Letšoao la bokhoni ba multimeter le mokhoa oa ho le bala

Litekanyo tse nepahetseng tsa capacitance li hloka lisebelisoa tse theko e boima, empa multimeter ea digital kapa analog e ka u fa mohopolo o thata. Poso ena e bua ka letšoao la multimeter capacitance le mokhoa oa ho le bala.

Letšoao la bokhoni ba multimeter «–| (-.”

Latela mehato e ka tlase ho bala letšoao la multimeter capacitance.

Qala ka ho bulela analog kapa multimeter ea hau ea dijithale. Kenya li-plug likoung tse nepahetseng ho multimeter. Ebe u fetola konopo ea multimeter ho fihlela e supa letšoao la multimeter capacitance. Ebe u hlahloba hore na DMM ea hau e na le konopo ea REL. U lokela ho tobetsa ho eona ka lihlopha tse arohaneng tsa liteko. Ka mor'a moo, tlosa capacitor ho tloha potolohong. Ebe o kopanya liteko tse lebisang ho li-terminals tsa capacitor. Tlohela lintlha tsa tlhahlobo moo metsotsoana e seng mekae hore multimeter e iketsetse sebaka se nepahetseng.  

Bokhoni ke eng?

Boholo ba matla a motlakase a bolokoang nthong e bitsoa matla. Mohlala o motle ke li-capacitor lipotolohong tsa elektroniki.

Letšoao la bokhoni ba multimeter 

E 'ngoe ea matšoao a sebelisoang haholo a multimeter ke letšoao la multimeter capacitance. U ke ke ua lekanya bokhoni ntle le haeba u tseba seo u se batlang ho DMM. Joale letšoao lee ke eng?

Letšoao la bokhoni ba Multimeter “–| (-.”

Mokhoa oa ho lekanya capacitance ka multimeter

1. Hlophisa sesebelisoa sa hau 

Bulela multimeter ea hau ea analog kapa ea digital. Kenya li-plug likoung tse nepahetseng ho multimeter. Hokela terata e khubelu boema-kepe bo tšoailoeng ka letšoao la matla la multimeter (–|(–). Hokela terata e ntšo boema-kepeng bo tšoailoeng “COM”. (1)

2. Theha DMM ho lekanya bokhoni. 

Fetola konopo ea multimeter ho fihlela e supa letšoao la matla a multimeter. Li-multimeter kaofela li sebelisa letšoao lena - (–|(–). Haeba u sebelisa multimeter e fapaneng, u ka sebelisa konopo ea ts'ebetso e mosehla ho seta DMM ho metha bokhoni. Hlokomela hore sebaka se seng le se seng sa ho daela sa multimeter se lumella litekanyo tse ngata. , Tabeng ena , hopola ho tobetsa ts'ebetso e mosehla ho fihlela letšoao la multimeter capacitance le hlaha.

3. Kenya tšebetsong mokhoa oa REL

Sheba hore na DMM ea hau e na le konopo ea REL. U lokela ho tobetsa ho eona ka lihlopha tse arohaneng tsa liteko. Sena se senya bokhoni ba liteko tsa liteko, tse ka 'nang tsa kena-kenana le tekanyo ea multimeter capacitance.

Hoa hlokahala? Ke feela ha u lekanya li-capacitor tse nyane.

4. Tlosa capacitor ho tloha potolohong.

Ha o khone ho lekanya li-farads ha capacitor e ntse e hokahane le potoloho. E-ba hlokolosi ha u tšoara li-capacitor kaha ho tšoara ka tsela e sa lokelang ho ka fella ka ho tsosoa ha motlakase. Ha u khaola capacitor ho potoloho ea motlakase, apara liaparo tse sireletsang le lisebelisoa tse kang likhalase tsa tšireletso le liatlana tse sireletsang.

5. Lekanya bokhoni 

Ebe o kopanya liteko tse lebisang ho li-terminals tsa capacitor. Tlohela lintlha tsa tlhahlobo moo metsotsoana e seng mekae hore multimeter e iketsetse sebaka se nepahetseng. (2)

Joale u ka bala 'malo oa multimeter oa capacitance skrineng. Haeba boleng ba capacitance bo feta tekanyo e behiloeng, ponts'o e tla bontša OL. Ho lokela ho etsahala se tšoanang haeba capacitor ea hau e fosahetse.

Ho akaretsa

Hona joale o tseba ho lekanya bokhoni ba multimeter. Re tšepa hore tataiso ena e tla u thusa ha u sebelisa DMM ho metha bokhoni. Ikutloe u lokolohile ho bala litataiso tse ling tsa rona haeba u ka ts'oara. Re thathamisitse tse seng kae ka tlase.

• Tafole ea matšoao a Multimeter
• Mokhoa oa ho Sebelisa Multimeter ea Cen-Tech Digital ho Lekola Voltage
• Mokhoa oa ho lekola spark plug ka multimeter
