Uluvivinya Kanjani Intambo Ephansi Yemoto Nge-Multimeter (Umhlahlandlela)

Ukufakwa phansi okunephutha ngokuvamile kuyimbangela yezinkinga zikagesi. Ukubekwa phansi okunephutha kungadala umsindo wesistimu yomsindo. Kungase futhi kuholele ekushiseni ngokweqile kwamaphampu kaphethiloli kagesi noma umfutho ophansi, kanye nokuziphatha okuxakile kokulawula injini kagesi.

I-DMM iwumugqa wakho wokuqala wokuzivikela wokuhlola intambo yaphansi nokunquma ukuthi ingabe iwumthombo wenkinga. 

Endleleni, sizobheka kabanzi indlela yokuhlola ucingo oluphansi lwemoto nge-multimeter.

Ungahlola kanjani ukumiswa kwemoto nge-multimeter

Abantu abaningi bacabanga ukuthi i-accessory isekelwe uma ucingo lwaphansi luthinta noma iyiphi ingxenye yemoto. Akulungile. Kufanele unamathisele ucingo oluphansi endaweni engenapende, ukugqwala, noma ukunamathela. Upende osemaphaneli omzimba kanye nenjini usebenza njengesivikelo, okuholela ekusekelweni okungekuhle. (1)

No. 1. Isesekeli Test

• Xhuma intambo yaphansi ngokuqondile kuhlaka lwejeneretha. 
• Qinisekisa ukuthi akukho ukungcola phakathi kwesiqalisi nendawo yokufaka indawo yenjini. 

No. 2. Ukuhlolwa kokumelana

• Setha i-multimeter yedijithali ukukala ukumelana futhi uhlole isisetshenziswa setheminali esinegethivu yebhethri kanye nokuxhumeka okuphansi. 
• Ukubeka phansi kuphephile uma inani lingaphansi kwama-ohm amahlanu.

#3.Ukuhlolwa kwe-Voltage 

1. Khipha ukuxhumana.
2. Landela izintambo.
3. Vula umlilo wemoto.
4. Setha i-multimeter ku-DC voltage. 
5. Vula umlomo wombhobho bese uphinda indlela yaphansi njengoba kushiwo ngaphambili.
6. I-voltage akufanele ibe ngaphezu kwama-volts angu-05 ngaphansi komthwalo.
7. Uma uthola indawo lapho kunokwehla kwamandla kagesi, kufanele wengeze ucingo lwe-jumper noma uthole indawo entsha yomhlabathi. Lokhu kuqinisekisa ukuthi awekho ukwehla kwamandla kagesi kunoma yimaphi amaphuzu aphansi.

#4 Hlola indlela yaphansi phakathi kwezisetshenziswa nebhethri

• Ukuqala ngebhethri, hambisa umkhondo we-multimeter uye endaweni yokuqala, ngokuvamile i-fender ezimotweni ezinamandla. 
• Qhubeka kuze kube yilapho iphiko lixhuma emzimbeni oyinhloko bese lifinyelela ku-accessory. Uma uthola indawo yokumelana okuphezulu (ngaphezu kwama-ohm amahlanu), udinga ukuchofoza amaphaneli noma izingxenye nge-jumper noma ucingo.

Yini okufanele i-multimeter ibonise ocingweni lwaphansi?

Ku-multimeter, ikhebula eliphansi lomsindo wemoto kufanele libonise ukumelana okungu-0.

Uma ukuxhumana okuphansi phakathi kwebhethri yemoto nendawo ethile emotweni kunephutha, uzobona ukumelana okuphansi. Ihluka kusuka kuma-ohm ambalwa kuya ku-10 ohms.

Lokhu kusho ukuthi ukuqiniswa okwengeziwe noma ukuhlanzwa koxhumano kungadingeka. Lokhu kuqinisekisa ukuthi intambo yaphansi ithintana ngqo nensimbi engenalutho. (2)

Kodwa-ke, ngezikhathi ezingavamile ungathola amanani anengqondo we-30 ohms noma ngaphezulu. Lokhu kusho ukuthi kufanele uphinde umise ukuxhumana okuphansi ngokufaka indawo yokuxhumana ephansi. Ungakwazi futhi ukuxhuma intambo yaphansi ngqo ebhethrini.

Indlela yokuhlola ucingo oluhle lomhlabathi nge-multimeter

Isistimu yomsindo wemoto enikwa amandla umsakazo wemoto kanye ne-amplifier enendawo enephutha ngeke isebenze kahle.

I-multimeter iyithuluzi elingcono kakhulu lokuhlola izindawo ezihlukahlukene zomhlabathi ohlakeni lwemoto. I-multimeter kufanele inikeze amandla okuhlola ukumelana (ohms) futhi le nombolo izohluka kuye ngokuthi ulinganisa kuphi.

Isibonelo, indawo engaphansi kwebhulokhi yenjini ingase ibe phansi uma kuqhathaniswa, kodwa inhlabathi esesixhumi sebhande lesihlalo esingemuva ingaba phezulu kakhulu.

Imiyalo engezansi izokufundisa ukuthi ungasebenzisa kanjani i-multimeter ukuhlola uxhumo oluphansi lwemoto yakho.

1. Ngaphambi kokuqala ukuhlola, qiniseka ukuthi itheminali enegethivu yebhethri yemoto ixhunywe ebhethrini.
2. Vala noma yiziphi izisetshenziswa emotweni ezingase zidonse amandla amaningi ebhethri.
3. Setha i-multimeter kububanzi be-ohm bese ufaka i-probe eyodwa kutheminali enegethivu yebhethri lemoto.
4. Thatha i-probe yesibili futhi uyibeke lapho ufuna ukukala khona indawo ephansi ohlakeni lwemoto.
5. Hlola izindawo ezimbalwa eduze kwe-amplifier ebekiwe. 
6. Thatha amanothi ngokucophelela mayelana nesilinganiso ngasinye. Ukubeka phansi kufanele kube kuhle ngangokunokwenzeka, ikakhulukazi ku-amplifier enamandla. Ngakho-ke, ngokulandelayo khetha indawo enokumelana okulinganiselwe okuphansi kakhulu.

ICEBISO: Ungalulungisa kanjani ucingo lwaphansi olubi emotweni yakho

Uma ukuhlolwa kuqinisekisa ukuthi intambo yaphansi inesici, ungathintana nochwepheshe noma uzilungise ngokwakho. Naphezu kwalokhu, ukulungisa ucingo lomhlabathi olungalungile kuyindlela elula. Izindlela ezilandelayo zizokusiza ukuxazulula inkinga.

No. 1. Hlola Oxhumana Nabo

Umthombo wenkinga kungaba uxhumo oluvulekile (noma olungaphelele) kunoma yikuphi ukuphela kwentambo yaphansi. Ukuze uqiniseke, thola iziphetho zentambo. Uma zikhululekile, i-screwdriver noma i-wrench izokwanela. Shintshanisa noma yiziphi izikulufu ezigugile, amabhawudi noma amantongomane.

#2 Hlanza Oxhumana Nabo Abagqwalile noma Abagqwalile kanye Nezindawo

Sebenzisa ifayela noma i-sandpaper ukuhlanza noma yiziphi izindawo ezigqwalile noma ezigqwalile. Ukuxhunywa kwebhethri, iziphetho zezintambo, amabhawodi, amantongomane, izikulufu, namawasha konke kuyizindawo okufanele uzibheke.

No. 3. Shintsha intambo yaphansi 

Uma usuthole ucingo oluphansi, luhlolele ukusikeka, izinyembezi, noma ukuphuka. Thenga ukumiselela kwekhwalithi.

No. 4. Qedela intambo yaphansi

Isixazululo sokugcina nesilula ukungeza enye intambo yaphansi. Lokhu kuyisinqumo esihle uma okwangempela kunzima ukukuthola noma ukushintshwa. Kuhle ukuba nekhwalithi ephezulu yocingo lwaphansi lwamahhala ukuze uqinise indawo yemoto yakho.

Ukufingqa

Manje uyazi ukuthi ungabheka kanjani isisindo semoto nge-multimeter emotweni. Nokho, kufanele ugcine lawa maphuzu engqondweni, njengokuphepha futhi ungawaxhumi womabili ama-probe e-multimeter kumatheminali ebhethri.

I-multimeter izokhombisa ukumelana okuphansi okungaba ngu-0 ohms uma indawo yakho yaphansi ILUNGILE. Uma kungenjalo, uzodinga ukuthola elinye iphoyinti lokuzinza noma uxhume intambo yaphansi ngokuqondile ukusuka kubhethri ukuya ku-amplifier.

Ngezansi sibhale imihlahlandlela embalwa yokufunda indlela yokuhlola usebenzisa i-multimeter. Ungawahlola futhi uwabeke uphawu ukuze uwasebenzise esikhathini esizayo.

• Isetshenziswa Kanjani I-Cen-Tech Digital Multimeter ukuze Uhlole I-Voltage
• Ungakala kanjani ama-amps nge-multimeter
• Indlela yokulandelela ucingo nge-multimeter
