1) Gawo la sensa ya gasi limagwirizanitsa masensa ndi ma circuit processing, paokha ndi kukwaniritsa ntchito zonse za deta ndi kutembenuka kwa chizindikiro cha chowunikira mpweya. Kutentha kwapadera kwapadera kumakulitsa mphamvu yochepetsera kutentha kwa detector; Gawo la detector leak gas limayang'anira magetsi, kulumikizana, ndi ntchito zotulutsa;
2) Ili ndi ntchito yodzitchinjiriza yodzimitsa yokha ya gawo la sensa ya gasi pomwe mpweya wambiri umapitilira malire. Zimayamba kudziwika panthawi ya masekondi a 30 mpaka kukhazikika kumakhala kozolowereka ndipo mphamvu imabwezeretsedwa kuti iteteze mpweya wambiri kuti usasefukire ndikuchepetsa moyo wautumiki wa sensa;
3) Malo olumikizirana a digito amagwiritsidwa ntchito pakati pa ma module, ndipo zikhomo zokutidwa ndi golide zomwe zimalepheretsa kuyika mwangozi ndizosavuta kusinthana ndikusinthana pamalopo;
4) Kusintha kosinthika ndi kuphatikiza kwa ma module angapo ojambulira gasi ndi mitundu yosiyanasiyana ya ma sensor sensors amatha kupanga zowunikira zosiyanasiyana ndi ntchito zinazake zotuluka ndi zinthu zozindikirika, kukumana mwachangu ndi zosowa za ogwiritsa ntchito;
5) Kuphatikiza kosinthika komanso mitundu ingapo yotulutsa
Ma module angapo ojambulira ndi mitundu ingapo ya ma module a sensa amatha kuphatikizidwa mosavuta kuti apange zowunikira zomwe zimakhala ndi ntchito zapadera zomwe zimagwiritsidwa ntchito pazolinga zosiyanasiyana kuti zikwaniritse zofuna za makasitomala;
6) Bwezerani sensa mosavuta ngati m'malo mwa babu
Sensor modules ya mpweya wosiyanasiyana ndi ma ranges akhoza kusinthidwa momasuka. Palibe calibration chofunika pambuyo m'malo. Ndiye kuti, chojambuliracho chimatha kuwerenga zomwe zidasinthidwa kale kufakitale ndikugwira ntchito nthawi yomweyo. Mwanjira imeneyi, mankhwalawa amakhala ndi moyo wautali wautumiki. Pakadali pano, kuwongolera kuzindikira kumatha kuchitika mosavuta pamasamba osiyanasiyana, kupewa zovuta zomatula komanso kusanja kwapamalo ndikuchepetsa mtengo wokonzanso pambuyo pake.
