13. Adjust the outputs of other cells (not golden paths) to have between 7 to 8V by adjusting
the gains of their preamplifiers.
14. Set the jumper of the JP1 from position 2 (Test °C) to Position 3 (Analysis).
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.
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.
