3.7 Installation procedure
A new amperometric dissolved oxygen sensor needs to be calibrated before it is installed into its
final measuring location. To install the device in the correct way, follow the order and the
following sections and their instructions.
1. Mount the sensor into the immersion assembly. (For further information refer to the manual of
the assembly)
2. Connect the sensor to the signal converter or directly to the control system.
3. Configure the measurement range. Calibrate the sensor.
4. Install the sensor into its final measuring location.
3.8 Sensor use without cleaning function
Before installation and immersion the sensor check the following order:
•
Do not install any flexible tubing.
•
Install a cap on the air line connector in order to avoid the cleaning drilling to be blocked for
later use or water to flow through it into a closed assembly.
INFORMATION!
Clean and grease all threads each time you open the housing. Use only resin-free and acid-free
grease. Before closing the cover, ensure that the housing gasket is properly fitted, clean and
undamaged.
WARNING!
Without a cap on the air line connector the sample might block the cleaning drilling for later use
or water might flow into a closed assembly and damage the probe due to later handling.
