Pump Pressure Sensor (Code C1 and C2)
The program for the pump pressure sensor(s) is self-calibrating. There are no
adjustments that can be made to the sensors. When the calibration program is activated
the signal from the sensor(s) is assumed to be 0 PSI.
Note: If there is pressure in the plumbing where the sensor is mounted this
causes the program to be calibrated to a false 0. To prevent false zeroing,
drain the pump and plumbing to ensure there is no residual pressure before
running the calibration procedure.
1. Apply power to the display module.
2. Enter the calibration password.
3. Scroll to code C1 D.PSI or C2 I.PSI.
4. Press the MENU button SET P=0? ashes.
5. Press the MENU button again to set at 0. D.PSI=0 or I.PSI=0 ashes.
6. Press and hold the SILENCE button for 3 seconds to save the setting
into memory.
7. Press the SILENCE button when the program (C) code is ashing to exit
calibration. Press the MENU button to enter the next program. Press the
PRESSURE or RPM buttons to scroll through program codes.

2. Enter the calibration password.
3. Scroll to code C3 CAL. ENG RPM.
4. Press the MENU button to show SET RPM.
Result: Flashing digit is ready to be changed.
5. Set the RPM to match the reference RPM. Press the PRESSURE or RPM
buttons to change the value. Press the MENU button to change the digit.
6. Press the SILENCE button to save the setting into memory.
