Read Pressure
Choose this function to measure pressure in one of 15 different
engineering units using a Crystal Multical Pressure Module.
1) Move the power switch w to READ then Double Click the
EZ-DIAL knob to get into the Double Click Menu. Turn the knob

The following screen will appear each time pressure is selected
to remind you that the switch on the Multical Pressure Module
MUST be set to PSI for the PIE 820-ELITE to indicate the correct
pressure. Failure to do so will result in the wrong pressure being
indicated and possible damage to the pressure module.
2) Connect the electrical output of the pressure module to the
mV inputs of the PIE 820-ELITE matching polarity.
