while turning console ON. The console will display
SPEC for 2 seconds to show that the console is in the Special
Calibration mode. Release the RUN/HOLD and CAL buttons.
The CAL icon and Warn LED will turn on. The desired Special
Calibration parameter(s) can then be accessed with the rotary
switch per the illustration below. To exit Special Calibration,
press and hold the CAL button for 2 seconds. The console
will store any changes and revert to normal operation.
NOTE: you must exit Special Calibration to save changes.
The following table describes the special cal parameters and
shows the factory settings. More detailed descriptions follow

HOLd/FILL:
“HOLd” selects normal sprayer monitor mode,
“FILL” selects batch mode for filling tanks at a depot. The
selection of HOLd or FILL mode affects both the way the
control output operates and the way the
counters operate. Use “+” and “-” buttons
to select between
HOLd and FILL modes.
In HOLd mode, the
Control Output can be
used to open or close a valve based on the RUN/HOLD status.
If the system is in RUN, the Control Output turns ON, if in
HOLD, it will turn OFF. If set in the HOLd mode, the TANK
display will show the amount remaining in the tank and the
TANK ALARM will work as described on pages 19 & 27. In
FILL mode, the optional Control Output energizes when the
console is changed from HOLD to RUN mode and remains
energized until total flow equal to TANK VOL is reached,
then it is de-energized. This may be used to fill the tanks at a
depot or batching operation. It is not recommended to use
the FILL mode at all if operating the system in typical sprayer
monitor applications.
