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

Sample changer error: the sample changer connected does not corre-
spond to the one programmed in the Setup > Configuration menu.
Example:
A SAC80 is connected to the Titration Manager, SAC socket and you
have declared a SAC850 in the Setup > Configuration menu.
Review the Setup > Configuration parameters and/or connect the cor-
rect 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

is calculated after a one-point calibration.
