Yuav kom sim lub roj teeb charger rau lub rooj zaum muaj log, koj yuav tsum tau siv lub multimeter los ntsuas qhov hluav taws xob ntawm lub charger thiab xyuas kom meej tias nws ua haujlwm zoo. Nov yog cov lus qhia ib kauj ruam zuj zus:
1. Sau Cov Cuab Yeej
- Multimeter (los ntsuas qhov voltage).
- Lub tshuab them roj teeb rau lub rooj zaum muaj log.
- Lub roj teeb rau lub rooj zaum muaj log uas them tag lawm los yog txuas nrog lawm (xaiv tau rau kev kuaj xyuas qhov hnyav).
2. Tshawb xyuas qhov tso zis ntawm lub Charger
- Tua thiab tshem lub charger tawmUa ntej koj pib, xyuas kom tseeb tias lub charger tsis txuas nrog lub hwj chim.
- Teem lub multimeter: Hloov lub multimeter mus rau qhov chaw teeb tsa DC voltage tsim nyog, feem ntau siab dua li qhov tso zis ntsuas ntawm lub charger (piv txwv li, 24V, 36V).
- Nrhiav cov qhov txuas ntawm cov zisNrhiav cov qhov zoo (+) thiab qhov tsis zoo (-) ntawm lub qhov hluav taws xob charger.
3. Ntsuas Qhov Voltage
- Txuas cov multimeter probes: Kov lub multimeter probe liab (positive) rau lub positive terminal thiab lub dub (negative) probe rau lub negative terminal ntawm lub charger.
- Ntsaws lub charger rau hauv: Ntsaws lub charger rau hauv lub qhov hluav taws xob (tsis txhob txuas nws rau lub rooj zaum muaj log) thiab saib qhov nyeem ntawm multimeter.
- Piv txwv qhov kev nyeem ntawvQhov nyeem hluav taws xob yuav tsum phim qhov ntsuas tso zis ntawm lub charger (feem ntau yog 24V lossis 36V rau cov charger rooj zaum muaj log). Yog tias qhov hluav taws xob qis dua qhov xav tau lossis xoom, lub charger yuav tsis ua haujlwm.
4. Kev Ntsuas Hauv Qab Load (Xaiv Tau)
- Txuas lub charger rau lub roj teeb ntawm lub rooj zaum muaj log.
- Ntsuas qhov hluav taws xob ntawm cov qhov kawg ntawm lub roj teeb thaum lub charger tseem ntsaws rau hauv. Qhov hluav taws xob yuav tsum nce me ntsis yog tias lub charger ua haujlwm zoo.
5. Tshawb xyuas cov teeb LED qhia
- Feem ntau cov charger muaj teeb qhia seb nws puas them lossis them tag. Yog tias cov teeb tsis ua haujlwm raws li qhov xav tau, nws yuav yog ib qho cim qhia tias muaj teeb meem.
Cov cim qhia ntawm lub Charger Faulty
- Tsis muaj qhov tso zis voltage lossis qhov hluav taws xob qis heev.
- Cov teeb liab LED ntawm lub charger tsis ci.
- Lub roj teeb tsis them txawm tias txuas ntev lawm los xij.
Yog tias lub charger tsis ua tiav ib qho ntawm cov kev sim no, nws yuav tsum tau hloov lossis kho.
