Procedure
1.
If you have not made any initial settings for local calibration, please make them in the "
Ñ
>
Set up 1 > Calibration" menu.
2.
Set the service switch to "Service" (vertical) or move the assembly into the Service position
3.
Remove the sensor.
4.
Clean the sensor before calibration.
!
Note!
• When measuring with PM (potential matching), the PM line also has to be immersed in the buffer
solution.
• If automatic temperature compensation is selected for calibration (ATC), the corresponding
temperature sensor must also be immersed in the buffer solution.
• The instrument switches automatically to Hold (factory setting) whenever it is calibrated.
• Press
Ò
to cancel the calibration. In the dialog field that follows, select "Yes, abort cal.".
The following section describes the calibration cycles for:
Calibration pH
• ""Manual data input"
• "Cal with manual buffer"
• "Cal with buffer table"
• "Cal with automatic buffer recognition"
Calibration, redox absolute
• "Data input absolute"
• "Calibration, absolute"
Calibration, redox relative
• "Data input absolute"
• "Data input relative"
• "Calibration, absolute"
• Calibration, relative

Ending calibration
Accept:
When you confirm with

, the new
calibration data are accepted.
Cancel:
The data are not accepted. Calibration
is not repeated.
Repeat calibration:
The data are rejected and
calibration is repeated.
