Yakaputika multimeter fuse (gwaro, nei uye sei kugadzirisa)
Zviri mukati
Iyo DMM yakanaka chaizvo iri nyore kushandisa mudziyo. Nekudaro, kana usiri nyanzvi yemagetsi kana zvemagetsi mainjiniya, zvinhu zvinogona kushata, izvo zvakajairika. Hapana chikonzero chekuzvirova zvakanyanya. Izvi ndizvo zvinoitika nguva dzose. Chimwe chezvinhu zvinogona kukanganisa nedhijitari yako kana analog multimeter ndeye fuse inoputika.
Muchidimbu, kana iwe ukayera ikozvino zvisizvo kana yako multimeter yakaiswa kune amplifier modhi, inogona kuridza fuse yako. Iyo fuse inogona zvakare kuvhuvhuta kana iwe ukayera voltage nepo multimeter ichiri kusetwa kuyera ikozvino.
Saka kana iwe uchifungidzira kuti uri kubata nefuse inoputika uye usingazive zvekuita zvinotevera, hauzowana nzvimbo iri nani kupfuura pano. Pano tichataura pamusoro pezvinhu zvose zvine chokuita nefuse inoputika ne multimeter.
Zvinhu zvekutanga kutanga; Nei fuse yeDMM ichiridzwa?
Iyo fuse paDMM chinhu chekuchengetedza chinodzivirira kukuvadzwa kwemamita kana magetsi akawandisa. Fuse inogona kuvhuvhuta nekuda kwezvikonzero zvakawanda.
Iyo multimeter ine zviteshi zviviri zvewaya dzakanaka. Imwe chiteshi inoyera voltage uye imwe inoyera ikozvino. Chiteshi chekuyeresa magetsi chine kukwirira kwakanyanya nepo chiteshi chekuyera chiripo chine kushomeka kwakaderera. Nokudaro, kana iwe ukaisa pini kuti iite semagetsi, inenge iine kupikisa kwakanyanya. Mumamiriro ezvinhu akadaro, fuse yako yemultimeter haiputi, kunyangwe ukaiisa kuyera ikozvino. Izvi zvinodaro nekuti simba racho riri kupera nekuda kwekupikiswa kwakanyanya. (1)
Zvisinei, kana iwe ukaisa mapini kune basa razvino, rinogona kugadzira zvinopesana, izvo zvichaita kuti fuse ivhuvhute. Nekuda kweizvi, iwe unofanirwa kungwarira pakuyera ikozvino. Parallel yazvino kuyerwa muzviitiko zvakanyanyisa kunogona kutungamira kumhepo inoputika fuse nekuti ammeter ine inenge zero kuramba.
Chiyero chisina kujeka chemazuva ano hachisi icho chega chichaita kuti fuse ivhuvhute. Izvi zvinogonawo kuitika kana iwe ukamisa multimeter kuyera ikozvino uye edza kuyera voltage. Mumamiriro ezvinhu akadaro, kupikisa kwakaderera, zvichibvumira ikozvino kuyerera munzira ye multimeter yako.
Muchidimbu, kana iwe ukayera ikozvino zvisizvo kana yako multimeter yakaiswa kune amplifier modhi, inogona kuridza fuse yako. Iyo fuse inogona zvakare kuvhuvhuta kana iwe ukayera voltage nepo multimeter ichiri kusetwa kuyera ikozvino.
Ruzivo rwekutanga nezve digital multimeters
Iyo DMM ine zvikamu zvitatu: zviteshi, kuratidza, uye kusarudza knob. Iwe unoshandisa knob yekusarudza kuseta iyo DMM kune dzakasiyana siyana kuramba, ikozvino, uye voltage kuverenga. Mazhinji ma brand eDMM ane backlit anoratidza kuti avandudze kuverenga, kunyanya mumamiriro akaderera.
Kune madoko maviri kumberi kwechigadzirwa.
- COM inzvimbo yakajairika inobatanidza pasi kana kuti minus yedunhu. Chiteshi cheCOM chakasviba.
- 10A - Ichi chiteshi chinoshandiswa pakuyera mafungu akakwira.
- mAVΩ ndiyo chiteshi chinobatanidzwa newaya dzvuku. Iyi ndiyo chiteshi yaunofanira kushandisa kuyera ikozvino, voltage, uye kuramba.
Zvino zvaunoziva zvinoenda kupi zvine chekuita nemultimeter ports, unoziva sei kana uri kubata nefuridziro yemultimeter fuse?
Kuonekwa kwefuse yakavhuvhuta
Blown fuse idambudziko rakajairika nemultimeters emhando dzese. Pamusoro pekukuvara kwemidziyo, fuse inoputika inogona kukonzera kukuvara. Mumamiriro ezvinhu akadaro, nhanho yako yekuziva ichasarudza kuchengeteka kwako uye kuti unofambira mberi sei. Mazhinji mabhureki emultimeter uye zvishandiso zvine hukama zvinouya neakanakisa kuchengetedza maficha. Zvisinei, zvinoshuviwa zvikuru kunzwisisa ganhuriro dzavo uye kuziva nzira yokudzivisa nayo ngozi dzinogona kuitika.
Muedzo wekuenderera mberi unouya zvakanaka kana iwe uchida kuyedza fuse kuti uone kana yakavhuvhuta. Muedzo wekuenderera mberi unoratidza kana zvinhu zviviri zvakabatana nemagetsi. Magetsi anoyerera akasununguka kubva kune imwe kuenda kune imwe kana paine kuenderera. Kushaikwa kwekuenderera mberi kunoreva kuti pane kuzorora pane imwe nzvimbo mucheni. Unogona kunge wakatarisa fuse yemultimeter inoputika.
Iyo fuse yemultimeter yangu yaputika - chii chinotevera?
Kana yakatsva, inofanira kutsiviwa. Usanetseke; ichi chinhu chaunogona kuita iwe pachako. Zvakanyanya kukosha kutsiva fiyuzi yakapeperetswa nefuse inopihwa nemugadziri weDMM yako.
Tevedzera matanho aya kutsiva fuse paDMM;
- Tora mini screwdriver uye tanga kusunungura screws pane multimeter. Bvisa bhatiri ndiro pamwe chete nebhatiri.
- Unoona masiruuru maviri kuseri kweplate yebhatiri? Dzima.
- Zvishoma nezvishoma simudza mberi kwe multimeter.
- Kune zvikorekedzo pamucheto wezasi we faceplate ye multimeter. Shandisa simba shoma kune chiso che multimeter; tsvedzerera parutivi kuti usunungure zvikorekedzo.
- Iwe wakabudirira kuvharira zvikorekedzo kana iwe uchikwanisa kubvisa nyore kumberi kweDMM. Wave kutarisa mukati meDMM yako.
- Nyatsosimudza fuse yemultimeter yakaputika uye ita kuti ibude.
- Tsiva fiyuzi yakapeperetswa neiyo chaiyo. Semuenzaniso, kana iyo multimeter's 200mA fuse yakafuridzwa, inotsiva inofanira kunge iri 200mA.
- Ndizvo zvose. Ikozvino unganidzazve iyo DMM uye tarisa fuse iri kushanda uchishandisa yekuenderera bvunzo kuona kuti zvese zvakanaka.
Kuve neruzivo rwakakwana rwekushandisa multimeter kwakakosha kudzivirira fuse dzinoputika. Teerera pese paunoshandisa multimeter kuti usaite zvikanganiso zvinogona kukupinza mudambudziko.
Summing up
Kuti uite izvi, une ruzivo rwekutanga nezve zviteshi zve multimeter (uye kushandiswa kwavo). Iwe zvakare unoziva kuti nei fuse yako yemultimeter ichigona kuvhuvhuta uye maitiro ekuzvidzivirira. Sezvawaona, muedzo wekuenderera mberi unogona kukubatsira kuti uedze fuse kuti uone kana yakaputika. Chekupedzisira, iwe wakadzidza kutsiva yakavhuvhuta multimeter fuse - chimwe chinhu chiri nyore. Chinofanira kunge chiri chinhu chinogona kuitika mune ramangwana uye tinovimba unonzwa uine chivimbo nezvazvo mushure mekuverenga chinyorwa ichi. (2)
Tarisa zvimwe zvezvinyorwa zvedu pazasi.
- Maitiro ekushandisa Cen-Tech Digital Multimeter kutarisa Voltage
- Maitiro ekuyera amps ne multimeter
- Maitiro ekuyera DC voltage ine multimeter
