Calibration

The following information can also be seen:

points Fig. 55, Pos. 6 and 7
Curve description Display of calibration curve description
(Fig. 55, Pos. 4)
Adjustment mode The adjustment mode adjusts the calibration to
the changed environmental conditions (e.g.
change of the mould or the source).
Two different modes are available for calculat-
ing the new calibration curve (Fig. 55, Pos. 5):
Note
BERTHOLD TECHNOLOGIES recommends that the calibration mode
be set to "dynamic" (Fig. 55, Pos. 5) if only an empty calibration is
carried out before casting.
If both an empty and a full calibration are performed, the recom-
mended mode is "fixed".
Dynamic Fixed
In the dynamic adjustment mode, the
100% value is mathematically inter-
polated using the newly read 0%
value during an empty adjustment
and the whole calibration is adjusted
accordingly. In the fixed adjustment mode, the 0%
value is read anew during an empty ad-
justment. However, the 100% value re-
mains unaltered. The points in between
are adjusted accordingly.
Background Level The background level indicates the natural back-
ground radiation if no radiation source is in-
stalled.
Measurement Range Assignment of the 0% and 100% values for the
fill level measurement, if the unit for measuring
the fill level is a unit length (mm or inch). The
setting can be performed under
<System menu
| Settings | Units>.
