Working mode Select the way in which you want to work.
Method : to run a single method.
Sequence : to create or run a sequence of methods. Beakers are
manually changed between two method runs.
SAC Method : to run a single method to be performed using a sample
changer.
SAC Sequence : to create a sequence of methods to be performed
using a sample changer.
Reprocessing : to reprocess in manual mode the last titration curve
obtained.
Note: the working mode selected will have no effect on the type of
method you wish to create.
Define the sample changer in the Configuration menu before
selecting SAC Method or SAC Sequence.

Wrong buffer While running an electrode calibration, the buffer analysed has not
been identifed by the instrument.
End the calibration cycle. Check the buffer then start a new calibration
cycle.
Wrong type
(SAC error) Sample changer error: the sample changer connected does not corre-
spond to the one programmed in the Setup > Configuration menu.
Example:
A SAC850 is connected to the Titration Manager, SAC socket and you
have declared a SAC950 in the Setup > Configuration menu.
Review the Setup > Configuration parameters and/or connect the
correct model of Sample Changer to the SAC socket of the Titration
Manager.
Refer to the Sample Changer User’s Guide, part no. D21T085.
Zero pH This is the pH value (pH
0
) at which the potential is zero. The zero pH
is calculated after a one-point calibration.
Refer to "pH0(25)", page 169 .
