7.8.1 Service Parameters
In this display, parameters relating to the carrier gas can be viewed and adjusted.
Calibration value for carrier gas stream:
This value indicates the current set point for the carrier gas flow acquired during the last calibration. If
the actual value does not match the calibration value and allowable deviation, the measurement is ab-
orted and the error must be corrected before a new measurement can be started.
Permitted deviation:
This value indicates the allowable deviation of the actual carrier gas flow to the calibration value of the
carrier gas flow.
Also measure for gas flow errors (user level 3 only):
This feature allows the analyser to take a measurement even if the allowable deviation of the actual car-
rier gas flow from the calibration value of the carrier gas flow is exceeded.
Calibration of the carrier gas (user level 3 only):
With this function, deviations of the sensor signals between carrier gas ON and OFF (for example due
to aging) can be compensated. Make sure the system is tight before compensating the sensor signals.
Carrier gas ON:
This value indicates the flow of carrier gas input.

Notice
The carrier gas flow calibration value defines the carrier gas inlet and outlet
set point in the status screen (Chapter 7.5 on page 97).
