Daim duab 41 Sensor Information
USB chaw nres nkoj muaj kev sib txuas lus muaj nuj nqi, siv USB hloov mus rau Micro USB xaim txuas lub ntes mus rau lub computer. Nruab tus tsav tsheb USB (hauv pob installer), Windows 10 system tsis tas yuav nruab nws. Tom qab nruab, qhib lub configuration software, xaiv thiab qhib qhov chaw nres nkoj serial, nws yuav tso saib lub sij hawm tiag tiag roj concentration ntawm lub software.
Lub software tuaj yeem nyeem lub sijhawm tiag tiag ntawm cov pa roj, teeb tsa cov roj tsis muaj roj, ntsuas qhov ntsuas, nyeem cov ntaub ntawv ceeb toom, nyeem cov ntaub ntawv khaws cia hauv lub sijhawm, thiab lwm yam.
Yog tias tsis muaj cov qauv roj, thov tsis txhob nkag mus rau qhov kev ua haujlwm roj calibration.
● Qee tus nqi roj tsis yog 0 tom qab pib.
Vim tias cov ntaub ntawv roj tsis tau pib ua tiav, nws yuav tsum tau tos ib pliag. Rau ETO sensor, thaum lub roj teeb ntawm lub ntsuas hluav taws xob tsis muaj zog, ces tau them thiab rov pib dua, nws yuav tsum tau tos ob peb teev.
● Tom qab siv ob peb lub hlis, O2 concentration qis dua hauv ib puag ncig ib puag ncig.
Nkag mus rau hauv roj calibration interface thiab calibrate lub ntes nrog concentration 20.9.
● Lub computer tsis tuaj yeem paub qhov chaw nres nkoj USB.
Xyuas seb lub USB tsav puas tau teeb tsa thiab cov ntaub ntawv cable yog 4-core.
Cov sensors nrog lub neej ua haujlwm tsawg; nws tsis tuaj yeem kuaj ib txwm thiab xav tau hloov pauv tom qab siv nws lub sijhawm ua haujlwm. Nws yuav tsum tau calibrated txhua ib nrab xyoo nyob rau hauv lub sij hawm muab kev pab cuam los xyuas kom meej qhov tseeb. Standard gas rau calibration yog tsim nyog thiab yuav tsum tau.
● Thaum them nyiaj, thov kaw lub ntsuas ntsuas kom txuag lub sijhawm them. Tsis tas li ntawd, yog tias hloov thiab them nyiaj, lub sensor yuav raug cuam tshuam los ntawm qhov sib txawv ntawm lub charger (los yog qhov sib txawv ntawm qhov chaw them nyiaj), thiab nyob rau hauv qhov xwm txheej hnyav, tus nqi yuav tsis raug lossis txawm tias lub tswb.
● Nws xav tau 4-6 teev rau kev them nyiaj thaum lub ntsuas hluav taws xob pib lub hwj chim tawm.
● Tom qab tau txais tag nrho cov nqi, rau cov roj combustible, nws tuaj yeem ua haujlwm 24 teev tsis tu ncua (Tshwj tsis yog lub tswb nrov, vim tias thaum lub tswb nrov, nws kuj vibrate thiab flashing uas siv hluav taws xob thiab cov sij hawm ua haujlwm yuav yog 1/2 lossis 1/3 ntawm qhov qub.
● Thaum lub tshuab ntes nrog lub hwj chim qis, nws yuav pib lub hwj chim qhib / tawm ntau zaus, qhov twg nws yuav tsum tau them rau lub sijhawm.
● Tsis txhob siv lub tshuab ntes nyob rau hauv ib puag ncig corrosive.
● Tsis txhob kov dej.
● Them lub roj teeb txhua ib mus rau ob lub hlis los tiv thaiv nws lub neej ib txwm yog tias nws tsis siv ntev.
● Yog tias lub tshuab ntes poob lossis tsis tuaj yeem pib thaum siv, thov rub lub qhov rov pib dua rau saum lub cuab yeej nrog tus pas txhuam hniav lossis thimble kom tshem tawm qhov kev sib tsoo.
● Thov nco ntsoov pib lub tshuab hauv ib puag ncig ib puag ncig. Tom qab pib, coj mus rau qhov chaw uas yuav tsum tau kuaj xyuas cov pa roj tom qab kev pib ua tiav.
● Yog xav tau cov ntaub ntawv khaws cia muaj nuj nqi, nws yog qhov zoo dua rau nkag mus rau lub sijhawm teev cov ntawv qhia zaub mov ua ntej lub cuab yeej pib ua tiav tom qab pib, txhawm rau tiv thaiv lub sijhawm tsis meej pem thaum nyeem cov ntaub ntawv, txwv tsis pub, calibrating lub sij hawm tsis xav tau.
