Operating temperature
If the analyzer has been stored at low temperatures, it will require some
time to equilibrate to the ambient temperature before being switched
on. If it does not equilibrate, condensation will occur inside the analyzer!
If the temperature is out of its operation range you will see the follow-
ing messages on the display:
“Analyzer too hot”
or
“Analyzer too cold”
Once one of these messages appears you will not be able to use the an-
alyzer, it will give an acoustic signal until it has reached the specified
operation temperature b5°C and +45°C
