Kev Ntsuam Xyuas Qhov Ntsuas ntawm Voltage ntsuas ntawm cov digital multimeter thiab pointer multimeter
Yog tias lub ntsuas hluav taws xob ntsuas yog lub zog ua lag luam, uas yog, 50 hli hloov tshiab, thiab ob leeg meters yog muaj peev xwm qhia tau tias qhov hluav taws xob ntsuas tau ntau dhau. Ntawm tib zaus, qhov tseem ceeb tshaj plaws uas cuam tshuam rau cov ntsuas ntsuas hluav taws xob ua tau ntawm cov taw kev sib txawv, uas tsis yog kev txiav txim ntawm qhov ntau. Thaum sab hauv kev tawm tsam ntawm cov ntsuas hluav taws xob yog me me, qhov sib txawv tsis pom tseeb ntawm cov ntsuas hluav taws xob yog qhov ntsuas tau ntau dua.
Hauv qhov no, nws yog tau hais tias cov ntsuas ntsuas tsis yog qhov ntsuas hlau tiag tiag tom qab cov khoom siv hluav taws xob dhau los ntawm cov khoom siv hluav taws xob, lossis cov tshuaj tiv thaiv hluav taws xob.
Tsis suav nrog cov kev ua tau saum toj saud tuaj yeem qhia tau tias ib qho ntawm ob lub moos tawm tsis yog qhov tseeb thiab xav tau txij nkawm thiab kev kho tau.
Muaj qhov yuam kev hauv kev ntsuas qhov hluav taws xob. Ua ntej tshaj plaws, koj yuav tsum nrhiav pom dab tsi yog zaus ntawm qhov ntsuas tau ntsuas AC Voltage? Qhov no puas yog voltage ib qho sine yoj ntshiab?
Tam sim no txhua yam ntau ntawm cov multimeters ntawm kev ua lag luam yog cim nrog lawv cov lus teb ntau zaus thiab ua rau cov ntsuas hluav taws xob. Rau txhua hom ntawm cov kev ua kom zoo nkauj digital, cov ntsiab lus teb yog feem ntau {} hz, thiab sine dej yog qhov yuav tsum tau (distortion tsawg dua lossis sib npaug rau 1%). Qhov ntsuas pom AC Voltage ntau tshaj li qhov tseem ceeb saum toj no tsis tuaj yeem lav qhov ntsuas qhov tseeb. Qhov no yog vim AC / DC (hloov tshiab / ncaj qha rau cov khoom siv hluav taws xob ntau dua, nws tseem muaj feem xyuam rau kev ua haujlwm ntau dua, nws tseem muaj feem xyuam rau kev ua haujlwm ntau dua,
Raws li rau lub taw qhia dav dav 0. Qhov uas tau tsim los ntawm cov neeg Asmeskas, yog li cov ntsuas hluav taws xob sib txawv ntawm cov neeg siv hluav taws xob tau yooj yim, thiab cov ntsuas hluav taws xob ntau heev, thiab pheej yig motively tsis tau muab piv nrog cov digital motimeter. Qhov hluav taws xob diam ntawm cov ntsuas hluav taws xob no feem ntau tsis raug them nyiaj los ntawm capitalitance.
Qhov sib txawv ntawm ob metres hauv kev ntsuas tib qho hluav taws xob yog ob peb lub kaum tawm ntawm cov hluav taws xob voltance, yog ib qho ntawm kev tiv thaiv tsis sib xws? Yog tias nws yog txhua qhov qub, koj puas tuaj yeem pom tias tus pointer ntawm tus taw kev sib xyaw ua ke tuaj yeem taw tes rau xoom? Rau digital motimeter, koj puas tuaj yeem pom yog tias calibration potentiometer ntawm nws AC voltage block yog xoob?
Los ntawm txoj kev, yog tias koj xav kom raug kev ntsuas AC Volfage ntawm ib qho hluav taws xob, nws raug pom zoo kom yuav ib qho kev sib tw ntawm Wave Altimeter, uas yuav muaj ib qho tseeb yoj, thiab tsis muaj dab tsi ua rau cov distortion.
