Manual dosing A manual dosing consists in adding varying size of reagent volumes
at varying addition speeds with or without measuring a signal. No
measurements are stored.
1. Select the method, see "Select method", page 203 .
2. Install the burette, see "Install burette", page 125 .
3. Install the reagent on the burette, see "Install reagent", page 126 .
4. Connect the electrodes if measurements are to be performed,
see "Electrode connection", page 102 .
5. If you want to measure pH, run an electrode calibration when a
Stormy icon appears in the Electrode tab.
6. Press 5 Manual dosing in the Reagent window.
7. Press 1 Run.
Refer to "Running a manual dosing", page 192 .
