Lus Cim:

1. Lub cuab yeej tsuas yog tsim thiab ua cov ntaub ntawv sampling raws li MinTime Interval. Thaum nws tsaug zog, nws tsis sau cov ntaub ntawv.
2. Cov ntaub ntawv khaws tseg yog muab piv nrog cov ntaub ntawv kawg qhia. Yog tias cov ntaub ntawv sib txawv ntau dua li Tus Nqis Tshaj Qhia Hloov pauv, cov cuab yeej tshaj tawm raws li MinTime luv. Yog tias cov ntaub ntawv hloov pauv tsis ntau dua li cov ntaub ntawv kawg tau tshaj tawm, cov cuab yeej tshaj tawm raws li MaxTime luv.
3. Peb tsis pom zoo kom teeb MinTime Interval tus nqi qis dhau. Yog tias MinTime Interval tsawg dhau lawm, lub cuab yeej sawv ntau zaus thiab lub roj teeb yuav poob sai sai.
4. Thaum twg lub cuab yeej xa ib daim ntawv tshaj tawm, tsis muaj teeb meem tshwm sim los ntawm cov ntaub ntawv hloov pauv, khawm thawb lossis MaxTime lub sijhawm, lwm lub voj voog ntawm MinTime / MaxTime xam pib.

Kev teeb tsa

1. R720E yog pasted nrog 3M ob-sided daim kab xev (Daim duab 1 hauv qab). Ua ntej, tshem tawm qhov nruab nrab ntawm daim kab xev ob sab (daim duab liab hauv daim duab 1).
2. Tshem tawm daim ntawv thaub qab ntawm ib sab ntawm daim kab xev ob sab, thiab muab daim kab xev ob sab rau sab nraum qab ntawm lub cuab yeej (Daim duab 2 hauv qab).
3. Thaum kawg, rhuav tshem daim ntawv thaub qab ntawm sab nraud ntawm daim kab xev ob sab, thiab muab cov cuab yeej tso rau ntawm phab ntsa lossis lwm yam khoom. (Thov tsis txhob lo lub cuab yeej rau ntawm phab ntsa ntxhib lossis khoom kom tsis txhob siv lub cuab yeej ntog tom qab siv sijhawm ntev.)

Nco tseg:

• Ua ntej kev teeb tsa, nco ntsoov so cov phab ntsa lossis lwm yam khoom kom huv si kom tsis txhob muaj plua plav ntawm phab ntsa lossis lwm yam khoom uas yuav cuam tshuam rau kev teeb tsa.
• Tsis txhob nruab lub cuab yeej hauv lub thawv hlau thaiv lossis ib puag ncig nrog lwm cov khoom siv hluav taws xob nyob ib puag ncig kom tsis txhob cuam tshuam cov teeb liab xaim hluav taws xob ntawm lub cuab yeej.
• Thaum muab 3M ob-sided daim kab xev, nco ntsoov lo daim kab xev ob sab hauv cov qauv ntawm cov cuab yeej kom tsis txhob cuam tshuam cov tsos.

1. R720E kuaj pom raws li Min Sijhawm. Thaum kuaj pom TVOC tus nqi lossis roj teeb voltage yog muab piv nrog rau daim ntawv tshaj tawm kawg, tus nqi tshaj li tus nqi teev. (Default TVOC Tus Nqi: 300ppb; Default Battery Voltage: 0.1V) Yog tias TVOC concentration tshaj 300ppb lossis roj teeb voltage tshaj 0.1V, tam sim no kuaj TVOC, kub, thiab av noo yuav raug xa mus.
2. Yog qhov txawv ntawm TVOC concentration lossis roj teeb voltage tsis pub tshaj tus nqi teev, cov ntaub ntawv qhia tsis tu ncua raws li Max Lub Sijhawm.

Nco tseg: Lub Sijhawm Min thiab Max Sijhawm default 15 feeb.

Cov ntaub ntawv hais txog roj teeb Passivation

Ntau yam ntawm Netvox li yog siv los ntawm 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) roj teeb uas muaj ntau yam advantages suav nrog tus nqi qis tus kheej tawm thiab siab zog ceev. Txawm li cas los xij, thawj cov roj teeb lithium zoo li Li-SOCl2 roj teeb yuav tsim cov txheej txheem passivation raws li cov tshuaj tiv thaiv ntawm lithium anode thiab thionyl chloride yog tias lawv khaws cia rau lub sijhawm ntev lossis yog tias qhov ntsuas kub siab dhau lawm. Cov txheej txheej lithium chloride no tiv thaiv tus kheej tawm sai sai los ntawm cov tshuaj tiv thaiv txuas ntxiv ntawm lithium thiab thionyl chloride, tab sis roj teeb passivation kuj tuaj yeem ua rau vol.tage ncua sij hawm thaum cov roj teeb tau muab tso rau hauv kev ua haujlwm, thiab peb cov khoom siv yuav tsis ua haujlwm raug rau qhov xwm txheej no. Yog li ntawd, thov nco ntsoov cov roj teeb los ntawm cov neeg muag khoom txhim khu kev qha, thiab cov roj teeb yuav tsum tau tsim nyob rau hauv peb lub hlis dhau los. Yog tias ntsib qhov teeb meem ntawm roj teeb passivation, cov neeg siv tuaj yeem qhib lub roj teeb kom tshem tawm cov roj teeb hysteresis.

• Txhawm rau txiav txim siab seb lub roj teeb puas yuav tsum tau ua kom txuas lub roj teeb ER14505 tshiab rau 68ohm resistor nyob rau hauv parallel, thiab xyuas cov vol.tage ntawm lub voj voog. Yog voltage yog qis dua 3.3V, nws txhais tau tias lub roj teeb yuav tsum tau ua kom.
• Yuav ua li cas qhib lub roj teeb

1. Txuas lub roj teeb rau 68ohm resistor nyob rau hauv parallel
2. Khaws qhov kev sib txuas rau 6 ~ 8 feeb
3. Qhov voltage ntawm Circuit Court yuav tsum yog ≧3.3V

Cov Lus Qhia Tseem Ceeb Saib Xyuas

Cov cuab yeej yog cov khoom lag luam nrog kev tsim qauv zoo thiab kev ua haujlwm zoo thiab yuav tsum tau siv nrog kev saib xyuas. Cov lus qhia hauv qab no yuav pab koj siv cov kev pabcuam lav paub zoo.

• Khaws cov cuab yeej qhuav. Los nag, ya raws, thiab ntau yam kua lossis dej tuaj yeem muaj cov zaub mov uas tuaj yeem ua rau cov hluav taws xob tawg. Yog tias lub cuab yeej ntub, thov kom nws qhuav.
• Tsis txhob siv lossis khaws cia rau hauv qhov chaw muaj plua plav lossis qias neeg. Txoj kev no tuaj yeem ua rau nws cov khoom sib cais thiab cov khoom siv hluav taws xob puas.
• Tsis txhob khaws cia rau hauv qhov chaw kub heev. Qhov kub thiab txias tuaj yeem ua rau lub neej luv luv ntawm cov khoom siv hluav taws xob, rhuav tshem cov roj teeb, thiab deform lossis yaj qee qhov yas.
• Tsis txhob khaws cia rau hauv qhov chaw txias heev. Txwv tsis pub, thaum qhov kub nce mus rau qhov kub thiab txias, noo noo yuav tsim sab hauv uas yuav ua kom puas lub rooj tsavxwm.
• Tsis txhob muab pov, khob, lossis co lub cuab yeej. Kev kho cov khoom siv ntxhib tuaj yeem rhuav tshem cov vaj huam sib luag sab hauv thiab cov qauv muag.
• Tsis txhob ntxuav nrog cov tshuaj muaj zog, cov tshuaj detergents, lossis cov tshuaj detergents.
• Tsis txhob pleev xim rau lub cuab yeej. Smudges tuaj yeem ua rau cov khib nyiab thaiv qhov chaw uas tshem tau thiab cuam tshuam rau kev ua haujlwm ib txwm muaj.
• Tsis txhob muab lub roj teeb pov tseg rau hauv qhov hluav taws kub kom tsis txhob muaj lub roj teeb tawg. Cov roj teeb puas tseem tuaj yeem tawg.
• Tag nrho cov lus qhia saum toj no siv sib npaug rau koj lub cuab yeej, roj teeb, thiab cov khoom siv ntxiv.
• Yog tias ib yam khoom siv tsis ua haujlwm zoo.
• Thov coj mus rau qhov chaw muab kev tso cai nyob ze tshaj plaws los kho.
