) A regular offset adjustment with connected potentiometer is recommended. The given offset specification
of the box module is therefore practically irrelevant. Therefore, specification values with and without offset
are given here. In practice, the offset component can be eliminated by the functions Tare and also
ZeroOffset [} 000] of the box module or in the controller by a higher-level tare function. The offset deviation
over time can change, therefore Beckhoff recommends a regular offset adjustment or careful observation of
the change.

Note: In Extended Range Mode the Underrange/Overrange display in the PDO status has the character of an information/warning
when the nominal measuring range is exceeded, i.e. no Error is displayed in the PDO status and LED. If the technical measuring range
is also exceeded, Error = TRUE is also displayed. The detection limit for Underrange/Overrange Error can be set in the CoE.
In Legacy Range mode, an Underrange/Overrange event also leads to an Error in the PDO status.
