Kauj ruam 3: Tom qab teeb tsa lub calibration, tuav lub khawm sab laug thiab txoj cai khawm, hloov lub interface rau cov roj calibration interface, raws li qhia nyob rau hauv daim duab 26, qhov interface no muaj ib tug tam sim no tus nqi kuaj pom roj concentration. Thaum lub countdown mus rau 10, koj tuaj yeem nias sab laug khawm rau phau ntawv calibration, tom qab 10S, cov roj tsis siv neeg calibrates, tom qab Calibration tiav, lub interface qhia 'calibration ua tiav! ' Ntawm qhov tsis sib xws Show' Calibration ua tsis tiav! '.Cov zaub hom qhia hauv daim duab 27.
Daim duab 26 Calibration Interface
Daim duab 27 Calibration tau tshwm sim
Kauj Ruam 4: Tom qab Calibration ua tiav, tus nqi ntawm cov roj yog tias cov zaub tsis ruaj khov, Koj tuaj yeem xaiv 'rescaled', yog tias qhov calibration ua tsis tiav, xyuas cov roj calibration thiab calibration chaw yog tib yam los yog tsis. Tom qab calibration ntawm cov roj ua kom tiav, nias txoj cai rov qab mus rau qhov ntsuas roj interface.
Kauj ruam 5: Tom qab tag nrho cov roj calibration tiav, nias cov ntawv qhia zaub mov kom rov qab mus rau qhov ntsuas roj interface, los yog cia li rov qab mus rau lub gas detection interface.
Rov qab
Hauv cov ntawv qhia zaub mov tseem ceeb, nias tus yuam sij sab laug kom xaiv cov khoom ua haujlwm 'rov qab', thiab tom qab ntawd nias lub pob sab xis kom rov qab mus rau cov ntawv qhia zaub mov dhau los
1) Nco ntsoov kom tsis txhob them lub sijhawm ntev. Lub sijhawm them nyiaj yuav txuas ntxiv mus, thiab lub ntsuas qhov ntsuas yuav cuam tshuam los ntawm qhov sib txawv ntawm lub charger (lossis them ib puag ncig qhov sib txawv) thaum lub ntsuas ntsuas qhib. Nyob rau hauv feem ntau cov mob hnyav, nws yuav txawm tshwm sim ntsuas qhov yuam kev tso saib lossis lub tswb.
2) Lub sij hawm them nqi ib txwm yog 3 mus rau 6 teev los yog li ntawd, sim tsis txhob them cov cuab yeej hauv 6 teev lossis ntau dua los tiv thaiv lub neej zoo ntawm lub roj teeb.
3) Lub ntsuas hluav taws xob tuaj yeem ua haujlwm rau 12 teev lossis yog li ntawd tom qab them tag nrho (tshwj tsis yog lub tswb lub xeev, vim tias lub flash thaum lub tswb nrov, kev vibration, suab xav tau lub zog ntxiv. Lub sijhawm ua haujlwm txo qis rau 1/2 txog 1/3 thaum tuav lub tswb. xwm txheej).
4) Thaum lub hwj chim ntawm lub ntsuas hluav taws xob qis heev, lub ntsuas hluav taws xob yuav raug qhib thiab kaw tsis tu ncua tsis tu ncua. Lub sijhawm no, nws yog ib qho tsim nyog yuav tau them cov ntsuas
5) Nco ntsoov tsis txhob siv cov cuab yeej hauv qhov chaw corrosive
6) Nco ntsoov kom tsis txhob sib cuag nrog cov cuab yeej dej.
7) Nws yuav tsum tau muab tshem tawm lub hwj chim cable, thiab them txhua 2-3 lub hlis, txhawm rau tiv thaiv lub roj teeb lub neej thaum tsis siv ntev.
8) Yog tias lub cuab yeej sib tsoo lossis tsis tuaj yeem qhib tau, koj tuaj yeem tshem tawm cov hlua hluav taws xob, tom qab ntawd ntsaws cov hlua hluav taws xob los daws qhov xwm txheej sib tsoo.
9) Xyuas kom tseeb tias cov ntsuas roj yog qhov qub thaum qhib lub ntsuas.
10) Yog tias koj xav tau nyeem cov ntaub ntawv ceeb toom, nws qhov zoo tshaj plaws nkag mus rau cov ntawv qhia zaub mov kom raug lub sijhawm ua ntej qhov pib ua tsis tiav los tiv thaiv kev ntxhov siab thaum nyeem cov ntaub ntawv.
