This completes the calibration process. The new calibration value will be saved in the device.
9.4.2.4 Automatic calibration
The automatic calibration of the conductivity sensor is a one point calibration with automatic buffer detection.
The following conductivity calibrations are archived:
0.01 N KCl:
1.41 mS/cm (25 °C)
0.1 N KCl:
12.9 mS/cm (25 °C)
> You will be prompted to immerse the sensor into the calibration medium.
Confirm this dialog with (
ON/OFF
). The currently measured values will be displayed.
If the measured values (conduc temperature!) are in a stable condition,
reconfirm by pressing (
ON/OFF
).
This completes the calibration process. The new calibration value will be saved in the device.
If the calibration is faulty, an error message will be displayed (see
chapter 9.4.2.5).
9.4.2.5 Calibration error
The limits for all calibration values are saved in the meter. If the entered values are outside these limits, one of
the following error messages will be displayed:
„!
Incorrect entry!
“ or „
!Calibration error!
“.
You may have to repeat the calibration, service the sensor or replace it (wear part!).
