Individual parameters for EP1.
Preset EP1 at pH, U, or I, resp.
Distance from EP where constant dosing
stops and controlling begins.
Maximum dosing rate.
Minimum dosing rate.
Type of stop criteria.
Titration stops if stop drift is reached.
Stop if there is no dosing during t(delay).
If t(delay) is ”INF”:
stop after a time.
