Txhawm rau kuaj lub rooj zaum lub rooj zaum roj teeb, koj yuav xav tau lub tshuab hluav taws xob los ntsuas lub charger qhov hluav taws xob tso zis thiab xyuas kom meej tias nws ua haujlwm zoo. Ntawm no yog ib daim ntawv qhia step-by-step:
1. Sau Cov Cuab Yeej
- Multimeter (los ntsuas qhov voltage).
- Wheelchair roj teeb charger.
- Them tag nrho los yog txuas lub rooj zaum lub rooj zaum roj teeb (yeem xaiv rau kev kuaj xyuas).
2. Xyuas lub Charger's Output
- Tua tawm thiab tshem tawm lub charger: Ua ntej koj pib, xyuas kom lub charger tsis txuas nrog lub hwj chim.
- Teem lub multimeter: Hloov lub multimeter mus rau qhov tsim nyog DC voltage qhov chaw, feem ntau siab tshaj lub charger cov zis tso zis (piv txwv li, 24V, 36V).
- Nrhiav cov zis connectors: Nrhiav qhov zoo (+) thiab qhov tsis zoo (-) terminals ntawm lub charger plug.
3. Ntsuas qhov Voltage
- Txuas lub multimeter probes: Kov qhov liab (zoo) multimeter sojntsuam mus rau qhov zoo davhlau ya nyob twg thiab qhov dub (tsis zoo) sojntsuam rau qhov tsis zoo ntawm lub charger.
- Txuas lub charger: Txuas lub charger rau hauv lub qhov hluav taws xob hluav taws xob (tsis txuas rau lub rooj zaum log) thiab saib xyuas qhov kev nyeem ntawv multimeter.
- Muab piv rau kev nyeem ntawv: Qhov kev nyeem ntawv voltage yuav tsum phim lub charger cov zis ntsuas (feem ntau 24V lossis 36V rau lub rooj zaum lub rooj zaum). Yog tias qhov hluav taws xob qis dua li qhov xav tau lossis xoom, lub charger tuaj yeem ua yuam kev.
4. Test Hauv Load (Yeem)
- Txuas lub charger rau lub rooj zaum lub rooj zaum lub roj teeb.
- Ntsuas qhov voltage ntawm lub roj teeb terminals thaum lub charger ntsaws. Qhov voltage yuav tsum nce me ntsis yog tias lub charger ua haujlwm zoo.
5. Txheeb xyuas qhov taw qhia LED teeb
- Feem ntau cov chargers muaj qhov taw qhia teeb uas qhia seb nws puas tau them lossis them tag nrho. Yog tias lub teeb tsis ua haujlwm raws li qhov xav tau, nws yuav yog ib qho teeb meem.
Cov cim qhia ntawm Faulty Charger
- Tsis muaj qhov hluav taws xob tso tawm lossis hluav taws xob tsawg heev.
- Lub charger's LED qhia tsis teeb.
- Lub roj teeb tsis tau them txawm tias tom qab ncua sij hawm txuas nrog.
Yog tias lub charger ua tsis tiav ib qho ntawm cov kev sim no, nws yuav tsum tau hloov lossis kho.
