10.4 Calibration of auxiliary variables
Auxiliary variables can be adjusted in the M5/S2 section. You can reach this section by
tapping on the Calibration button and swiping left.
The closed lock shows, that the analyzer is still in operating mode, while this screen is
open.

Set point values
By tapping on the set point values, the temperature, pressure or flow rate can be adjusted.
The actual values change to the new set points.
Please note, that in some configurations the temperature is fixed and
Note
cannot be changed.
The pressure sensors P-IN and P-OUT can be calibrated when there is no gas present in the
analyzer. The calibration point is set at the atmospheric pressure of the ambient air.
The pressure sensors should be calibrated occasionally. To calibrate the pressure sensors,
please remove all gas lines from the analyzer. The removing of the gas lines makes sure
that there is no gas flow during the sensor calibration. The pressure sensors will adapt to
the atmospheric pressure. Please use a pressure measuring device to determine the cur-
rent barometric pressure. Enter this value in the 'Set point' field. The pressure sensors are
now calibrated and the gas lines need to be connected to the analyzer again.
If you change the P-IN set point and don't disconnect the gas
connections, both P-IN and P-OUT will accept the same value. In this
Note
case the gas flow rate is set to zero and the flow measurement after
this change will not reflect the true flow value.
