Yadda ake amfani da multimita don dummies

Motocin zamani ba za su iya yin ba tare da lantarki ba; ƙari kuma, ana cika su kawai da da'irorin lantarki da na'urori. Don bincika saurin aiki a cikin da'irorin lantarki na mota, aƙalla za ku buƙaci na'ura kamar multimeter.

A cikin wannan labarin, zamuyi la'akari da sauye-sauye na yau da kullun kuma zamuyi cikakken bayani akan yadda ake amfani da multimita don dummies, watau ga waɗanda ba su taɓa riƙe wannan na'urar a hannunsu ba, amma za su so su koya.

Bidiyo yadda ake amfani da multimeter

Multimita. Yadda ake amfani da multimeter. Gwaji. Kammalallen umarni kan yadda ake amfani da magwajin.

Babban masu haɗawa da ayyuka na multimeter

Don ƙarin fahimtar abin da ke cikin gungumen azaba, za mu ba da hoto na multimeter na gani da nazarin hanyoyin da mahaɗan.

Bari mu fara da masu haɗawa inda za'a haɗa wayoyi. Ana haɗa baƙin waya zuwa mahaɗin da ake kira COM (COMMON, wanda ke nufin gama gari a fassarar). Bakin waya a koyaushe ana haɗa ta kawai ga wannan mahaɗin, ba kamar mai ja ba, wanda a mafi yawan lokuta yana da mahaɗi 2 don haɗi:

• Mai haɗa VRmA - ana amfani dashi don auna ƙarfin lantarki, juriya da igiyoyi sama da 10 A (Amps);
• 10A mai haɗawa - ana amfani dashi don auna igiyoyi har zuwa 10 A.

Ayyuka da jeri na multimeter

A kusa da maɓallin tsakiya zaka iya ganin jeri tsakanin fararrun zane, bari mu ragargaji kowane ɗayansu:

• DCV - (DC - kai tsaye halin yanzu, V - ƙarfin lantarki) ta amfani da wannan kewayon, DC ƙarfin lantarki ana auna. Ana nuna volts da millivolts akan ma'auni;
• ACV - (AC - alternating current, V - voltage) Ana auna wutar lantarki ta AC daidai;
• DCA - (DC - kai tsaye halin yanzu, A - Amps) ma'auni na kai tsaye (ana nuna kewayon daga 200 microamps zuwa 200 milliamps akan na'urar);
• 10A - kewayon ma'auni daban don babban halin yanzu kai tsaye, don wannan ya zama dole don sake shirya jajayen waya zuwa mai haɗin sama;
•  hFE - yanayin gwajin transistor;
• Omega - iyakar ma'aunin juriya.

Batirin DC ƙarfin ƙarfin lantarki

Bari mu ba da kwatancen misali na yadda ake amfani da multimeter, wato, za mu auna ƙarfin DC na batirin al'ada.

Tunda farko mun san cewa ƙarfin DC a cikin batirin ya kai 1,5 V, nan da nan za mu iya saita sauya zuwa 20 V.

Muhimmin! Idan baku san ƙarfin DC ɗin a cikin kayan aiki ko naúrar da aka auna ba, ya kamata koyaushe saita sauya zuwa matsakaicin ƙimar kewayon da ake so kuma ku saukar da shi kamar yadda ya dace don rage kuskure.

Mun kunna yanayin da ake so, je kai tsaye zuwa ma'auni, yi amfani da binciken ja zuwa gefen baturi mai kyau, da kuma binciken baƙar fata zuwa gefen mara kyau - muna kallon sakamakon akan allon (ya kamata ya nuna sakamakon 1,4-). 1,6 V, dangane da yanayin baturi).

Fasali na auna wutar AC

Bari muyi kusa da abin da kuke buƙatar kulawa idan kun auna ƙarfin AC.

Kafin fara aiki, ka tabbata ka bincika ko wadanne mahada aka saka wayoyi a ciki, saboda idan, yayin da ake auna wata hanyar ta daban, an saka jan waya a cikin mahaɗin don auna naúrar (10 A connector), gajerun hanyoyin zai faru, wanda ba shi da kyau .

Sake, idan baku san iyakar ƙarfin AC ba, sa'annan kunna juya zuwa matsakaicin matsayi.

Misali, a cikin gida, mun san cewa ƙarfin lantarki a cikin kwasfa da kayan lantarki kusan 220 V ne, bi da bi, akan na'urar zaka iya saita 500 V daga layin ACV lafiya.

Yadda za a auna yoyon kwance a cikin mota tare da multimeter

Bari mu duba yadda za a auna yawan zubewar a cikin mota ta amfani da multimeter. Cire haɗin duk wutar lantarki tukunna kuma cire maɓallin daga maɓallin kunnawa. Na gaba, kana buƙatar jefar da mummunan tashar daga baturin (ka bar mahimmin tashar ba canzawa). Muna nuna multimeter zuwa yanayin auna ma'aunin 10 A DC. Kar ka manta da sake tsara jan waya a cikin mai haɗawa daidai (na sama, daidai da 10 A). Muna haɗa bincike ɗaya zuwa tashar akan wayar da ta yanke, kuma na biyu kai tsaye zuwa mummunan baturin.

Bayan jira kadan don ƙimomin su daina tsalle, za ku ga halin ƙazantaccen ɓarke ​​a cikin motarku.

Mene ne karɓaɓɓiyar ƙimar zubar

• Mafi ƙarancin darajar da za a karɓa ita ce 15 MA;
• Matsakaicin ƙimar zubar ruwa a cikin motar ita ce 70 MA.

Idan iyakar darajar ku ta wuce, to kuna buƙatar zuwa bincika ɓoyewa. Duk wani kayan lantarki a cikin mota na iya haifar da malala.

Asalin ƙa'idar binciken shine a sake zare fis ɗin kuma a duba ƙimar yabo. Idan kun cire fis ɗin kuma ƙimar yabo akan na'urar bai canza ba, to komai yayi kyau tare da na'urar da wannan fuse ke da alhakin. Kuma idan, bayan cirewa, ƙimar ta fara tsalle, to, wani abu ba daidai ba ne tare da na'urar da ta dace.

Tambayoyi & Amsa:

Yadda za a auna ƙarfin lantarki tare da multimeter? An saita yanayin ma'aunin wutar lantarki, saita iyakar ma'auni (a cikin motoci, wannan alamar ita ce 20V), kuma yana da mahimmanci don zaɓar yanayin ma'aunin DC.

Ta yaya Ci gaba ke aiki akan Multimeter? Multimeter yana da tushen wutar lantarki ɗaya ɗaya (allon yana da ƙarfin baturi). A kan sashin da aka gwada na wayoyi, an ƙirƙiri wani ɗan ƙaramin ƙima kuma ana yin rikodi (ko an rufe hulɗar tsakanin binciken ko a'a).
