• Go to «Tools» > «Terminal» and send setup command s:02 according
to application needs. (possibility of adjustment see below)

For details (commands etc.), see next tables.
Remark: Each pressure control algorithm has its own parameters. That
means the adjustment of a e.g. adaptive downstream parameter (e.g.
Ramp Time "Adaptive downstream") doesn't influence one of the other
Ramp time parameter of other pressure control algorithms and vice
versa.
