Kev txuas ntxiv kev tshuaj ntsuam xyuas

Kev txuas ntxiv yog lub xub ntiag ntawm ib txoj kev ua tiav rau tam sim no ntws. Ib lub voj voog ua tiav thaum nws hloov pauv. Thaum kuaj rau kev txuas ntxiv , a multimeter beeps raws li qhov kev tiv thaiv ntawm cov khoom raug kuaj. Qhov kev tawm tsam no yog txiav txim siab los ntawm qhov kev teeb tsa ntau ntawm cov multimeter

Tom qab ntawd, dab tsi yog lub cim ntawm kev txuas ntxiv hauv multimeter?

Kev txuas ntxiv : Feem ntau denoted los ntawm nthwv dej los yog diode cim . Qhov no tsuas yog sim seb puas yog lub voj voog ua tiav los ntawm kev xa ib qho me me ntawm tam sim no los ntawm Circuit Court thiab pom tias nws ua rau nws tawm mus rau lwm qhov kawg. Yog tias tsis yog, ces muaj ib yam dab tsi nyob hauv Circuit Court uas ua rau muaj teeb meem-nrhiav nws!

Ib yam li ntawd, dab tsi yog qhov teeb tsa txuas ntxiv ntawm multimeter? Tig lub dial rau Kev txuas ntxiv Test hom (). Nws yuav zoo li qhia qhov chaw ntawm lub xov tooj nrog ib lossis ntau lub zog, feem ntau tsis kam (Ω). Nrog cov kev ntsuam xyuas kev sib cais, cov multimeters zaub yuav qhia OL thiab Ω. Cov digital multimeter (DMM) beeps yog hais tias ib tug ua tiav txoj kev ( kev txuas ntxiv ) kuaj pom.

Tsis tas li ntawd, qhov kev ntsuam xyuas txuas ntxiv txiav txim siab li cas?

Hauv electronics, a continuity test yog qhov Kev tshuaj 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 ib qho hluav taws xob me me (wired nyob rau hauv series nrog ib qho LED lossis lub suab nrov tsim tawm xws li tus hais lus piezoelectric) hla txoj kev xaiv.

Dab tsi yog cov cim ntawm multimeter?

Yog hais tias koj yuav tsum ntsuas alternating tam sim no nyob rau hauv ib tug Circuit Court, txawv multimeters muaj qhov sib txawv cim ntsuas nws (thiab qhov sib thooj voltage), feem ntau yog "ACA" thiab "ACV," lossis "A" thiab "V" nrog ib kab squiggly (~) nyob ib sab los yog siab dua lawv.
