Appendix:
Minimum Spans for Current Outputs
The LDO 3400-170/4400-170 module is a measuring module. It does not pro-
vide current outputs. Current outputs are provided by the BASE module (basic
device) or by communication modules (e.g. OUT, PID). The corresponding
parameters must be set there.
The minimum current span shall prevent that the resolution limit of the
measurement technology (± 1 count) is seen in the current.
