The calibration procedure is to be done only at a single point, which is the normal
operating pressure of the engine.
Connect a temporary engine mounted pressure gauge of suitable accuracy and
start the engine. Once 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 pushbuttons to adjust the correction factor
number while observing the displayed pressure on the MEC 2. 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 pushbutton to accept the
correction factor number. Record the correction factor number on the MEC 2
programming sheet for future reference.
