S sensor only has a limited service life depending on the operating mode and is
therefore excluded from the analyzer guarantee.
Proceed as follows to remove the old sensor:
1. Flush the gas path for about 10 minutes with zero gas (AUTOCAL)
2. When sample gas is no longer present in the gas path, disconnect the analyzer from the
supply voltage.
3. Open the unit by removing the four bolts on the cover.
