Yuav Ua Li Cas Ntsuas Hluav Taws Xob Hluav Taws Xob nrog Multimeter

  1. Kev txuas ntxiv kuaj ntsuas yog tias hluav taws xob tuaj yeem ntws los ntawm ib feem. Plug ob lub probes rau hauv multimeter thiab teem lub dial rau 'continuity.
  2. Kev tiv thaiv kuaj Tam sim no poob npaum li cas thaum hluav taws xob ntws los ntawm a tiv thaiv los yog Circuit Court.
  3. Qhov thib peb hom xeem yog rau voltage, los yog lub zog ntawm hluav taws xob siab.

Ntawm no, kuv yuav ua li cas thiaj paub yog tias kuv lub cuab yeej faulty?

Kev ntsuas qhov tsis kam nyob rau hauv xya kauj ruam yooj yim

  1. Tua tawm thiab tshem tawm koj lub cuab yeej.
  2. Tshem tawm qhov ua yuam kev ntawm koj lub cuab yeej.
  3. Tig koj lub multimeter thiab teeb tsa rau qhov chaw qis tshaj plaws.
  4. Kuaj koj lub multimeter ua haujlwm los ntawm nias lub sojntsuam ua ke.

Tsis tas li, koj ua li cas kuaj PCB tivthaiv? Txuas thiab tig lub hwj chim rau koj lub rooj tsav xwm hauv Circuit Court dua thiab ntsuas qhov voltages ntawm cov inputs thiab outputs ntawm txhua qhov cov khoom ntawm lub rooj tsavxwm. Siv koj lub voltmeter (saib Cov Lus Qhia) rau kuaj voltage theem ntawm tag nrho cov cov khoom 'input thiab output pins.

Cov lus nug tseem yog, Kuv yuav ua li cas thiaj paub yog tias kuv lub multimeter puas lawm?

Teeb koj multimeter nyeem cov kev tawm tsam thiab kov cov kev sojntsuam kuaj ua ke. Nws yuav tsum nyeem xoom ohms. Yog koj muaj qhov ntsuas tsis kam ntawm ntau dua ib ohm lossis kev nyeem ntawv tsis raug, koj yuav tsum tuaj yeem kho qhov teeb meem los ntawm kev hloov cov kev sojntsuam coj.

Qhov kev ntsuam xyuas txuas ntxiv qhia li cas txog ib feem?

Hauv electronics, a continuity test yog qhov Kev kuaj xyuas ntawm ib qho hluav taws xob Circuit Court kom pom tias tam sim no ntws (qhov tseeb tias nws yog qhov ua tiav Circuit Court). A kev ntsuam xyuas txuas ntxiv yog ua los ntawm kev tso me me voltage (wired nyob rau hauv series nrog LED los yog suab nrov tsim tiv thaiv xws li tus hais lus piezoelectric) hla txoj kev xaiv.
