Muaj nuj nqi
| No | Muaj nuj nqi | Kev piav qhia |
| 1 | Kov khawm | Nws tuaj yeem siv rau kev saib xyuas ze-kawg, thiab tuaj yeem ua rau NB qhia.Nws siv txoj kev kov capacitive, qhov kov rhiab heev. |
| 2 | Kev txij nkawm nyob ze | Nws tuaj yeem siv rau ntawm qhov chaw saib xyuas ntawm lub module, nrog rau kev teeb tsa kev teeb tsa, nyeem cov ntaub ntawv, hloov kho firmware thiab lwm yam. Nws siv txoj kev sib txuas lus infrared, uas tuaj yeem ua haujlwm los ntawm lub khoos phis tawj lossis lub PC host computer. |
| 3 | NB kev sib txuas lus | Lub module cuam tshuam nrog lub platform los ntawm NB network. |
| 4 | Kev ntsuas | Txais cov txheej txheem tsis sib nqus inductance metering, txhawb nqa pem hauv ntej thiab rov qab ntsuas |
| 5 | Disassembly tswb | Lub disassembly tswb muaj nuj nqi yog neeg xiam los ntawm lub neej ntawd thaum lub meter module yog powered rau.Tom qab kev teeb tsa thiab 10L metering, lub tswb nrov disassembly yuav muaj.Thaum lub module tawm ntawm lub 'meter' rau li 2s, lub tswb disassembly thiab keeb kwm disassembly tswb yuav tshwm sim thiab ua rau NB qhia.Reinstall lub module thiab lub 'meter' ib txwm ntsuas 10L, lub tswb disassembly yuav tau txais tshem tawm nyob rau hauv 3s, thiab lub disassembly yuav restarted tswb muaj nuj nqi.Lub tswb disassembly keeb kwm yuav raug muab tso tseg tsuas yog tom qab ua tiav nrog kev sib txuas lus module rau 3 zaug. |
| 6 | Magnetic nres tswb | Thaum cov hlau nplaum nyob ze rau ntawm Magnetoresistive element ntawm lub ntsuas ntsuas, kev sib nqus nres thiab keeb kwm sib nqus nres yuav tshwm sim.Tom qab tshem tawm cov hlau nplaum, qhov sib nqus nres yuav raug muab tso tseg.Cov keeb kwm sib nqus nres yuav tsuas yog muab tso tseg tom qab cov ntaub ntawv tau tshaj tawm rau lub platform. |
