time will be 2 seconds. If, after this time, the measurement value deviates by more than 10%, the
sample time will remain 2 seconds between sensor readings. If the measurement value deviates
less than 5%, the sample time will be doubled up to a maximum of 60 seconds between sensor
readings.
Therefore:
1. If the deviation is > 10% between consecutive readings:
 The sample time is changed to 60  30  15  8  4  2 seconds, respectively.
OR
2. If the deviation is < 5% between consecutive readings:
 The sample time is changed to 2  4  8  15  30  60 seconds, respectively.

SAMPLE APPLICATION

4.5.8
4.5.8.1 Gas Application
When the gas application is selected, the sensor will always measure partial oxygen pressure.
That means the sensor will measure oxygen values in relation to the calibration air. O
atmospheric pressure do not need to be compensated. When O
then the O value has to be compensated with the measured pressure.

For example:
Patm during calibration: 1013 mBar
O measured 1.033 Bar (20 cm H

O Patm= 0.981 %

4.5.8.2 Liquid Application
When the sensor will be used in liquid, the O
The settings can be set/changed as follows:
1. Select 'Sensor settings' in the Configuration menu and press the Enter button. The
Sensor settings menu will be displayed.
2. In this menu, use the cursor keys to select the desired item and press the Enter button to
confirm the selection.
3. The cursor keys can then be used to select the desired settings.
4. Press the Enter button to return to the Sensor settings menu.
5. Use the cursor keys to select the Return sign and press the Enter button to return to the
Configuration menu.

ANALOG OUTPUTS

4.5.9
The 9065 offers two analog outputs that can be configured as desired. After selecting and
confirming 'Config. Output', the corresponding settings for the unit will be displayed
automatically. The settings depend on the unit that has been selected in 'Units'. The range will be
altered accordingly if the unit is changed. An overview of the settings and the default settings is
given below.
