Calibrations

Calibrations establishes either manual or automatic
settings of the sensors.
NOTE: For specific calibration options to appear, a
specific sensor needs to be installed. Sensor
availability is activated on the Sensor Presence
screen in the OEM section.
Pulses Per Volume
Pulses Per Volume establishes number of pulses for one
(1) cubic foot or one (1) cubic centimeter. This value can
be established manually or calibrated automatically. Each
type of spreader has a variety of variables that factor
into the pulses per volume number (roller diameter, gate
height and width, sensor type, type of belt or chain, etc.).
The pulses per volume number factors these variables
into the spreader output
Note: The calibration is based on the Reference Gate
Height, which defaults to 4 inches / 10 cm. This
number is accessed in the OEM Menu. The actual
Gate Height during calibration MUST match the
reference gate height setting.
Manual Calibration
Manual calibration establishes the pulses based on a user
entered value.
• To select the Pulses per Volume, use the number
pad or slide bar.
Automatic Calibration
Automatic calibration establishes the pulses using the
automatic calibration function.
• To calibrate the pulses per volume, select
CALIBRATION KEY .
• Follow the series of instructions displayed.
NOTE: Material will be dispensed during this procedure.
Be sure that a collection device is in place so that
a proper volume can be determined.
