Function group POSITION ADJUSTMENT
SET LRV (245)
Entry
Set lower range value – without reference pressure.
Enter pressure value for the lower current value (4 mA).
Factory setting:
0.0 or as per order specifications
SET URV (246)
Entry
Set upper range value – without reference pressure.
Enter pressure value for the upper current value (20 mA).
Factory setting:
High sensor limit (
see PRESS. SENS HILIM, Page 28) or as per order specifications
DAMPING VALUE (247)
Entry
Enter damping time (time constant
).
The damping affects the speed at which all subsequent elements, such as the onsite
display, measured value and current output react to a change in the pressure.
Input range:
0.0 to 999.0 s
Factory setting:
2.0 s or as per order specifications

Description
Due to the orientation of the device, there may be a shift in the measured value, i.e. when the container is empty or
partially filled, the measured value does not display zero. Cerabar S provides two different options for carrying out
position adjustment.
Recommendation:
• The pressure difference between zero (set point) and the measured pressure need not be known.
– POS. INPUT VALUE
• The pressure difference between zero (set point) and the measured pressure is known.
– CALIB. OFFSET
