Reagent
calibration 1. Select the method which uses the reagent to be calibrated.
2. If a Question mark "?" is present in the Reagent and/or Electrode
tabs, it means that the method needs to be programmed - a rea-
gent or an electrode is missing. Review programming in Supervi-
sor mode.
Refer to "Programming method", page 138 .
3. Install the reagent(s), see "Install reagent", page 108 .
4. Connect the electrode, see "Electrode connection", page 86 .
5. Press 1 Calibrate/Enter titre in the Reagent window.
6. Select the titrant from the list.
7. Press 1 Run calibration and follow the messages on the display.
8. Measurements start.
The titre ±standard deviation is calculated at the end of the
calibration cycle. The calibration results are saved with the
reagent.
