Note!
• The Cerabar S and the Deltabar S are configured for the pressure measuring mode as standard.
The Deltapilot S is configured for the level measuring mode as standard. The measuring range and
the unit in which the measured value is transmitted, as well as the digital output value of the
Analog Input Block OUT, correspond to the data on the nameplate.
• See also Operating Instructions BA00301P Deltabar S, "Pressure measurement" section or
Operating Instructions BA00302P Cerabar S, "Pressure measurement" section or BA00372P
Deltapilot S, "Level measurement" section.
• For a description of the parameters mentioned, see

Note!
• You can select another pressure unit by means of the Calibration Units/CAL_UNIT parameter
(→ ä 54). You can also specify a customer-specific unit by means of this parameter.

Description
1 Deltabar S: Before configuring the device for your
application, the pressure piping must be cleaned and the
device filled with fluid. See Operating Instructions
BA00301P.
P01-PMD75xxx-19-xx-xx-xx-000
2 Open the Pressure Transducer Block and set the block
mode to OOS.
3 Carry out position adjustment if necessary.
The following options are available for performing position
adjustment:
• By means of the parameters
– Pos.Zero Adjust/ZERO_POSITION_ADJUST
(→ ä 59) or
– Pos. Input Value/POSITION_INPUT_VALUE
(→ ä 59) or
– Calib. Offset/CALIBRATION_OFFSET (→ ä 59).
4 Select the measuring mode if necessary:
• Select the "No linearization" option by means of the
Linearization/LINEARIZATION parameter.
• Select the "Differential pressure", Gauge pressure" or
"Absolute pressure" option by means of the Primary
Value Typ/PRIMARY_VALUE_TYPE parameter.
5 Set the Pressure Transducer Block to the "Auto" block
mode.
6 Where necessary, configure the Channel/CHANNEL
(→ ä 96), Linearization Type/L_TYPE (→ ä 97),
Transducer Scale/XD_SCALE (→ ä 95) and Output
Scale/OUT_SCALE (→ ä 96) parameters by means of the
Analog Input Block.
