Running A Sac Sequence - Radiometer Analytical TitraLab 870 Reference Manual

TitraLab ®
Running a SAC
sequence
1. Select SAC sequence,
2. If a Question mark "?" is present in the Reagent tab, it means that
the sequence needs to be programmed - a reagent is
missing. Review programming in Supervisor mode.
If necessary, edit the sequence,
page 181.
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 or
D21T085 for a SAC850/SAC950).
4. Connect/check the electrode(s).
Refer to "Electrode connection", page
5. Install/check the reagent(s).
6. Prepare the sample stack.
7. Press 1 in the Main window to run the sequence from the first
beaker of the sample stack.
To run a sequence from a given beaker number of the sequence,
press 2 in the Main window and 4 Start from...
8. If prompted to do so, enter the User's name (ID) and press 1.
9. 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 beaker. Titration starts.
- Between each sample tests (beakers), 1 to 9 dynamic rinses (if
programmed with a SAC850/SAC950) then 1 to 3 static rinses are
performed (if programmed to do so).
10. At the end, the Titration Manager displays the mean result and
standard deviation calculated for all accepted tests.
When running a sequence with a SAC80 Sample Changer,
do not use the STOP key of the SAC80.

Use the Left/Right arrow keys to select the
beaker you want to start the sequence then
press 1 Start from...
Limitations: you can only start a sequence:
- from the first beaker of an electrode or reagent
calibration,
- or when several replicates (tests) are edited
for a same sample, from the first beaker of that
sample.
