Pos. zero adjust
Write permission Operators/Service engineers/Expert
Description Position adjustment – the pressure difference between zero (set point) and the measured
pressure need not be known.
Example • Measured value = 2.2 mbar (0.033 psi)
• You correct the measured value via the "Pos. zero adjust" parameter with the "Confirm"
option. i.e. This means that you are assigning the value 0.0 to the pressure present.
• Measured value (after position adjustment) = 0.0 mbar
• The current value is also corrected.
Options • Confirm
• Cancel
Factory setting Cancel
Calib. offset
Write permission Service engineers/Expert
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 use the "Calib. offset" parameter to correct the measured value with the value
entered, e.g. 2.2 mbar (0.033 psi). i.e. This means that you are assigning the value
980.0 (14.7 psi) to the pressure present.
• Measured value (after pos. zero adjust) = 980.0 mbar (14.7 psi)
• The current value is also corrected.
Factory setting 0.0
Damping
Write permission Operators/Service engineers/Expert
(if the "Damping" DIP switch is set to "on")
Description
Enter damping time (time constant t).
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 2.0 sec. or according to order specifications
