n
Input Freeze
–
In the activated state no measurement values are passed to the digital filter.
–
As long as the command bit is set, this bit remains set.
n
Steady State
–
As soon as a measured value is longer than the time
SSW
within the tolerance
window
SST
, in the status word the
Steady State
bit is set.
–
As soon as this condition is not true, the last measured value is first used, the
comparison timer restarted and the bit is reset.
–
The values
SSW
and
SST
can be specified by the parametrization.

n
Self calibration
–
As long as the self calibration is active, this bit is set.
–
During the self calibration there are two reference values internally measured and
based on this the internal offset & factor are calculated.
–
With the self calibration the internal offset and gain error may be compensated.
–
The calibration interval
CI
can be preset by the parametrization.
