5.3 Current outputs
The function group CURRENT OUTPUT is
used to configure the individual outputs.
Either a linear (O2 (1)) or, in conjunction with
the S version, a user-defined current output
characteristic (O2 (3)) can be entered. Furthermore, a current output value can be
simulated to check the current outputs (O2 (2)).
