Default value Dosing ramp
Dosing ramp
Dosing with uniform dosing rate (Dosing ramp = 0 s) or with slowly
increasing dosing rate.
Volume
Dosing a fixed volume per dosing step.
Dosing ramp
This parameter is visible only when Mode = Dosing ramp.
The dosing ramp is a delay in the dosing rate at the time of the start of a
dosing step. It is advantageous primarily for manual titrations with indica-
tor, when small volume steps are to be dosed before the equivalence
point. The selectable delay time determines after which amount of time (in
seconds) the defined dosing rate is to be reached.
