• You must be logged in as a user with the right to perform calibrations. Fac-
tory-preset users have all of these rights.

• You must ensure that the calibration default settings for the individual analy-
sis inputs and, possibly, the universal inputs are set correctly. The explana-
tions of the calibration default settings can be found in the chapters on
calibration of the various analysis sensors.
• In the case of Ci analysis inputs, it should be noted that the optional boards
must undergo a basic calibration during the initial commissioning. If this has
not yet been performed, it is necessary to do so prior to any other calibration.

Manual entry of calibration values
If calibration values are known, they can also be entered manually. This may be
the case with temperature-compensated conductivity measurements, for in-
stance, when the temperature coefficient of a liquid is known. Known calibration
values are entered manually under:
Device Menu
r
Calibration
r
Select Analog Input
r
Calibration Values
NOTE!
Incorrectly entered calibration values result in incorrect measuring values.
Correct measurements are essential for control systems and limit
monitoring.
