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.
To consult the calibration results,
