28.4 Manual titrations (MAT)
NOTE
Start of titration: Because of the technical implementation involved, a
few microliters are already dosed at the start of a manual titration. The
possibility of deviation from the actual endpoint volume is excluded,
however, because the already dosed volume is taken into account.
End of titration: A manual titration must always be ended with the
button [Cancel command] (NOT with the fixed key [
]). This is the
only way to ensure that subsequent method commands will be carried
out.
28.4.1 Dosing parameters
Under [Dosing parameters], the parameters influencing the sequence of
the manual titration are defined.
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
the defined dosing rate is to be reached.
Input range 0 - 10 s
Default value 2 s
Dosing rate
Rate at which it is dosed.
Input range 0.01 - 166.00 mL/min
Selection maximum
Default value maximum
maximum
The maximum dosing rate depends on the cylinder volume (see Chap-
ter 31, page 406).
Time interval MP
Time interval for entering a measuring point in the measuring point list.
The measuring point list is limited to 1000 measuring points.
Input range 0.1 - 999999.0 s
Default value 5.0 s
