Select the requested mode and save with [OK]. By pushing [->], you
reach the next menu item.

The current output is used to transfer the measured value to a higher
ranking system, for example to a PLC, a control system or a meas-
ured value indication. This is an active output, i.e. a current is provided
actively. The processing unit must hence have a passive current input.
