The following error conditions can be selected.
Select: error in device (error category [F]) / application error (error category
[F]) / out of specification (error category [S])

Set measured value polarity, please note flow direction in C1.2.2!
Select: both polarities (plus and minus values are displayed) / positive
polarity (display for negative values = 0) / negative polarity (display for
positive values = 0) / absolute value (use for the output)

special function
Automatic range; select:
off (switched off)
automatic range (range is changed automatically, extended lower range,
only makes sense together with a status output)
external range (change by control input, extended lower range, control input
must also be activated)
C2.
.12
threshold
Appears only when Fct. C2.
.11 threshold is activated between extended
and normal range. The automatic range function always changes from the
extended to the normal range when the 100% current is reached.
The upper 100% value of the hysteresis is then = 0. The threshold is then the
hysteresis value, instead of "threshold
±
hysteresis" as shown in the display.
