The Calibrate Pressure Span screen allows the user to view and set the
pressure sensor calibration span point.
Note The plumbing going to the pressure sensor should be disconnected so
the sensor is reading ambient pressure before performing the span
calibration. The operator should use an independent barometer to measure
the ambient pressure and enter the value on this screen before
calibrating.
In the Main Menu, choose Service > Pressure Calibration > Span.
