Momwe Mungagwiritsire Ntchito Cen-Tech Digital Multimeter Kuwona Voltage

18.02.2023 /

Mungafunike kuyeza voteji yomwe ikudutsa dera, koma simudziwa momwe mungayambire kapena kuti. Tapanga nkhaniyi kuti ikuthandizeni kugwiritsa ntchito Cen-Tech DMM kuyesa magetsi.

Mutha kugwiritsa ntchito multimeter ya digito kuyesa magetsi ndi njira zosavuta komanso zosavuta izi.

  1. Onetsetsani chitetezo choyamba.
  2. Sinthani chosankha kukhala magetsi a AC kapena DC.
  3. Gwirizanitsani ma probe.
  4. Onani voteji.
  5. Tengani kuwerenga kwanu.

Zithunzi za DMM 

Multimeter ndi chipangizo choyezera mphamvu zingapo zamagetsi. Zinthuzi zingaphatikizepo ma voltage, resistance, ndi current. Amagwiritsidwa ntchito makamaka ndi amisiri ndi okonza akamagwira ntchito yawo.

Ma multimeter ambiri a digito ali ndi magawo angapo omwe ndi ofunikira kudziwa. Magawo ena a digito multimeters ndi awa.

  • Chithunzi cha LCD. Kuwerengera kwa multimeter kudzawonetsedwa apa. Kawirikawiri manambala angapo amawerengedwa. Ma multimeter ambiri masiku ano ali ndi chophimba chakumbuyo kuti chiwonetsedwe bwino mumdima komanso kuwala kochepa.
  • Imbani chogwirira. Apa ndipamene mumakhazikitsa multimeter kuti muyese kuchuluka kwake kapena katundu. Amagawidwa m'magawo angapo okhala ndi zosankha zosiyanasiyana. Izi zidzatengera zomwe mukuyezera.
  • Jacks. Awa ndi mabowo anayi pansi pa multimeter. Kutengera ndi zomwe mukuyezera komanso mtundu wa chizindikiro chomwe mukugwiritsa ntchito ngati gwero, mutha kuyika masensa pamalo aliwonse omwe akukuyenererani.
  • Zofufuza. Mumalumikiza mawaya awiri akuda ndi ofiira ku multimeter yanu. Awiriwa adzakuthandizani kuyeza mphamvu zamagetsi zomwe mukuchita. Amakuthandizani kulumikiza multimeter ku dera lomwe mukufuna kuyeza.

Multimeters nthawi zambiri amaikidwa m'magulu malinga ndi kuchuluka kwa zowerengera ndi manambala omwe amawonetsa pazenera. Ma multimeter ambiri amawonetsa ma 20,000.

Zowerengera zimagwiritsidwa ntchito pofotokoza momwe ma multimeter angapangire miyeso. Awa ndi akatswiri omwe amawakonda kwambiri chifukwa amatha kuyeza kusintha kwakung'ono mu dongosolo lomwe amalumikizana nalo.

Mwachitsanzo, ndi 20,000 count multimeter, munthu akhoza kuona kusintha kwa 1 mV mu chizindikiro poyesedwa. Multimeter imakondedwa pazifukwa zingapo. Zifukwa izi ndi izi:

  • Amapereka kuwerengera kolondola, kotero mutha kudalira pa iwo.
  • Iwo ndi otsika mtengo kugula.
  • Amayeza zinthu zambiri zamagetsi ndipo motero amasinthasintha.
  • Multimeter ndi yopepuka komanso yosavuta kunyamula kuchokera kumalo ena kupita kwina.
  • Multimeters amatha kuyeza zotulutsa zazikulu popanda kuwonongeka.

Multimeter Basics 

Kuti mugwiritse ntchito multimeter, choyamba muyenera kudziwa zomwe mukufuna kuyeza.

Voltage ndi muyeso wapano

Kuti muyeze voteji ya AC, tembenuzirani mfundo yosankha kukhala 750 mu gawo la AC.

Ndiye, Lumikizani chowongolera chofiyira ku socket yolembedwa VΩmA ndi chotsogolera chakuda ku socket yolembedwa COM.. Kenako mutha kuyika malekezero a ma probe awiri otsogola pazingwe za dera lomwe mudzakhala mukuyesa.

Kuti muyeze voteji ya DC mudera, gwirizanitsani kutsogolo kwakuda ndi cholowetsa cha jack cholembedwa COM, ndi kafukufuku wokhala ndi waya wofiyira ndikulowetsa kwa jack yolembedwa kuti VΩmA.. Sinthani kuyimba kwa 1000 mu gawo lamagetsi la DC. Kuti muwerenge, ikani malekezero a ma probe awiri otsogolera pamawaya a chigawocho poyesedwa.

Umu ndi momwe mungayesere magetsi ndi Cen-Tech DMM. Kuyeza komweko mu dera lokhala ndi ma multimeter, gwirizanitsani chitsogozo chofiira ku socket ya 10ADC ndi kutsogolo kwakuda ku socket ya COM., Ena, tembenuzirani mfundo yosankha kukhala 10 amps. Gwirani malekezero ma probe awiri otsogolera pazingwe za dera lomwe likuyesedwa. Jambulani zomwe zikuwerengedwa pakali pano pazenera.

Ndikofunikira kudziwa kuti ma multimeter osiyanasiyana amatha kuchita mosiyana. Chonde onani buku la wopanga kuti muwone momwe limagwirira ntchito. Izi zimapewa kuwonongeka kwa multimeter komanso kuthekera kwa kuwerenga zabodza.

Kugwiritsa ntchito Cen-Tech DMM Kuwona Voltage

Mutha kugwiritsa ntchito ma multimeter awa kuti muyeze voteji yomwe imadutsa gawo la gawo.

Mutha kuchita ndi 5 zosavuta komanso zosavuta zomwe ndifotokoza pansipa. Izi zikuphatikizapo:

  1. Chitetezo. Musanalumikize DMM kudera kuti muyesedwe, onetsetsani kuti chosankhacho chili pamalo oyenera. Izi zichepetsa mwayi wodzaza kauntala. Muyeneranso kuyang'ana mayendedwe ozungulira ndi magetsi kuti muchepetse kuvulala.

Mukhozanso kuonetsetsa kuti derali silinasokonezedwe ndi aliyense ndipo likugwira ntchito bwino.

Yang'anani ma probe awiri otsogolera ndikuwonetsetsa kuti sanawonongeke. Osagwiritsa ntchito ma multimeter okhala ndi ma probe owonongeka. M'malo mwawo poyamba.

  1. Tembenuzani konopo yosankha kuti musankhe voteji ya AC kapena DC. Kutengera mtundu wa voteji yomwe mukufuna kuyeza, muyenera kutembenuza chosankhacho kuti chikhale chomwe mukufuna.
  2. Gwirizanitsani ma probe. Pamagetsi a DC, gwirizanitsani choyesa chofiira ku cholowera cha VΩmA ndipo choyesa chakuda chimatsogolera ku jack yolowetsa wamba (COM). Kenako tembenuzirani mfundo yosankha kukhala 1000 mu gawo la DCV. Pambuyo pake, mudzatha kuyeza voteji ya DC mu dera.

Pa voteji ya AC, lumikizani choyesa chofiira ku jack yolowetsa yolembedwa kuti VΩmA ndipo kuyesa kwakuda kumatsogolera ku jakisoni wamba (COM). Chosankha chosankhidwa chiyenera kutembenuzidwa kukhala 750 ku malo a ACV.

  1. Onani voteji. Kuti muyese mphamvu yamagetsi, gwirani malekezero a ma probes awiri kuti muwone mbali zowonekera za dera lomwe likuyesedwa.

Ngati voteji yomwe ikuyesedwa ndi yotsika kwambiri pazomwe mwasankha, mutha kusintha malo osankha. Izi zimathandizira kulondola kwa ma multimeter powerenga kuwerenga. Izi zidzakuthandizani kupeza zotsatira zoyenera.

  1. Inu kutenga kuwerenga. Kuti muwerenge kuchuluka kwa voliyumu yoyezedwa, mumangowerenga zowerengera kuchokera pazenera lomwe lili pamwamba pa multimeter. Zowerenga zanu zonse zikuwonetsedwa apa.

Kwa ma multimeter ambiri, chophimba chowonetsera ndi LCD, chomwe chimapereka chiwonetsero chomveka bwino bwino komanso chosavuta kugwiritsa ntchito. (1)

Cen-Tech Digital Multimeter Features

Kuchita kwa Cen-Tech DMM sikusiyana kwambiri ndi ma multimeter wamba. Izi zikuphatikizapo:

  1. Chosankha chosankha. Mutha kugwiritsa ntchito gudumuli kuti musankhe ntchito yomwe mukufuna komanso chidwi chonse cha multimeter.
  2. Banana Probe Ports. Iwo ali pansi pa multimeter yopingasa. Amasindikizidwa kuchokera pamwamba mpaka pansi.
  • 10 ACP
  • VOmmA
  • COM
  1. Awiri a lead probes. Ma probe awa amalowetsedwa muzolowetsa za jack. Kutsogola kofiira nthawi zambiri kumatengedwa ngati kulumikizana kwabwino kwa multimeter. Kufufuza kwakuda kwakuda kumatengedwa ngati kulumikizidwa kolakwika mudera la multimeter.

Pali mitundu yosiyanasiyana ya ma probes otsogolera kutengera ma multimeter omwe mumagula. Amawaika m’magulu molingana ndi malekezero omwe ali nawo. Izi zikuphatikizapo:

  • Nthochi kwa tweezers. Ndizothandiza ngati mukufuna kuyeza zida zokwera pamwamba.
  • Thirani nthochi kwa ng'ona. Ma probes amtunduwu ndi othandiza poyesa mawaya akuluakulu. Zimakhalanso zabwino poyezera mapini pa bolodi la mkate. Ndiwothandiza chifukwa simuyenera kuwasunga pamene mukuyesa gawo linalake.
  • Banana Hook IC. Amagwira ntchito bwino ndi mabwalo ophatikizika (ICs). Izi ndichifukwa choti amamangiriridwa mosavuta ku miyendo ya mabwalo ophatikizika.
  • Nthochi kuyesa ma probe. Ndiwotsika mtengo kwambiri kuti asinthe akathyoka ndipo amapezeka mumitundu yambiri.
  1. Chitetezo cha fuse. Amateteza ma multimeter kumagetsi ochulukirapo omwe amatha kudutsamo. Izi zimapereka chitetezo chofunikira kwambiri. (2)

Kufotokozera mwachidule

Cen-Tech Digital Multimeter ndizomwe mukufunikira pakali pano kuti muyese magetsi aliwonse kapena apano. Cen-Tech Digital Multimeter imasunga nthawi ndikukuthandizani kuyeza kuthamanga kwamagetsi mwachangu. Ndikukhulupirira kuti mwapeza nkhaniyi yamomwe mungagwiritsire ntchito Cen-Tech DMM kuyesa magetsi kukhala othandiza. Nawa kalozera wabwino wowonera ma voltage a waya wamoyo.
