Hauv cov ntawv qhia zaub mov tseem ceeb, nias lub pob laug los xaiv 'Rov qab', thiab tom qab ntawd nias lub pob txoj cai rov qab mus rau cov ntawv qhia zaub mov dhau los.
1. Nco ntsoov kom tsis txhob them nyiaj ntev.Thaum them nyiaj, thov ua kom lub ntsuas hluav taws xob nyob rau hauv lub xeev tawm, koj tuaj yeem ua kom lub sijhawm them nyiaj txo, thiab tom qab ntawd them nyiaj hauv lub xeev, lub ntsuas ntsuas lub ntsuas yuav raug rau qhov sib txawv ntawm lub charger (los yog them ib puag ncig sib txawv), thaum muaj xwm txheej hnyav. , qhov ntsuas yuav tshwm sim qhia tus nqi uas tsis raug lossis txawm tias nyob hauv lub tswb.
2. Cov cuab yeej siv hluav taws xob raug kaw tom qab kaw tsis siv neeg, lub sijhawm them ib txwm ntawm 3 mus rau 6 teev lossis yog li ntawd, sim tsis txhob ua kom lub ntsuas hluav taws xob ntau dua 6 teev los tiv thaiv lub roj teeb ntawm lub neej zoo ntawm lub roj teeb. .
3. Tom qab lub ntsuas hluav taws xob tau them tag nrho, lub sijhawm ua haujlwm tsis tu ncua yog cuam tshuam nrog kev qhib thiab lub tswb ntawm lub twj tso kua mis.(Vim yog qhib lub twj tso kua mis, lub tswb thaum lub teeb nyem, vibration, suab xav tau kev siv hluav taws xob ntxiv, tau lub tswb nrov, lub sijhawm ua haujlwm mus rau qhov qub 1/2 txog 1/3).
4. Ib txwm siv lub cuab yeej nyob rau hauv ib puag ncig corrosive.
5. Nco ntsoov zam kev sib cuag nrog lub ntsuas.
6. Nws yog ib qho tsim nyog kom tshem tawm cov hlua hluav taws xob ntev ntev, lossis kom them lub roj teeb ib zaug txhua 1 mus rau 2 lub hlis los tiv thaiv lub roj teeb lub neej ib txwm muaj.
7. Yog tias koj siv cov txheej txheem, kev sib tsoo lossis tsis tuaj yeem khau raj, hauv qab ntawm lub ntsuas hauv qab lub qhov me me, nrog rau sab saum toj ntawm rab koob, koj tuaj yeem ua tau.
8. Thov nco ntsoov tias cov ntsuas roj yog ib txwm nyob rau hauv cov ntaub ntawv ntawm khau raj, tom qab pib lub cuab yeej tom qab pib ua tiav kom nqa qhov chaw los kuaj xyuas cov roj.
9. Txhawm rau siv cov ntaub ntawv khaws cia muaj nuj nqi, nws yog qhov zoo tshaj plaws los pib lub cuab yeej tom qab kev pib ua tsis tiav ua ntej nkag mus rau lub sijhawm ua zaub mov calibration los tiv thaiv lub sijhawm los nyeem cov ntaub ntawv chaos.Tsis tas li ntawd tsis tas yuav kho lub sijhawm.
