• The values for "Empty calib./Full calib.", "Empty height/Full height" 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 and the measuring task for the measuring 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 ä 37, "Position zero adjustment".
