During pulse operation the switch 'Pulse adaptation or choke' enables an adaptation of
pulse energy, sometimes required for different cable assembly lengths.
During normal operation this switch 'Pulse adaptation or choke' is used to set the choke
influence.
The table below shows the function of the two Potentiometers, depending on the selected
Procedure.

The Switch without/with pulse is active if the procedure Normal-Synergic or Pulse-
Synergic was selected. You can change over from characteristic curve Normal synergic to
Pulse synergic.
