Then adjust the value of Head temperature : it must be equal to :

The Atmos. temperature , if the Relative humidity is lower than 60%,

The Atmos. temperature , + 5°C, if the RH relative humidity is higher than 60%.
NOTE : Refer to the section 3.3.7.2 for procedure details.
5/ Carry out a flow rate calibration ( « CALIBRATION

Flow rate » menu) :
Using a reference flow meter placed instead of the sampling head, calibrate the flow rate.
NOTE : If the analyzer is equipped with the RST option, check, in the « CONFIGURATION

Measurement mode » menu, that the RST option is correctly activated, before carrying
out the calibration. Refer to section 3.3.3.3 for calibration procedure details.
6/ Configure the measurement mode and the measurement channels in the « CONFIGURATION »
menu.

Measurement mode advised : 2h periods and 24h cycles, 200 s counting duration.

Measurement channels advised :
