Mokhoa oa ho lekola capacitor ka multimeter

Hangata batho ba mpotsa hore na nka leka capacitor joang ka multimeter.

Sebopeho sa capacitor ke ho tjhaja le ho lokolla matla ka potlako ho feta betri hobane e boloka matla ka tsela e fapaneng, le hoja e ke ke ea boloka chelete e lekanang. Sena se bohlokoa haholo ke ka lebaka leo u ka fumanang capacitor hoo e batlang e le PCB e 'ngoe le e' ngoe.

Capacitor e boloka matla a lokollotsoeng ho fokotsa ho tima ha motlakase.

Ka har'a capacitor e kholo, re na le lipoleiti tse peli tsa conductive, hangata tse entsoeng ka aluminium, tse arohaneng ka lisebelisoa tsa ho thibela dielectric tse kang ceramic.

Dielectric e bolela hore thepa e tla polarze ha e kopana le tšimo ea motlakase. Ka lehlakoreng la capacitor, u tla fumana letšoao le bar e bontšang hore na ke lehlakore lefe (terminal) le fosahetseng.

Mekhoa ea ho lekola capacitor ka multimeter

Pele u lokela ho etsa bonnete ba hore u tseba seo u se etsang. Bala litemoso ka hloko pele u sebelisa mekhoa ena ea tlhahlobo ea capacitor.

U lokela hape ho tseba mekhoa ea mantlha ea ho hloleha, ho bolelang ho hloleha ho belaelloang ha capacitor, kahoo o ka tseba hore na o sebelisa mokhoa ofe oa tlhahlobo:

• Phokotso ea bokhoni
• Ho robeha ha dielectric (potoloho e khuts'oane)
• Ho lahleheloa ke kamano pakeng tsa poleiti le loto
• leakage current
• ESR e eketsehileng (e lekanang letoto la ho hanyetsa)

Sheba capacitor ka multimeter ea digital

1. Hakolla capacitor phepelong ea motlakase, kapa bonyane etsa bonnete ba hore terata e le 'ngoe e khaotsoe.
2. Etsa bonnete ba hore capacitor e felile ka ho feletseng. Sena se ka finyelloa ka ho hokahanya li-terminals ka bobeli tsa capacitor le screwdriver.
3. Beha metara ho ohm range (bonyane 1k ohm)
4. Hokela multimeter ho isa ho li-terminals tsa capacitor. Etsa bonnete ba hore o hokahanya positive, negative le negative.
5. Khaontareng e tla bontša linomoro tse 'maloa motsotsoana ebe e khutlela hang-hang ho OL (mohala o bulehileng). Boiteko bo bong le bo bong mohatong oa 3 bo tla bonts'a sephetho se ts'oanang le mohatong ona.
6. Haeba ho se na phetoho, joale capacitor e shoele.

Sheba capacitor ka mokhoa oa capacitance.

Bakeng sa mokhoa ona, o tla hloka meter ea capacitance ho multimeter, kapa multimeter e nang le tšobotsi ena.

Mokhoa ona o molemo ka ho fetisisa bakeng sa ho hlahloba li-capacitor tse nyenyane. Bakeng sa teko ena, fetohela ho mokhoa oa bokhoni.

1. Hakolla capacitor phepelong ea motlakase, kapa bonyane etsa bonnete ba hore terata e le 'ngoe e khaotsoe.
2. Etsa bonnete ba hore capacitor e felile ka ho feletseng. Sena se ka finyelloa ka ho hokahanya li-terminals ka bobeli tsa capacitor le screwdriver.
3. Khetha "Capacity" sesebelisoa sa hau.
4. Hokela multimeter ho isa ho li-terminals tsa capacitor.
5. Haeba ho bala ho le haufi le boleng bo bontšitsoeng lebokoseng la setshelo sa capacitor, ho bolela hore capacitor e boemong bo botle. Ho bala ho ka ba tlase ho boleng ba sebele ba capacitor, empa sena se tloaelehile.
6. Haeba u sa bale capacitance, kapa haeba bokhoni bo le tlase haholo ho feta kamoo ho bala ho bontšang kateng, capacitor e shoele 'me e lokela ho nkeloa sebaka.

Lekola Capacitor e nang le teko ea motlakase.

Ena ke tsela e 'ngoe ea ho hlahloba capacitor. Li-capacitor li boloka liphapang tse ka bang teng ka litefiso, e leng li-voltage.

Capacitor e na le anode (positive voltage) le cathode (negative voltage).

Tsela e 'ngoe ea ho hlahloba capacitor ke ho e tjhaja ka motlakase ebe o bala ho cathode le anode. Ho etsa sena, sebelisa voltage kamehla ho lihlahisoa. Polarity e bohlokoa mona. Haeba capacitor e na le li-terminals tse ntle le tse mpe, ke polarized capacitor eo ho eona motlakase o motle o tla ea ho anode le matla a fosahetseng ho cathode.

1. Hakolla capacitor phepelong ea motlakase, kapa bonyane etsa bonnete ba hore terata e le 'ngoe e khaotsoe.
2. Etsa bonnete ba hore capacitor e felile ka ho feletseng. Sena se ka finyelloa ka ho koala li-terminals ka bobeli tsa capacitor ka screwdriver, le hoja li-capacitor tse kholo li ka lokolloa hantle ka mojaro.
3. Sheba lebelo la motlakase le tšoailoeng ho capacitor.
4. Etsa kopo ea motlakase, empa e-ba hlokolosi ho etsa bonnete ba hore motlakase o tlase ho feta seo capacitor e lekantsoeng ka sona; mohlala, o ka sebelisa betri ea 9 volt ho lefella 16 volt capacitor 'me u be le bonnete ba hore u kopanya mekhoa e metle ho ea ho mekhoa e metle ea capacitor' me e mpe e lebisa ho mekhoa e mebe.
5. Laela capacitor ka metsotsoana e seng mekae
6. Tlosa mohloli oa motlakase (betri)
7. Beha meter ho DC 'me u kopanye voltmeter ho capacitor, ho kopanya positive-to-positive le negative-to-negative.
8. Sheba boleng ba voltage ea pele. E lokela ho ba haufi le motlakase o sebelisoang ho capacitor. Sena se bolela hore capacitor e boemong bo botle. Haeba ho bala ho le tlase haholo, capacitor e lokolloa.

Voltmeter e tla bontša 'malo ona ka nako e khutšoanyane haholo hobane capacitor e tla tsoa ka potlako ka voltmeter ho 0V.
