Maitiro ekutarisa kutendeseka ne multimeter

Ndichishanda muindasitiri iyi, ndakadzidza kuti multimeter yakakosha. Imwe yeanonyanya kushandiswa emultimeter ndeyekuyedza kuenderera mberi. Kana iwe wanga usingazive, bvunzo yekuenderera mberi yakakosha sezvo ichitarisa kuona kana waya kana loop paPCB yatyoka.

Chero mugadziri wemagetsi weDYIR'er anofanirwa kudzidza kuita bvunzo yekuenderera mberi ine multimeter inogona kushandiswa kuyedza zvikamu zvemagetsi uye masekete munzira miriyoni dzakasiyana. Tevedza mirairo kuti udzidze kutarisa kuenderera nemultimeter.

Multimeter kugadzirisa

Fambisa iyo multimeter dial kune yekuenderera bvunzo basa kuti ushandise iyo multimeter yekuenderera mberi bvunzo basa. Iwe unofanirwa kunzwa beep yakajeka apo iyo multimeter kit inotungamira kubata. Usati waedza, zvinyoronyoro bata mazano kune mumwe nemumwe uye teerera kune beep. Iwe unofanirwa kuita izvi kuti uve nechokwadi chekuti multimeter yekuenderera kwekutarisa basa iri kushanda nemazvo.

Continuity check

Muedzo wekuenderera mberi unoona kana zvinhu zviviri zvakabatana nemagetsi: kana zvakadaro, chaji yemagetsi inogona kuyerera yakasununguka kubva kune imwe magumo kuenda kune imwe. (1)

Pane kuputika pane imwe nzvimbo muwaya kana pasina kuenderera mberi. Izvi zvinogona kunge zvakakonzerwa nefiyuzi yakakanganisika, kushomeka kwakashata, kana wiring isiriyo yedunhu.

Zvino, kuti uedze zvakanaka kuenderera mberi, ita zvinotevera:

1. Kutanga ita shuwa kuti hapana simba rinomhanya nepadunhu kana mudziyo waunoda kuyedza. Bvisa mabhatiri ese, dzima uye woabvisa kubva kumadziro.
2. Batanidza iyo nhema inotungamira kune multimeter's COM port. Uye iwe unofanirwa kuisa iyo tsvuku probe muVΩmA port.
3. Seta iyo multimeter kuyera kuenderera uye kuibatidza. Inowanzoita senge icon wave wave.
4. Iwe unofanirwa kuisa probe imwe kumagumo edunhu kana mudziyo waunoda kuyedza kuenderera mberi.
5. Womirira maresults.

Kunzwisisa Kuenderera mberi Muedzo Mhinduro

Iyo multimeter inopinza diki ikozvino kuburikidza neimwe probe uye inotarisa kana imwe probe irikuigamuchira.

Izvo hazvina basa kuti ndeipi probe inobata nzvimbo nekuti chiyero chekuenderera hachisi chekutungamira, zvisinei pane zvimwe zvinosiya, semuenzaniso kana dunhu rako riine diode. Diode yakafanana nevhavha yemagetsi yenzira imwe chete pakuti inoratidza kuenderera mberi mune imwe nzira asi kwete mune imwe.

Simba rekuyedza rinopfuura kana ma probes akabatana mune inoenderera dunhu kana yakanangana kune mumwe nemumwe. Iyo multimeter beeps uye chiratidziro chinoratidza zero (kana pedyo ne zero). Izvi zvinoreva kuti pane pfungwa yekuenderera mberi.

Iko hakuna kuenderera mberi kana simba rekuedza rikasaonekwa. Chiratidziro chinofanira kuratidza 1 kana OL (yakavhurika loop).

Cherechedza. Imwe yekuenderera mberi modhi haiwanikwe pane ese mamultimeter. Nekudaro, iwe uchiri kukwanisa kuita yekuenderera bvunzo kana yako multimeter isina chaiyo yekuenderera bvunzo modhi.

Pane kudaro, unogona kushandisa resistance mode. Izvi zvinowanzoratidzwa nechiratidzo Ohm (Ohm). Usakanganwa kuisa chiso chewachi kune yakaderera.

Voltage test

Paunenge uchiongorora mashandiro emagetsi nemagetsi maseketi, kana kuedza kufunga kuti sei dunhu risiri kushanda nemazvo, unofanirwa kuchengeta track yemhando dzakasiyana dzemagetsi. 

1. Batanidza iyo nhema inotungamira kune multimeter's COM port. Isa iyo dzvuku probe muVΩmA port.
2. Seta iyo multimeter dial kune inogara voltage mode (inoratidzwa neV ine mutsara wakatwasuka kana ⎓ chiratidzo).
3. Iyo yakanaka terminal inofanirwa kubata neiyo dzvuku probe, nepo iyo isina kunaka terminal inofanirwa kubata neiyo nhema probe.
4. Zvadaro mirira mugumisiro.

Kunzwisisa Voltage Test Results

Kunyangwe akawanda mamultimeters asina auto renji, iwe uchafanirwa kusarudza nemaoko renji yakakodzera kune voltage iri kuyerwa.

Iyo yakanyanya voltage yainogona kuyera yakanyorwa kune yega chinzvimbo pane dial. Shandisa iyo 20 volt level, semuenzaniso, kana iwe uchida kuyera zvinopfuura 2 volts asi isingasviki makumi maviri.

Kana usina chokwadi, sarudza kukosha kwepamusoro. Nekudaro, haugone kuwana fungidziro chaiyo kana huwandu hwako hwakaiswa zvakanyanya. Kune rimwe divi, iyo multimeter inongoratidza 1 kana OL kana iwe ukaisa huwandu hwakanyanya kuderera, izvo zvinoreva kuti yakawandisa kana kubva kunze. Izvi hazvikuvadze iyo multimeter, asi isu tinofanirwa kuwedzera huwandu pane dial.

Kupenengura maprobes hakuzokukuvadze; izvi zvinongoguma nekuverenga kwakashata.

Resistance test

Kuyerera kwesimba rinoshandiswa kudunhu rinoshandiswa kuverenga kushorwa. Kana ikozvino ichiyerera kudunhu pasi pekuyedzwa, voltage (resistance) inogadzirwa. Unogona kuishandisa kuona kuti dunhu kana chikamu chiri kuita zvakanaka sei. Iyo yakaderera ikozvino, yakanyanya kunaka kupikisa, uye zvinopesana.

Ramba uchifunga kuti iwe uchange uchiedza kupikisa kwedunhu rose. Kana iwe uchida kuyedza chikamu chimwe chete, senge chinopikisa, ita izvozvo pasina soldering.

Verenga pandinokuudza maitiro ekuita bvunzo yekupikisa ine multimeter:

1. Ita shuwa kuti simba harisi kupfuura nedunhu kana chikamu chaunoda kuyedza kutanga. Tora chero mabhatiri, adzime uye asunungure kubva kumadziro.
2. Batanidza iyo nhema inotungamira kune multimeter's COM port. Isa iyo dzvuku probe muVΩmA port.
3. Isa iyo multimeter kune inopikisa basa uye ibatidze.
4. Imwe probe inofanirwa kusungirirwa kumagumo edunhu kana chikamu chaunoda kuyedza.

Kunzwisisa Resistance Test Results

Resistance is non-directional; saka, hazvina basa kuti ndeipi probe inoenda kupi.

Iyo multimeter inongoverenga 1 kana OL kana iwe ukaiisa kune yakaderera renji, zvinoreva kuti yakaremerwa kana kunze kwehuwandu. Izvi hazvizokanganisa iyo multimeter, asi isu tichafanirwa kuwedzera huwandu pane dial.

Imwe mukana ndeyekuti network kana mudziyo wauri kuyedza hauna kuenderera, zvinoreva kuti ine kusingaperi kuramba. Kubatana kwepakati kunogara kuchiratidza 1 kana OL kana uchitarisa kuramba.

Chengetedzo

Kuyera kuenderera kuri nyore, asi usarege kureruka ikoko kuchikanganisa kuchengeteka kwako. Kuti uzvidzivirire kubva pakuvhunduka uye kudzivirira iyo multimeter kubva mukukuvadzwa, tevera iyi nhungamiro:

• Gara uchipfeka magirovhosi ekudzivirira akanaka kana uchishandisa multimeter.
• Gara uchidzima chiridzwa paunenge uchiyera kuenderera.
• Kana kutarisa kuenderera kuri chiitiko chenguva dzose kwauri, ita shuwa kuti unoshandura mabhatiri ako e-multimeter nguva dzose. Ruzha rwunorira runoderedza simba rebhatiri nekukurumidza. (2)

Iwe unogona kuwana mamwe multimeter bvunzo madhairekitori mune runyorwa pazasi;

• Maitiro ekuyera amps ne multimeter
• Nzira yekuwana sei dunhu diki rine multimeter
• Maitiro ekuyera DC voltage ine multimeter
