Thermo Scientific
Note Before the instrument is switched off a clean air purge should be performed. This
ensures that the instrument is free from gas and ready for the next measurement. This final
purge is especially important for the oxygen sensor as it may degrade if stored when
contaminated with gas.
Note If the 'Auto Off ' utilities setting is set to 'Yes', the analyser will switch off
automatically after 10 minutes if not in use.
