Calibration

The sensing part of the sensor must not be in direct contact with
water!
In the wet flow cell, the atmosphere will be saturated with water
vapor. This atmosphere will produce the most accurate calibration
results.
The required time for a calibration depends mainly on the difference
between temperature and oxygen content in the sample and in the
air. It can take 15–20 minutes. This is also the case if the electrolyte
was exchanged.
As soon as the reading is stable, the microprocessor will store the
calibration data in the memory.The end of the calibration is indicated
on the display.
To perform a calibration proceed as follows:
1 Navigate to menu <Maintenance> /<Calibration>.
2 Press [Enter] to start the calibration and follow the dialog on the
display.
