Uphawu lwe-multimeter capacitance kanye nendlela yokulufunda

Ukulinganisa amandla ngokunembile kudinga imishini ebizayo, kodwa i-multimeter yedijithali noma ye-analog ingakunikeza umbono onzima. Lokhu okuthunyelwe kuchaza uphawu lwe-multimeter capacitance nokuthi lufundwa kanjani.

Uphawu lwe-multimeter capacitance "-| (-.”

Landela lezi zinyathelo ukuze ufunde uphawu lwe-multimeter's capacitance.

Okokuqala, vula i-analog yakho noma i-multimeter yedijithali. Faka ama-plug ezimbobeni ezifanele ku-multimeter. Bese uvula i-multimeter knob kuze kube yilapho ikhomba uphawu lwe-multimeter's capacitance. Okulandelayo, hlola ukuze ubone ukuthi i-DMM yakho inenkinobho ye-REL yini. Udinga ukuyicindezela ngokuhlukaniswa kwemikhondo yokuhlola. Okulandelayo, nqamula i-capacitor kusuka kumjikelezo. Bese uxhuma imikhondo yokuhlola kumatheminali e-capacitor. Shiya imikhondo yokuhlola lapho imizuzwana embalwa ukuze uvumele i-multimeter ukuthi inqume ngokuzenzakalelayo ububanzi obulungile.  

Yini umthamo?

Inani lamandla kagesi agcinwe entweni ibizwa nge-capacitance. Isibonelo esihle ama-capacitor kumasekethe kagesi.

Uphawu lwe-multimeter capacitance 

Enye yezimpawu ezivame ukusetshenziswa kakhulu yi-multimeter capacitance symbol. Awukwazi ukulinganisa amandla ngaphandle kokuthi wazi ukuthi yini ozoyifuna ku-DMM yakho. Ngakho luyini lolu phawu?

Uphawu lwe-multimeter capacitance “–| (-.”

Ungakala kanjani amandla nge-multimeter

1. Setha idivayisi yakho 

Vula i-analog yakho noma i-multimeter yedijithali. Faka ama-plug ezimbobeni ezifanele ku-multimeter. Intambo ebomvu ixhuma embobeni ephawulwe ngophawu lwe-multimeter's capacitance (–|(–). Xhuma intambo emnyama embobeni ephawulwe ngokuthi “COM”. (1)

2. Setha i-multimeter yedijithali ukukala amandla. 

Vula i-multimeter knob kuze kube yilapho ikhomba uphawu lwe-multimeter's capacitance. Wonke ama-multimeter asebenzisa lolu phawu - (–|(–). Uma usebenzisa enye i-multimeter, ungasebenzisa inkinobho ephuzi "yomsebenzi" ukuze usethe i-DMM ukuze ilinganise amandla. Qaphela ukuthi indawo yokudayela ye-multimeter ngayinye ivumela izilinganiso eziningi. Kulokhu, qiniseka ukuthi ucindezela umsebenzi ophuzi kuze kuvele uphawu lomthamo we-multimeter.

3. Vula imodi ye-REL

Hlola ukuthi i-multimeter yakho yedijithali inenkinobho ye-REL yini. Udinga ukuyicindezela ngokuhlukaniswa kwemikhondo yokuhlola. Lokhu kusetha kabusha amandla omkhondo wokuhlola, okungase kuphazamise izilinganiso ze-multimeter's capacitance.

Kuyadingeka? Kuphela uma ukala ama-capacitor amancane.

4. Nqamula i-capacitor kusekethe.

Awukwazi ukukala ama-farads ngenkathi i-capacitor isaxhunywe kusekethe. Qaphela lapho uphatha ama-capacitor njengoba ukuphatha okungalungile kungase kubangele ukushaqeka kukagesi. Uma unqamula i-capacitor kumjikelezo kagesi, gqoka izingubo zokuzivikela kanye nezinto zokusebenza ezifana nezibuko zokuphepha namagilavu ​​avikelayo.

5.Linganisa umthamo 

Bese uxhuma imikhondo yokuhlola kumatheminali e-capacitor. Shiya imikhondo yokuhlola lapho imizuzwana embalwa ukuze uvumele i-multimeter ukuthi inqume ngokuzenzakalelayo ububanzi obulungile. (2)

Manje usungakwazi ukufunda i-capacitive multimeter ukufundwa esikrinini. Uma inani lomthamo lidlula ububanzi bokulinganisa obushiwo, isibonisi sizobonisa i-OL. Okufanayo kufanele kwenzeke uma i-capacitor yakho inephutha.

Ukufingqa

Manje uyazi ukuthi ungalinganisa kanjani i-capacitance nge-multimeter. Sithemba ukuthi uzothola lo mhlahlandlela uwusizo uma usebenzisa i-multimeter yakho yedijithali ukukala amandla. Zizwe ukhululekile ukufunda ezinye iziqondiso zethu uma ubambeka. Sibale ezimbalwa ngezansi.
