- 0.1 % when it is used as control output
- 0.05 % when it is used as analog retransmission. Note
Note Note Note Note: a too
little range scaling can deteriorate the output accuracy.
Filter Filter Filter Filter Filter: It is possible to apply a first order digital filter on the
retransmitted value.
The time constant of the filter may be programmed within 0 and
8 s.
