Auto calibration
• Select the list item Auto calibration.
• Press ENTER.
The calibration is carried out.
Auto activation
• Select the list item Auto activation.
•Select On if the offset of the sound speed obtained during the field calibration is to be used for the calculation of the
physical quantity for analysis.
• Press ENTER.
For the verification of the offset, the auto activation can be switched off in case a service is required. In extreme cases, an
error of the physical quantity for analysis is displayed.
•Select Off in case the offset of the sound speed is not to be used. The transmitter works with the measured sound
speed without any correction.
• Press ENTER.
Deletion of samples
• Select the list item Clear samples.
•Select Yes to delete the samples.
• Press ENTER.
10.6 Display of measured values
The measured values are displayed during the measurement as follows:
By pressing or , additional physical quantities can be displayed during the measurement.
• Press to display the measured values in line 5. The designation of the physical quantity is displayed in line 4 by
pressing for several seconds.
• Press to display the measured values in line 4. The designation of the physical quantity is displayed in line 5 by
pressing for several seconds.
If several reference values were stored, e.g., when realizing diverse samplings with different concentrations, an
average is made during the auto calibration which is valid for the entire operating range.
