« Span gas value » field: span gas cylinder concentration used to perform calibration check. This
concentration is the reference value to be reached.
« Calib. ON/OFF » field: this field is used when the analyzer can measure many gases. It allows to
perform a gas-by-gas calibration with no effect on the other gases. It invalidates or not the auto-
calibration for the considered gas.
« Response time » field: shows response time value. Refer to Chapter 2 of this manual for more details.
« Filter autonomy (d) » field: shows the new zero air filter autonomy (day number). The analyzer
decrements each day from this value (refer to synoptic display of the standard function screens). A
control triggers when it lasts 120-day autonomy, and an alarm is triggers when it lasts one-day
autonomy.
« Kicker autonomy » field (d): shows the new carbon kicker filter autonomy (day number). The analyzer
decrements each day from this value (refer to synoptic display of the standard function screens). A
control is triggers when it lasts 120-day autonomy, and an alarm is triggers when it lasts one-day
autonomy.
« Init. Counter OFF/ON » field: reset filter autonomy to the programmed value after a filter change.
« Dilution OFF/ON » field: used to activate the dilution function and to set the dilution coefficient.
3.4.2.12. Automatic linearization of the flow
This screen is accessed by touching/clicking-on . It allows to linearize the flow value as function of
the corresponding pump set point.
Before linearization launching, the user must connect a flowmeter (0-100 nl/h) to the suitable fluid inlet.
Then, he clicks-on/touches the corresponding fluid inlet button , or , or , and he inputs in
the « Nominal » field the read value on the flowmeter. Then, he launches linearization by
touching/clicking on . Then, the analyzer will be in a maintenance mode for around 5 minutes.
REMARK: the in-factory pump setting is 100% by-default.
