Siv tus multimeter ntau ntawm kev ntsuas deistors, Capacitors, dodes, thiab transistors
1. Qhov txhaum ntawm resistor (R) yog tias qhov txiaj ntsig tiag tiag tsis phim cov nominal tsis kam nqi. Yog li ntawd, ib qho multimimeter Ohm tuaj yeem siv los ntsuas qhov zoo ntawm lub resistor. Feem ntau, qhov txhaum ntawm ib qho resistor yog qhov qhib Circuital (ntsuas los ntawm palculation tsis muaj nqi), thiab qhov kev txhaum ntawm ib qho kev tiv thaiv luv luv circuital yog tsis tshua muaj nqi.
2. Qhov kev ua txhaum cai ntawm capacitors (c) puas tuaj yeem ua txhaum ntawm lub capacitor, thiab qhib Cais tawm ntawm lub capacitor, thiab qhib lub peev xwm ntawm lub peev xwm) thiab tsis muaj peev xwm (lub peev xwm ntawm lub peev xwm tsawg dua li ib txwm).
Kev ntsuas ntawm capacitor takeage thiab rhuav tshem: teeb tsa ntau txoj hauj lwm electing rau qhov chaw nyob rau hauv cov kev taw qhia electrolytic capacitors), thiab tom qab ntawd rov qab mus rau qhov chaw r yog infinite. Tom qab tus pointer ruaj ruaj, cov nqi tiv thaiv tau hais tias yog lub capacitor, rau cov kev sojntsuam electroly (rau cov kev sojntsuam electroly (colforolytic captions yuav tsum txuas nrog lub chaw zoo ntawm cov khoom siv hluav taws xob electrolytic).
Kev sim ua kom pom tau hais tias cov rwb thaiv tsev tsis kam ntawm electrolytic capacitors feem ntau yuav tsum tau ntau pua kilooths lossis ntau dua, thaum lub kaum ntawm megaohms lossis ntau dua. Yog tias cov rwb thaiv tsev tsis kam tsawg dua li tus nqi saum toj no, nws qhia tau tias qhov xau ntawm lub capacitor tsis haum rau kev siv. Lub rwb thaiv tsev me yuav tsum, qhov kev ua kom hnyav dua. Yog tias cov rwb thaiv tsev tsis kam yog xoom, nws qhia tau tias lub capacitor tau tawg tag lawm.
3. Cov yam ntxwv tseem ceeb ntawm Diode (d) yog nws unidirectional conductivity. Ib tug mottimeter yuav ntsuas txog qee yam tsis kam lees tus nqi nyob rau hauv ntej kev taw qhia thiab infinity nyob rau hauv rov qab taw qhia. Yog tias tus nqi tiv thaiv yog ntsuas hauv cov kev taw qhia rov qab, nws qhia tau tias Diode tau raug puas lawm.
4. Tus transistor (q) muaj ob lub junctions, thiab raws li unidirectional conductivity ntawm pn kev sib tshuam, lub hauv paus tuaj yeem muab tau yooj yim. Teeb lub multimeter rau * 1k Ohm ntau yam, thiab tom qab ntawd xav tias ib tus lej PIN ntawm transistor yog lub hauv paus. Txuas cov kev sojntsuam dub ntawm cov multomalimeter thiab txuas cov kev sojntsuam liab rau lwm tus ob pins sib cais. Yog tias cov txiaj ntsig tsis kam ntsuas ob zaug yog cov kev tawm tsam me me), thiab cov kev tawm tsam liab tau txuas nrog tus lej, thiab cov kev xav tau dub, thiab qhov kev xav tau yog qhov tseeb, thiab tus PIN yog lub hauv paus. Qhov kev puas tsuaj rau lub transistor yog feem ntau yog vim qhib lossis luv voj voog, thiab cov qauv no tau txiav txim siab seb puas muaj qhov chaw tshwj xeeb raug puas tsuaj.
