Sequence/SAC
sequence Unlike Coupled methods, sequences also allow you to link reagent
calibration and electrode calibration methods.
A sequence is a chain of up to 3 methods that will be carried out in
different beakers and in a defined order given by the operator.
The beakers are changed automatically using a SAC80 or SAC850
Sample Changer.
Example:
Method 1 performed on 2 samples using 2 test portions
(2 x 2 beakers),
Method 2 performed on 1 sample with 3 test portions (1 x 3 beakers).
Thus 7 beaker system will run as follows:

The number of samples is entered in the Edit sequence menu and the
number of test portions in the Edit method screen.
