14.2.2 Calibration default settings for Redox sensors
Before you can perform a calibration, you must first enter the necessary calibra-
tion default settings. The possible settings for the Redox calibration are de-
scribed in the following.
Open the calibration default settings:
Device Menu > Calibration > Select Analysis Input for pH/redox/NH
3
> Calibra-
tion Presets
Redox calibration default settings
The calibration default settings enable the calibration routines to be accessed in
the particular calibration menu.
Calibration routines that are not enabled are not visible in the calibration menu.
Additional calibration default settings are explained in the following table.
NOTE!
The "Calibration default settings" menu appears in the Device menu only if a
user with corresponding user rights is logged in.

Parameters Possible settings Explanation
Redox test solution -1500 to +1500 mV Manual entry of the Redox potential of
the test solution being used for calibra-
tion
NOTE!
Remember that the configuration of the redox measuring input must be set to
the redox unit "mV" for the zero-point calibration and to "Percent" for the two-
point calibration.
