3. Start driving toward the start point of the 300 foot / 100 meter
course.
4.
As the starting point is crossed, press the PLUS
button
once to begin the calibration process. The 845 will count the
Pulses generated while the course is driven.
5.
As the ending point is crossed, press the PLUS
button
once. The number displayed on the screen is the speed
calibration number.
6.
To accept the value, press the PROGRAM
button. To edit
the value, use the PLUS button or MINUS
buttons.
The number of Pulses is automatically stored as the new
calibration.
*To confirm Automatic Speed Calibration distance, first complete
the calibration procedure. Advance to the Distance Counter step.
Drive the vehicle across the same 300 foot / 100 Meters course,
turning the Master Switch “ON” at the starting point and “OFF”
at the finish point. The distance measured should be 300 feet /
100 Meters (+/- 6 feet/+/- 1.8 Meters).
Figure 3-5: Speed Sensor Automatic Calibration
NOTE: When the Automatic Calibration Mode is activated, no other
functions are possible until the console receives Pulses for
calibration. To deactivate the Automatic Calibration Mode,
press the PLUS
button until a number is displayed.
Distance Counter
The Distance Counter step is not a calibration step. It is a help
function that can be used to measure a distance such as to confirm
Automatic Speed Calibration. No value can be entered here. This
feature measures distance in feet/Meters.
When using this function all section switches must be set to off to
avoid spraying.
1. Turn Master Switch on to start distance counter.
2. Drive the desired distance.
3.
Turn Master Switch off to stop distance counter.
To clear an existing distance value, press and hold the PLUS
and MINUS buttons simultaneously for 3 seconds.

Pressure Sensor Installed
Select if a pressure sensor is installed.
If a flow sensor is not installed, this step is automatically set to
“Yes” and cannot be changed.

Zero Pressure Reference
This step is only available if “Pressure Sensor Installed” is set to
“Yes”.
The Zero Pressure Reference is used to calibrate the zero pressure
setting of the pressure sensor installed on the system. The
pressure sensor used with the console is a current type sensor and
uses a 4-20 mA reading. “4.0 mA” represents “zero” pressure.
1.
If necessary, run the Automatic Calibration to determine the
Zero Pressure Reference setting.
2. Enter the value for the Zero Pressure Reference setting.
