POS. ZERO ADJUST
Entry
Position adjustment – the pressure difference between zero (set point) and the measured
pressure need not be known. (A reference pressure is present at the device.)
Due to the orientation of the device, there may be a shift in the measured value, i.e. when
the container is empty, the MEASURED VALUE parameter does not display zero.
Example:
– MEASURED VALUE = 2.2 mbar
– 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 CALIB. OFFSET parameter displays the resulting pressure difference (offset) by which
the MEASURED VALUE was corrected.

MAX. FLOW
Entry
Enter maximum flow of primary device.
See also layout sheet of primary device. The maximum flow is assigned to the maximum
pressure which you enter via MAX PRESS. FLOW.
Factory setting:
1.0
MAX PRESS. FLOW
Entry
Enter maximum pressure of primary device.
→ See layout sheet of primary device. This value is assigned to the maximum flow value
(→ see MAX. FLOW).
Factory setting:
High sensor limit (→ See PRESS. SENS HILIM, Page 140)
DAMPING VALUE
Entry
Enter damping time (time constant τ).
The damping affects the speed at which all subsequent elements, such as the on-site
display, measured value and OUT value of the Analog Input Block react to a change in the
pressure.
Input range:
0.0...999.0 s
Factory setting:
2.0 s or as per order specifications
