Once you have selected the sensor type, the prompt automatically
appears asking whether the sensor parameters (zero point) have
to be determined. You can initiate this prompt manually as follows:
Continuous display ➨ Menu ➨ or
[Measurement] ➨ ➨
or
[Measuring channel X Conductivity] ➨ or
[Sensor parameter adjustment] ➨ .
1.
Use the arrow keys to select
[Automatically determine sensor parameters].
2.
Continue with .
ð
You will see the display showing
[Sensor dry] and
[Automatically determine sensor parameters].
3.
Continue with .
ð
You will see the display with the message
[Sensor parameters are automatically determined].
The sensor parameters are automatically carried over.
