15. Install the IR module into the analyzer.
16. . Allow sufficient time for the base lines to stabilize.
NOTICE
It is necessary to turn slowly in order for the IR sources to stabilize their
temperature with increasing IR source voltage.
• Adjust the other cells of the module (if any) at 8V baselines or 5V to 6V in
case of clean golden paths.
• Install the IR module into the analyzer. Allow sufficient time for the base lines
to stabilize.
• Start gas flow and check the base lines again. If any of them is significantly
over 8V then readjust.
4.2.6.2 Drift too large
• Check the temperature regulation.
• Unstable power supply.
• Defective IR-source.
NOTICE
If it is shown on the display that the infrared cell's output voltage is over 10 volts
then there is a serious defect.
