Sensor Calibration
The following sections will describe the various methods available to
calibrate the level sensor. For all calibrations, the button(s) must be held for
5 seconds in order to be recognized. For best results, the unit should be at
application temperature when calibration is performed.
The sensor also detects if the calibration is done out of sequence. For
example, if a full calibration is attempted before an empty calibration was
performed, then the calibration is ignored and the STATUS and LOW LEDs
on the circuit board will turn red for 5 seconds after attempting the calibration
indicating a bad calibration attempt.
The unit can also report the last calibration successfully performed. If the
ENABLE and RESET buttons on the front panel are held simultaneously, the
panel LEDs will illuminate to indicate the last calibration. An illuminated
green Enable LED indicates that a basic (empty level) calibration was
performed and an illuminated blue FILLING LED indicates that a precision
(full level) calibration was performed.
Two levels are stored in nonvolatile memory, the calibrated empty point and
the calibrated full point. The level at which the unit fills to is computed based
on the empty and full calibration points
Calibration Summary
The table below summarizes the different types of calibration available. The
different calibrations should be performed in the specific order shown below.

Full point is set to a predetermined level above
empty that is suitable for a wide range of
adhesives. This is the only calibration that most
units will require.

the full. Use this calibration (after an empty
calibration) to provide more precise level
control than an empty calibration alone
