OPERATION

3.2 Start-Up

After 

fi

 nishing and verifying the connections, power up the analyzer.

Oven Temperature

Low alarm /xxx.x

During warm-up, the display shows:

The measured temperature value alternates with the message "Low alarm" during one 

second in every two seconds.

When the  temperature is within 30°C of the required temperature (after about 15 

minutes), the system calculates the oxygen concentration and the result will appear on 

the display.

O2 Concentration

xx.xx %

Then the following default message appears:
