Calibration without pressure:
Zero :
• Here a pressure value within the nominal pressure range of the transmitter must be
entered.
Span :
• Here a pressure value for the span within the nominal pressure range of the trans-
mitter must be entered.
Nominal pressure range:
Here the sensor’s pressure range is displayed
When calibrating without pressure (dry calibration), a sensor mounting
correction should be carried out before or after the calibration (see also
chapter 10.2.7 ). For this, the sensor must be placed in the reference
position for the measurement (mounting position) and must not be
under pressure.
When calibrating with pressure (wet calibration), the mounting correc-
tion is unnecessary, or it must be carried out before the zero point and
end of span are saved.
