Reagent
calibration (SAC
sequence)
In a calibration sequence, the standard solution beakers are handled
automatically using a sample changer. A SAC80, SAC90, SAC850 or
SAC950 Sample Changer must be connected and declared in the
Configuration menu.
1.
Select the SAC Sequence option in the Main window. This SAC
Sequence must use the reagent to be calibrated.
2.
If a Question mark "?" is present in the Reagent and/or Electrode
tabs, it means that the sequence needs to be programmed - a
reagent or an electrode is missing. Review programming in
Supervisor mode.
Refer to "Programming sequence", page 159
.
3.
Install the sample changer and connect it to the SAC socket of the
Titration Manager using the cable, part no. A95A202 or A95X501.
Refer to the User’s Guide of the sample changer
(part no.: D21T002 for a SAC90, D21T013 for a SAC80, D21T085
for a SAC850 or SAC950).
4.
Install the reagent,
see "Install reagent", page 126
5.
Connect the electrode system,
see "Electrode connection", page
.
6.
Press 1 Calibrate/Enter titre in the Reagent window.
7.
Select the reagent from the list of the reagent system.
8.
Press 3 Calibration sequence.
9.
Prepare the reagent calibration stack,
.
10. Press Esc then 1 to run the calibration sequence. Follow the
messages on the display.
11. The sample changer cycle is initiated.
- 1 to 9 dynamic rinses (if programmed with a SAC850/SAC950)
- 1 to 3 static rinses (if programmed).
- Electrodes are dipped into the first standard solution.
Measurement starts.
- Between each calibration beakers, 1 to 9 dynamic rinses (if pro-
grammed with a SAC850/SAC950) then 1 to 3 static rinses are
performed (if programmed to do so).
12. At the end, the Titration Manager displays the calibration results.
The calibration results are saved with the reagent.
To consult the calibration results,
When running a calibration sequence with a SAC80 Sample
Changer, do not use the STOP key of the SAC80.
