Kev kho qhov yuam kev ntawm multimeter AC voltage cov ntaub ntawv
Lub hauv paus ntsiab lus ntawm kev ntsuas qhov hluav taws xob yog tib yam li qhov ntsuas qhov ntsuas hluav taws xob DC, ob qho tib si siv lub hauv paus ntsiab lus ntawm kev faib hluav taws xob, qhia tias muaj ntau qhov kev hloov kho dua li DC voltage ntsuas Circuit Court. Yog tias AC voltage tsis ua haujlwm, feem ntau ntawm cov rectifier diodes puas lawm. Daim ntawv thov xaiv lub diode hloov nrog kev ua haujlwm zoo ib yam li qub diode. Yog hais tias qhov zoo thiab qhov tsis zoo kuj tus nqi ntawm cov xaiv rectifier diode txawv heev los ntawm cov thawj raj, nws yuav cuam tshuam qhov tseeb ntawm AC voltage tus nqi ntawm lub multimeter.
Yog li, yuav ua li cas peb thiaj paub txog tus nqi pem hauv ntej thiab thim rov qab ntawm qhov hluav taws kub-tawm rectifier diode? qhov no yog qhov yooj yim heev. Feem ntau hais lus, AC rectifier Circuit Court ntawm lub multimeter yog tag nrho tus choj uas muaj plaub lub rectifier diodes. Thaum tus choj tag nrho ua tsis tiav, feem ntau tsuas yog ib lossis ob lub diodes rectifier raug hlawv, tsis yog tag nrho plaub. Ntev npaum li qhov ntsuas qhov ntsuas ntawm qhov tsis muaj kev puas tsuaj rau pem hauv ntej thiab thim rov qab, qhov tseem ceeb rau pem hauv ntej thiab rov qab ua haujlwm ntawm cov hluav taws kub-tawm rectifier diodes kuj paub.
