• The values entered for "Empty Calib./Full Calib.", "Empty Pressure/Empty Pressure" and
"Set LRV/Set URV" must be at least 1% apart. The value will be rejected, and a warning
message displayed, if the values are too close together. Further limit values are not checked,
i.e. the values entered must be appropriate for the sensor module and the measuring task for
the device to be able to measure correctly.
• Due to the orientation of the device, there may be pressure shifts in the measured value, i.e.
when the container is empty or partly filled, the measured value is not zero. For information
on how to perform position adjustment, see (
