Engine Temperature & Oil Pressure Calibration

To accurately calibrate the controller’s temperature sensor, an external temporary engine mounted temperature gauge is required. The external temperature gauge should be connected as close as possible to the temperature sender.

To accurately calibrate the controller’s pressure sensor, an external temporary engine mounted pressure gauge is required. The external pressure gauge should be connected as close as possible to the pressure sender.

ENGINE TEMP

127 955C

Displays the type of calibration function.

Displays the calibration correction factor number (0-255) used to obtain the correct Temperature or Pressure reading. Displays the actual temperature or pressure measurement shown on the display menus.

This reading may be calibrated higher or lower by changing the correction factor number.

Engine Temperature The engine temperature analog circuit must be calibrated with the engine temperature sender mounted on the engine. Connect a temporary engine mounted temperature gauge of suitable accuracy and start the engine. After the engine reaches normal operating temperature, enter the programming mode and scroll to the •Engine Temperature Offset" calibration point. Use the INCREMENT or DECREMENT push-buttons to adjust the correction factor number while observing the displayed temperature. Adjust the correction factor number to obtain the identical temperature reading as measured with the external temperature gauge. With the correct temperature displayed, press the •Enter" push-button to accept the correction factor number. Record the correction factor on the programming sheet for future reference.

Oil Pressure		Connect a temporary engine mounted pressure gauge of suitable accuracy and start the engine. After the engine
		reaches normal operating pressure and temperature, enter the programming mode and scroll to the •Engine Pressure
		Offset" calibration point. Use the INCREMENT or DECREMENT push-buttons to adjust the correction factor number
		while observing the displayed pressure. Adjust the correction factor number to obtain the identical pressure reading as
		measured with the external pressure gauge. With the correct pressure displayed, press the •Enter• push-button to
		accept the correction factor. Record the correction factor on the programming sheet for future reference.
