Momwe mungayesere capacitor ndi multimeter

Nthawi zambiri anthu amandifunsa momwe ndingayesere capacitor ndi multimeter.

Chikhalidwe cha capacitor ndi kulipira ndi kumasula mphamvu mofulumira kuposa batire chifukwa imasunga mphamvu mosiyana, ngakhale kuti sichikhoza kusunga ndalama zofanana. Izi ndizothandiza kwambiri ndichifukwa chake mutha kupeza capacitor pafupifupi PCB iliyonse.

Capacitor imasunga mphamvu zomwe zimatulutsidwa kuti zithetse kuzimitsa kwamagetsi.

Mkati mwa capacitor yayikulu, tili ndi mbale ziwiri zopangira, zomwe nthawi zambiri zimapangidwa ndi aluminiyamu, zolekanitsidwa ndi zida zoteteza dielectric monga ceramic.

Dielectric imatanthawuza kuti zinthuzo zidzasungunuka zikakhudzana ndi magetsi. Pa mbali ya capacitor, mudzapeza chizindikiro ndi bar kusonyeza mbali (terminal) ndi zoipa.

Njira zoyesera capacitor ndi multimeter

Choyamba muyenera kuonetsetsa kuti mukudziwa zomwe mukuchita. Werengani machenjezo mosamala musanagwiritse ntchito njira zoyesera za capacitor.

Muyenera kudziwanso njira zazikulu zolephera, zomwe zikutanthauza kulephera kwa capacitor, kuti mudziwe njira yoyesera yogwiritsira ntchito:

• Kuchepetsa mphamvu
• Kuwonongeka kwa dielectric (chifupifupifupi)
• Kutaya kulumikizana pakati pa mbale ndi mtovu
• kutayikira panopa
• Kuwonjezeka kwa ESR (kufanana kwa mndandanda wa kukana)

Yang'anani capacitor ndi multimeter ya digito

1. Chotsani capacitor kuchokera kumagetsi, kapena onetsetsani kuti waya umodzi watsekedwa.
2. Onetsetsani kuti capacitor yatulutsidwa kwathunthu. Izi zitha kutheka polumikiza materminal onse a capacitor ndi screwdriver.
3. Khazikitsani mita ku mtundu wa ohm (osachepera 1k ohm)
4. Lumikizani ma multimeter otsogolera ku ma capacitor terminals. Onetsetsani kuti mukulumikiza zabwino ku zabwino ndi zoyipa ku zoyipa.
5. Kauntala idzawonetsa manambala angapo kwa sekondi imodzi kenako ndikubwerera ku OL (mzere wotseguka). Kuyesera kulikonse mu gawo 3 kudzawonetsa zotsatira zofanana ndi zomwe zili mu sitepe iyi.
6. Ngati palibe kusintha, ndiye kuti capacitor yafa.

Onani capacitor mu capacitance mode.

Panjira iyi, mufunika mita ya capacitance pa multimeter, kapena multimeter yokhala ndi izi.

Njirayi ndi yabwino kuyesa ma capacitors ang'onoang'ono. Pakuyesa uku, sinthani ku mawonekedwe a kuchuluka.

1. Chotsani capacitor kuchokera kumagetsi, kapena onetsetsani kuti waya umodzi watsekedwa.
2. Onetsetsani kuti capacitor yatulutsidwa kwathunthu. Izi zitha kutheka polumikiza materminal onse a capacitor ndi screwdriver.
3. Sankhani "Capacity" pa chipangizo chanu.
4. Lumikizani ma multimeter otsogolera ku ma capacitor terminals.
5. Ngati kuwerenga kuli pafupi ndi mtengo womwe wasonyezedwa pabokosi la chidebe cha capacitor, zikutanthauza kuti capacitor ili bwino. Kuwerenga kungakhale kochepa kuposa mtengo weniweni wa capacitor, koma izi ndi zachilendo.
6. Ngati simuwerenga capacitance, kapena ngati mphamvuyo ndi yochepa kwambiri kuposa momwe kuwerenga kukuwonetsera, capacitor yafa ndipo iyenera kusinthidwa.

Yang'anani Capacitor yokhala ndi ma voltage test.

Iyi ndi njira ina yoyesera capacitor. Ma capacitor amasunga kusiyana komwe kungachitike pamitengo, yomwe ndi ma voltages.

A capacitor ali anode (positive voteji) ndi cathode (negative voteji).

Njira imodzi yoyesera capacitor ndiyo kulipiritsa ndi voteji ndiyeno kuwerengera pa cathode ndi anode. Kuti muchite izi, gwiritsani ntchito voteji nthawi zonse pazotuluka. Polarity ikufunika pano. Ngati capacitor ali zonse zabwino ndi zoipa materminal, ndi polarized capacitor imene voteji zabwino adzapita anode ndi voteji zoipa kwa cathode.

1. Chotsani capacitor kuchokera kumagetsi, kapena onetsetsani kuti waya umodzi watsekedwa.
2. Onetsetsani kuti capacitor yatulutsidwa kwathunthu. Izi zitha kutheka potsekereza materminal onse a capacitor ndi screwdriver, ngakhale ma capacitor akulu amatulutsidwa bwino pakunyamula.
3. Yang'anani mtundu wamagetsi womwe walembedwa pa capacitor.
4. Ikani magetsi, koma samalani kuti muwonetsetse kuti magetsi ndi ocheperapo kuposa omwe capacitor adavotera; mwachitsanzo, mungagwiritse ntchito batri ya 9 volt kuti mutengere 16 volt capacitor ndipo onetsetsani kuti mulumikizane ndi njira zabwino zomwe zimachokera ku capacitor ndipo zolakwika zimabweretsa zolakwika.
5. Limbani capacitor mumasekondi pang'ono
6. Chotsani gwero lamagetsi (batri)
7. Khazikitsani mita ku DC ndikulumikiza voltmeter ku capacitor, kulumikiza zabwino ndi zabwino ndi zoipa-zoipa.
8. Onani mtengo wamagetsi oyambira. Iyenera kukhala pafupi ndi magetsi omwe amagwiritsidwa ntchito ku capacitor. Izi zikutanthauza kuti capacitor ili bwino. Ngati kuwerenga kuli kochepa kwambiri, capacitor imatulutsidwa.

Voltmeter idzapereka kuwerenga uku kwa nthawi yochepa kwambiri chifukwa capacitor idzayamba kutuluka mofulumira kudzera mu voltmeter kupita ku 0 volts.
