Example • Measured value = 2.2 mbar (0.033 psi)
• You correct the measured value via the "Pos. zero adjust" parameter with the "Confirm"
option. This means that you are assigning the value 0.0 to the pressure present.
• Measured value (after pos. zero adjust) = 0.0 mbar
• The current value is also corrected.
Factory setting Cancel

Description Position adjustment – the pressure difference between the set point and the measured
pressure must be known.
Example • Measured value = 982.2 mbar (14.73 psi)
• You correct the measured value with the value entered, e.g. 2.2 mbar (0.033 psi) via the
"Calib. offset" parameter. This means that you are assigning the value
980 mbar (14.7 psi) to the pressure present.
• Measured value (after pos. zero adjustment) = 980 mbar (14.7 psi)
• The current value is also corrected.
Factory setting 0.0
9.7 Configuring the damping
The output signal follows measured value changes with the delay time. This can be
configured via the operating menu.

(if the "Damping" DIP switch is set to "on")
Description
Enter damping time (time constant
t
) ("Damping" DIP switch set to "on")
Display damping time (time constant
t
) ("Damping" DIP switch set to "off").
The damping affects the speed at which the measured value reacts to changes in pressure.
Input range 0.0 to 999.0 s
Factory setting 2 s or according to order specifications
