After the password has been entered the SETUP Service screen allows access to the

Calibrate, Seal Point, Linerize, and Adaptation screens.

Consult factory before changing any Seal Point, Linerization or Adaptation

parameters.

Press the [CALIBRATE] key to access the calibrate screen, "Figure - Calibrate Data".

The Calibrate screen contains three tabs: DATA, EDIT AND CALIBRATE. When entering the

calibrate screen the first time the Data Screen is the default. The Data screen allows changes

to be made to the Zero, Span, Date of calibration and displays the sensor reading.

The screen accessed by pressing the [EDIT] Tab, "Figure - Calibration Edit", allows calibra-

tion using data available from a previous calibration. An example of this is when an As-Found

calibration is performed and the applied and measured pressures from the calibration are

available. The low true pressure should be less than 20 %FS and the high true pressure

should be greater than 80 %FS for best results. To edit the calibration from known data, enter

the applied pressures in the Desired column and the measured pressures in the Actual column

by pressing the number to be adjusted. When the values are changed, a new key “APPLY” will

appear on the screen. Press the Apply key to save the calibration data.
