Function Switch
This switch is used to select the gas mixture range to agree with the
composition of the sample. Gas compositions for which your analyzer is
intended are hydrogen and carbon dioxide (0-100% H
2
in CO
2
), or air and
carbon dioxide (0-100% air in CO
2
), or purity of hydrogen (e.g. 90-100%
H
2
with 0-10% impurities).

Cell Temperature
Generally the cell temperature is stable within 30 minutes of switch-
ing on the analyzer. The indicator lamp on the front panel shows when the
heater is on, and when it is flashing the cell is up to its operating tempera-
ture.
