Calibration with manual buffer, calibration with buffer table, calibration with automatic
buffer recognition
• Manual buffer:
The buffer pH value is entered manually. The display then shows the current measured value.
• Buffer table:
In the calibration menu, specify two buffer solutions or define yourself. The selected pH value and
buffer type are displayed.
• Automatic buffer recognition:
The device automatically recognizes the used buffer. Preselect the buffer types (e.g. E+H) in the
calibration menu.
Press
Ï
to start calibration.
Sensor communication Waiting for sensor response ... (only available for digital sensors with
Memosens technology.)
The transmitter transmits calibration data to the
sensor.
Note • Data saved
• Data NOT saved (only available for digital sensors with
Memosens technology.)
Indicates whether the calibration data could be
saved in the sensor. Calibrate the sensor again if
the process of saving the data failed.
Note Electrode in medium? Ensure that the electrode is in the medium
again so measuring can take place.

• mV 1: 0
•
°
C: 25.0
Wait until the pH measurement is stable:
Time no longer counts.
pH value no longer flashes.
mV value no longer flashes.
Once these values are stable, confirm with
F
.
!
Note!
Specify the criteria for the stability check in the
"Set up 1 > Calibration > Cal settings" menu.
The three previous steps are carried out for buffer 2.
Calibration value notice Invalid calibration value This message is displayed if an error is present
(e.g. wrong buffer used).
Zero point, slope notice • Zeropoint: 7.00
Good
• Slope: 59.00
Good
Information on the zero point, slope and quality
of the calibration is displayed here.
