Operation

5.1

Start-up

Each sensor is supplied ready to use. Before using re-
move the protecting cap.
Attention! No polarization or calibration is necessary.
"plug and measure"

5.1.1 ISM data handling

After connecting the sensor to the transmitter, the user
is asked to enter the following information.
The transmitter asks you to enter some information:
– Shaft serial number: XXX
Enter the serial number of the sensor shaft,
labeled on the thread sleeve.
– Membrane Exch:
Enter Yes, if you have changed the opto-cap
– Shaft Autoclave:
Enter Yes, if the shaft has been autoclaved
These data are stored in the sensor head and are
available on call for a proper sensor documentation.

Calibration

5.2.1 Purpose of calibration

Information about the calibration, you find also in the
manual of the transmitter.
Calibration should be performed after each change of
the opto-cap, sterilizing or after autoclaving the sensor.
Three different calibration methods are available:
– Single point calibration
– Dual point calibration
– Process calibration
Each oxygen sensor has its own individual phase
angle at zero oxygen (phi 0) and hundred percent oxy-
gen (phi 100). Both values are subject to change, for
example, after exchange of opto-cap. To ensure high
measurement accuracy of the sensor, a calibration
must be carried out after each change of opto-cap.
A zero point calibration is only advisable if very high
accuracy is required at low oxygen concentrations.
To check if your sensor needs a recalibration, you
may dry it and take it in the air to check that the read-
ing is close to 100%. If not, the sensor needs a new
calibration.

5.2.2 Factory calibration

The sensor is delivered pre calibrated and ready for
use. To activate this calibration refer to the transmitter
manual.
