Fuse ya multimeter yowombedwa (chitsogozo, chifukwa chake ndi momwe mungakonzere)
Zamkatimu
DMM ndiyosavuta kugwiritsa ntchito chida. Komabe, ngati simuli katswiri wamagetsi kapena zamagetsi, zinthu zitha kusokonekera, zomwe ndizabwinobwino. Palibe chifukwa chodzimenya nokha kwambiri. Izi ndi zomwe zimachitika nthawi zonse. Chimodzi mwazinthu zomwe zingasokonekera ndi digito kapena analogi multimeter ndi fuse yowombedwa.
Mwachidule, ngati muyesa zamakono molakwika pamene multimeter yanu yakhazikitsidwa kukhala amplifier mode, ikhoza kuwomba fuse yanu. Fuseyi imathanso kuwomba ngati muyeza voteji pomwe ma multimeter akadali okhazikitsidwa kuti ayeze pano.
Chifukwa chake ngati mukuganiza kuti mukuchita ndi fuse yowombedwa ndipo simukudziwa choti muchite, simupeza malo abwino kuposa pano. Apa tikambirana zonse zokhudzana ndi fuse zowombedwa ndi multimeter.
Zinthu zoyamba poyamba; Chifukwa chiyani fuse ya DMM imawomberedwa?
Fuse pa DMM ndi gawo lachitetezo lomwe limalepheretsa kuwonongeka kwa mita ngati magetsi akuchulukira. Fuse ikhoza kuwomba pazifukwa zingapo.
Multimeter ili ndi madoko awiri a mawaya abwino. Doko limodzi limayesa mphamvu yamagetsi ndipo linalo limayesa panopo. Doko loyezera voteji lili ndi kukana kwakukulu pomwe doko loyezera pano lili ndi kukana kochepa. Chifukwa chake, ngati muyika pini kuti igwire ntchito ngati voteji, imakhala ndi kukana kwakukulu. Zikatero, fusesi yanu ya multimeter sidzawomba, ngakhale mutayiyika kuti iyeze zomwe zikuchitika. Izi zili choncho chifukwa mphamvuyi ikutha chifukwa cha kukana kwakukulu. (1)
Komabe, ngati muyika zikhomo pazomwe zikuchitika, zitha kupanga zosiyana, zomwe zingapangitse fuseyo kuwomba. Pachifukwa ichi, muyenera kusamala poyesa madzi. Muyezo wamakono wofananira muzovuta kwambiri ukhoza kuyambitsa fusesi yowombedwa mwachangu chifukwa ammeter ili ndi kukana kwa ziro.
Muyezo wamakono wolakwika si chinthu chokhacho chomwe chingapangitse fuse kuwomba. Izi zikhoza kuchitikanso ngati mutakhazikitsa multimeter kuti muyese zamakono ndikuyesa kuyesa magetsi. Zikatero, kukana kumakhala kotsika, kulola kuti pakali pano kuyenda molunjika ku multimeter yanu.
Mwachidule, ngati muyesa zamakono molakwika pamene multimeter yanu yakhazikitsidwa kukhala amplifier mode, ikhoza kuwomba fuse yanu. Fuseyi imathanso kuwomba ngati muyeza voteji pomwe ma multimeter akadali okhazikitsidwa kuti ayeze pano.
Zambiri pazambiri zama digito multimeter
DMM ili ndi magawo atatu: madoko, mawonedwe, ndi chosankha. Mumagwiritsa ntchito mfundo yosankha kuti muyike DMM kuti isawerengedwe mosiyanasiyana, pakali pano, komanso pamagetsi. Mitundu yambiri ya ma DMM imakhala ndi zowonetsa zowunikira kuti ziwerengedwe bwino, makamaka m'malo opepuka.
Pali madoko awiri kutsogolo kwa chipangizocho.
- COM ndi doko wamba lomwe limalumikizana ndi pansi kapena kuchotsera kwa dera. Doko la COM ndi lakuda.
- 10A - Dokoli limagwiritsidwa ntchito poyesa mafunde apamwamba.
- mAVΩ ndi doko lomwe waya wofiyira amalumikizako. Ili ndiye doko lomwe muyenera kuligwiritsa ntchito kuyeza pano, ma voltage, ndi kukana.
Tsopano popeza mukudziwa zomwe zimapita ku madoko a multimeter, mumadziwa bwanji ngati mukuchita ndi fuse ya multimeter?
Kuzindikira kwa fuse
Ma fuse ophulika ndi vuto lofala ndi ma multimeter amitundu yonse. Kuphatikiza pa kuwonongeka kwa zida, ma fuse omwe amawombedwa amatha kuvulaza. Zikatero, luso lanu lidzatsimikizira kuti ndinu otetezeka komanso momwe mungapitirire patsogolo. Mitundu yambiri yama multimeter ndi zida zofananira zimabwera ndi chitetezo chochititsa chidwi. Komabe, ndikofunikira kwambiri kumvetsetsa zofooka zawo ndikudziwa momwe mungapewere zoopsa zomwe zingachitike.
Kuyesa kopitilira muyeso kumakhala kothandiza mukafuna kuyesa fusesi kuti muwone ngati ikuwombedwa. Kuyesa kopitilira kumawonetsa ngati zinthu ziwiri zilumikizidwa ndimagetsi. Mphamvu yamagetsi imayenda momasuka kuchokera kumodzi kupita ku imzake ngati pali kupitiriza. Kupanda kupitiriza kumatanthauza kuti pali kupuma kwinakwake mu unyolo. Mutha kuyang'ana fuse ya multimeter yowombedwa.
Fuse ya multimeter yanga yawomba - chotsatira chiyani?
Ngati yapsa, iyenera kusinthidwa. Osadandaula; ichi ndi chinachake chimene mungachite nokha. Ndikofunikira kwambiri kusintha fusesi yowombedwa ndi fusesi yoperekedwa ndi wopanga DMM yanu.
Tsatirani izi kuti musinthe fusesi pa DMM;
- Tengani screwdriver mini ndikuyamba kumasula zomangira pa multimeter. Chotsani mbale ya batri komanso batire.
- Mukuwona zomangira ziwiri kuseri kwa mbale ya batri? Afufute.
- Pang'onopang'ono kwezani kutsogolo kwa multimeter.
- Pali zokowera m'munsi m'mphepete mwa faceplate ya multimeter. Ikani mphamvu pang'ono pa nkhope ya multimeter; lowetsani m'mbali kuti mutulutse mbedza.
- Mwatsekereza makoko ngati mutha kuchotsa mosavuta gulu lakutsogolo la DMM. Tsopano mukuyang'ana mkati mwa DMM yanu.
- Mosamala kwezani fusesi ya multimeter yowombedwa ndikuyisiya ituluke.
- Bwezerani fusesi yowombedwa ndi yolondola. Mwachitsanzo, ngati fusesi ya 200mA ya multimeter iwomberedwa, m'malo mwake iyenera kukhala 200mA.
- Ndizomwezo. Tsopano phatikizaninso DMM ndikuwona kuti fusesi ikugwira ntchito pogwiritsa ntchito kuyesa kopitilira kuti muwonetsetse kuti zonse zili bwino.
Kukhala ndi chidziwitso chokwanira cha momwe mungagwiritsire ntchito multimeter ndikofunikira kuti mupewe ma fuse omwe amawombedwa. Samalani nthawi zonse mukamagwiritsa ntchito ma multimeter kuti mupewe zolakwika zomwe zingakugwetseni m'mavuto.
Kufotokozera mwachidule
Kuti muchite izi, muli ndi chidziwitso chofunikira pa madoko a multimeter (ndi kugwiritsa ntchito kwawo). Mumadziwanso chifukwa chake fusesi ya multimeter yanu imatha kuwomba komanso momwe mungapewere. Monga momwe mwawonera, kuyesa kopitilira kungakuthandizeni kuyesa fuse kuti muwone ngati ikuwombedwa. Pomaliza, mudaphunzira momwe mungasinthire fusesi yowombedwa ndi multimeter - chinthu chosavuta kwambiri. Iyenera kukhala chinthu chotheka mtsogolomo ndipo tikukhulupirira kuti mukumva chidaliro nacho mutawerenga nkhaniyi. (2)
Onani zina mwazolemba zathu pansipa.
- Momwe Mungagwiritsire Ntchito Cen-Tech Digital Multimeter Kuwona Voltage
- Momwe mungayesere ma amps ndi multimeter
- Momwe mungayesere magetsi a DC ndi multimeter
