Momwe mungapezere dera lalifupi ndi multimeter (6-step guide)

Kodi mwakumanapo ndi vuto la mabwalo amfupi mukamagwira ntchito ndi mabwalo amagetsi kapena zida? Pamene dera lalifupi likuwononga nthawi zonse dera lanu lamagetsi kapena bolodi, zimakhala zovuta kwambiri. Kuzindikira ndi kukonza dera lalifupi ndikofunikira.

Ngakhale pali njira zosiyanasiyana zodziwira dera lalifupi, kugwiritsa ntchito multimeter ndi imodzi mwazosavuta. Zotsatira zake, tapanga kufotokozera mwatsatanetsatane momwe tingapezere dera lalifupi ndi multimeter.

Kodi dera lalifupi ndi chiyani?

Dera lalifupi ndi chizindikiro cha waya wosweka kapena wosweka, zomwe zimapangitsa kuti magetsi asamayende bwino. Zimapangidwa pamene waya wonyamula pakali pano akhudzana ndi ndale kapena pansi pa dera.

Komanso, chikhoza kukhala chizindikiro cha dera lalifupi ngati muwona ma fuse akuwomba pafupipafupi kapena wodutsa dera akuyenda pafupipafupi. Dongosolo likayambika, mutha kumvanso phokoso lokweza.

Multimeter ndi chimodzi mwazinthu zofunikira zomwe mungagwiritse ntchito poyang'ana zazifupi mu mawaya a nyumba yanu. Ndi iyo, mutha kuyang'ana zovuta zamagetsi monga zazifupi mpaka pansi. Multimeter imatha kuyang'ana mwachidule pa bolodi lozungulira, monga pakompyuta yapakompyuta. Kuphatikiza apo, imathanso kuyang'ana mabwalo afupikitsa mu mawaya amagetsi agalimoto yanu.

Njira zopezera dera lalifupi ndi multimeter ya digito

Mwa kukonzanso dera lalifupi mwamsanga, muchepetse chiopsezo cha kuwonongeka kwa waya ndi kutsekemera komanso kuteteza wodutsa dera kuti asapse. (1)

Kuti mupeze dera lalifupi lokhala ndi multimeter, tsatirani izi:

Khwerero #1: Khalani Otetezeka Ndikukonzekera

Ndikofunikira kwambiri kuwonetsetsa kuti zonse zikuyenda bwino musanagwiritse ntchito multimeter kuti mudziwe dera lalifupi. Izi zimatsimikizira kuti dera lanu lamagetsi kapena ma multimeter anu sawonongeka mukakusaka dera lalifupi.

Musanafufuze chilichonse, onetsetsani kuti dera lanu lamagetsi lazimitsidwa. Izi zikuphatikizapo kuchotsa mabatire ndi ma adapter magetsi.

Taonani: Ngati simukuzimitsa mphamvu zonse kuderali musanayese, mutha kulandira kugwedezeka kwakukulu kwamagetsi kapena kugwedezeka kwamagetsi. Chifukwa chake, yang'anani kawiri kuti magetsi omwe ali muderali azima.

Khwerero #2 Yatsani ma multimeter anu ndikuyikhazikitsa. 

Yatsani ma multimeter mutayang'ana kawiri kuti zonse ndizotetezeka kugwiritsa ntchito. Kenako gwiritsani ntchito knob yosinthira kuti muyike kuti ikhale yoyeserera mosalekeza kapena kukana, kutengera kuthekera kwa multimeter yanu.

Langizo: Ngati ma multimeter anu ali ndi makonda ena okana, tikulimbikitsidwa kuti musankhe sikelo yotsika kwambiri.

Khwerero #3: Yang'anani ndikusintha Multimeter

Kuti muwonetsetse kuti ma multimeter anu akupatseni miyeso yonse yomwe mukufuna, muyenera kuyesa ndikuyesa musanagwiritse ntchito. Kuti muchite izi, gwirizanitsani nsonga za kafukufuku wa multimeter yanu.

Ngati ili munjira yokana, kukana kuwerengera pa multimeter yanu kuyenera kukhala 0 kapena kuyandikira zero. Ngati kuwerenga kwa ma multimeter kuli kwakukulu kuposa zero, yesani kuti ma probes awiri akakhudza, mtengowo ukhale zero. Kumbali ina, ngati ili mumayendedwe opitilira, kuwalako kudzawala kapena buzzer idzamveka ndipo kuwerenga kudzakhala 0 kapena pafupi ndi ziro.

Khwerero #4: Pezani Chigawo cha Schematic

Mukakhazikitsa ndikuwongolera ma multimeter, muyenera kupeza ndikuzindikira zigawo zomwe mudzakhala mukuyesa mabwalo amfupi.

Kukaniza kwamagetsi kwa gawoli, mwina, sikuyenera kukhala kofanana ndi zero. Mwachitsanzo, kuyika kwa amplifier yomvera mchipinda chanu chochezera pafupi ndi TV yanu kudzakhala ndi cholepheretsa mazana angapo ohm (osachepera).

Bonasi: Onetsetsani kuti chigawo chilichonse chili ndi kukana pang'ono posankha zigawozi, mwinamwake zidzakhala zovuta kuzindikira dera lalifupi.

Khwerero #5: Onani Dera

Mutatha kupeza gawo ili lomwe mudzayesere kuti likhale lalifupi, gwirizanitsani zofiira ndi zakuda za multimeter yanu kudera.

Nsonga yachitsulo ya kafukufuku wakuda iyenera kulumikizidwa ndi nthaka kapena chassis yamagetsi.

Kenaka gwirizanitsani nsonga yachitsulo ya kafukufuku wofiira ku chigawo chomwe mukuyesa kapena kudera lomwe mukuganiza kuti ndi lalifupi. Onetsetsani kuti ma probe onse alumikizana ndi chitsulo monga waya, chigawo chotsogolera, kapena zojambula za PCB.

Khwerero #6: Yang'anani mawonekedwe a multimeter

Pomaliza, tcherani khutu pakuwerenga pamawonekedwe a ma multimeter pamene mukusindikiza ma probe ofiira ndi akuda motsutsana ndi zigawo zachitsulo za dera.

• Resistance Mode - Ngati kukana kuli kochepa ndipo kuwerenga kuli ziro kapena kuyandikira zero, kuyesa kwapano kumadutsamo ndipo dera limapitilira. Komabe, ngati pali dera lalifupi, mawonedwe a multimeter adzawonetsa 1 kapena OL (otseguka dera), kusonyeza kusowa kwa kupitiriza ndi dera lalifupi mu chipangizo kapena dera lomwe likuyesedwa.
• Continuity Mode - Multimeter imawonetsa ziro kapena pafupi ndi ziro ndi ma beeps kuwonetsa kupitiliza. Komabe, palibe kupitiriza ngati multimeter ikuwerenga 1 kapena OL (lopu lotseguka) ndipo silimalira. Kupanda kupitiriza kumasonyeza dera lalifupi mu chipangizo choyesedwa.

Malangizo Ogwiritsa Ntchito DMM Kuti Mupeze Dera Lalifupi

Ma multimeter angagwiritsidwe ntchito kuyang'ana mabwalo afupikitsa ndi mawonekedwe a dera lanu chifukwa amatha kugwira ntchito ngati voltmeter, ohmmeter ndi ammeter.

Sankhani chipangizo choyenera                             

Kuti muwone maulendo afupikitsa pamagetsi, onetsetsani kuti mukugwiritsa ntchito multimeter yoyenera. Ngakhale ma multimeter onse amatha kuyeza zamakono, magetsi, ndi kukana, ma multimeter apamwamba amatha kugwira ntchito zina zosiyanasiyana. Kwa multimeter yosunthika, ikhoza kukhala ndi zowerengera zowonjezera, zomata, ndi mitundu.

Onani mawonekedwe ndi tsatanetsatane                        

Chiwonetsero chachikulu, chosankha chosankha, madoko ndi ma probe ndiye zigawo zazikulu za multimeter yanu. Komabe, ma multimeter akale a analogi adaphatikizanso kuyimba ndi singano m'malo mowonetsa digito. Pakhoza kukhala madoko anayi, theka la iwo ndi ofiira ndipo theka lina ndi lakuda. Doko lakuda ndi la COM port ndipo ena atatuwo ndi owerengera ndi kuyeza.

Dziwani madoko a chipangizo chanu

Pomwe doko lakuda limagwiritsidwa ntchito polumikizira COM, madoko ena ofiira amachita ntchito zosiyanasiyana. Madoko otsatirawa akuphatikizidwa:

• VΩ ndi gawo loyezera kukana, voteji, ndi kuyesa kupitiliza.
• µAmA ndi muyeso wa muyeso wapano mudera.
• 10A - amagwiritsidwa ntchito kuyeza mafunde kuchokera ku 200 mA ndi pamwamba.

M'munsimu muli maphunziro ena ndi malangizo mankhwala kuti mukhoza onani;

• Momwe mungayesere wowononga dera ndi multimeter
• Momwe mungadziwire waya wosalowerera ndi multimeter
• zabwino kwambiri multimeter
