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.
Steady State
n
– 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.
3.16.5 'Parameter data' on page 181
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.
