The values entered for "Empty Calib./Full Calib.", "Set LRV/Set URV", and the applied
pressures 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.
