Momwe mungayang'anire fuse ndi multimeter

18.02.2023 /

Pansipa ndikuphunzitsani momwe mungayesere fusesi ndi multimeter. Muyeneranso kuyang'ana mkati mwa fusesiyo kuti mufike pansi pa zinthu ndikuwona ngati ikuwombedwa. Ndikuphunzitsani momwe mungachitire zonsezi pansipa.

Njira zofunika zomwe tidutsamo:

  • Chifukwa cha mphamvu ya fuse.
  • Om muyeso
  • Kuwona ma fuse mu bokosi la fuse
  • Fuse wowomberedwa kukana muyeso
  • Kuyang'ana momwe ma circuit alili

Ngati mumawerenga pakati pa 0 - 5 ohms (ohms), fusesi ndi yabwino. Mtengo uliwonse wapamwamba umatanthauza fuse yoipa kapena yolakwika. ngati muwerenga OL (kupitirira malire) amatanthauza fuse wowombedwa.

Momwe mungayang'anire ndi multimeter ngati fuseyi ikuwombedwa?

Pankhaniyi, kufufuza ngati fuse wowomberedwa ndi kuyesa kwa maso mwina sizingakhale zokwanira. Chifukwa chake, muyenera kugwiritsa ntchito multimeter kuti muchotse kukayikira konse.

Kubetcha kwanu bwino ndikuyesa magetsi ndikuwunika chomwe chalakwika ndi fuseyo.

  1. Choyamba, muyenera kukhala ndi njira yopititsira patsogolo pa multimeter yanu. Ma multimeter abwino kwambiri tsopano ali ndi njira iyi yogwiritsira ntchito. Kenako imodzi mwa ma probe iyenera kuyikidwa kumapeto kwa fuseyo. Zachidziwikire, kafukufuku wina wa ma multimeter anu ayeneranso kuyikidwa mbali ina ya fuse yomweyi.
  2. Apa cholinga chachikulu ndicho kudziwa ngati fuseyo ili yabwino. Chifukwa chake, mumayendedwe opitilira, multimeter iyenera kuyimba kuti iwonetse kupitiliza.
  3. Ngati mungayang'ane kupitiliza, fuyusiyo siwombedwa. Mwanjira ina, izi zikutanthauza kuti palibe kulumikizana komwe kwawonongeka kapena kugwetsedwa.
  4. M'malo mwake, zikhoza kuchitika kuti multimeter imasonyeza kukana kwakukulu popanda phokoso. Choncho, izi zikachitika, chifukwa chachikulu ndi chakuti fuseyi yawombera kale ndipo ilibe ntchito.
  5. Mutha kugwiritsanso ntchito multimeter ohmmeter ngati ilibe njira yopitilira. Chifukwa chake, muyenera kusankha ohmmeter ndikuyika mawonekedwe aliwonse kumapeto kwa fuseyo.
  6. Ngati fusesiyo ilibe, kuwerenga kwa ohmmeter kuyenera kukhala kochepa. Mosiyana ndi zimenezo, kuwerengera kudzakhala kwakukulu kwambiri ngati fusesi yawonongeka kapena kuwombedwa. (Fuseyi ndi yabwino ngati kuwerenga kwake kuli pakati pa 0 ndi 5 ohms (Ω).. Mtengo uliwonse wapamwamba umatanthauza fuse yoipa kapena yolakwika. Ngati kuwerenga kwanu ndi OL (Over the Limit), kutanthauza fuse yowombedwa.)

Momwe mungayang'anire ngati fusesi ndi yoyipa?

Apa ndipamene kuyang'ana thanzi la fuseyi kudzakuthandizani kupewa zinthu zambiri zosayembekezereka. Komabe, fuseji yabwino sichipezeka nthawi zonse, kotero muyenera kuphunzira momwe mungayang'anire momwe fuseyo ilili. Mutha kugwiritsa ntchito multimeter kapena mutha kudziwa nthawi yomweyo ngati fuseyi yawomberedwa kwathunthu.

Kupeza fuse wowombedwa sikovuta kwambiri. Nthawi zina cholumikizira chachikulu cha fuse chimasungunuka kapena kusweka.

Ngati simungathe kutsimikizira izi, mutha kupitiliza kugwiritsa ntchito multimeter. Nthawi zambiri, fusesi yowombedwa ikakhala ndi cholumikizira chosweka, palibe chotsalira koma kukonza. Mosiyana ndi izi, fusesi ili bwino ngati cholumikizira chamkati sichisungunuka. Cholumikizira ichi chiyenera kukhala bwino kuchokera kumbali imodzi ya fuse kupita kwina.

Mwachiwonekere zingakhale bwino mutakhala ndi fusesi yatsopano kuti mulowe m'malo mwawophulitsidwa. Inde, pali ma fuse ambiri omwe amapezeka pamsika. Kotero inunso muyenera kuonetsetsa kuti fuse yatsopanoyo ndi yofanana ndi yakale.

Momwe mungayang'anire fuse ndi kutumizirana ma multimeter?

  1. Kuti muyese fuse ndi multimeter, muyenera kugwiritsa ntchito njira yopitilira pa multimeter.
  2. Zingakhale bwino ngati mutagwirizanitsa ma multimeter amatsogolera kumapeto kwa fusesi. Ngati mungathe kudziwa kupitiriza pa multimeter, fuseji ndi yabwino. Kumbali ina, ndi fuse wowombedwa pokhapokha mutapeza kupitiliza mu multimeter yanu.
  3. Kumbali inayi, mutha kuyang'ana ngati coil relay ili bwino kapena ayi. Zingakhale bwino mutakhala ndi multimeter ya digito yokhala ndi ntchito zisanu ndi ziwiri za izi.
  4. Pankhaniyi, m'pofunika kugwiritsa ntchito njira yotsutsa pakati pa mtengo uliwonse wa relay. Apa kuwerenga kuyenera kukhala zero mumtengo wofananira wa onse olumikizana nawo. (1)
  5. Panthawi imodzimodziyo, okhudzana nawo m'derali ayeneranso kuwerengedwa ngati kuwerenga kosawerengeka ngati muyika ma probe pamtengo woyenerera. Ndiye mukhoza kupitiriza mutatha kuyatsa cholandilira. Mudzamva kudina pomwe kulandilako kwalimbikitsidwa.
  6. Kenako muyenera kubwereza ndondomekoyi ndi multimeter. Apa, kukana kwa kutsegulira ndi kutseka kolumikizana kuyenera kukhala kokwanira. Mutha kuyesanso ma relay olimba ndi ma multimeter. (2)
  7. Pankhaniyi, muyenera kukhala ndi kuwerenga kwa diode kuti muyese mtundu uwu wa relay. Multimeter idzawonetsa mphamvu yomwe imagwiritsidwa ntchito pa relay. Kauntala iwonetsa ziro kapena OL pomwe cholumikizira sichikugwira ntchito.
  8. Mosiyana ndi zimenezi, relay mumkhalidwe wabwino ayenera kupereka zotsatira za 0.5 kapena 0.7, malingana ndi mtundu wa relay.
  9. Mapaipi amtundu wokhazikika amakhala otsika mtengo komanso osavuta kukonza.

Tili ndi zolemba zina za HOW-TO zomwe mungayang'ane ndikuyika chizindikiro kuti mudzazigwiritse ntchito mtsogolo. Nawa ena mwa iwo: "Momwe mungasinthire amplifier ndi multimeter" ndi "Momwe mungagwiritsire ntchito ma multimeter kuti muwone kuchuluka kwa mawaya amoyo." Tikukhulupirira kuti phunziroli likuthandizani.
