Hom multimeter - digital lossis analog - zoo dua rau cov neeg siv hluav taws xob?
Multimeter yog ib qho ntawm cov cuab yeej siv hluav taws xob uas nquag siv. Muaj ob hom multimeters nyob rau hauv kev ua lag luam: pointer multimeters thiab digital multimeters. Qhov twg ntawm ob qhov no yog qhov zoo dua rau cov kws kho hluav taws xob? Qee tus hais kom siv tus lej, qee tus hais tias siv tus taw tes. Cia peb tham txog qhov teeb meem no:
1. Txhua txoj kev tso saib muaj nws tus kheej lub zog:
Dab tsi yog cov tshuaj tiv thaiv ntawm ntau tus neeg thaum lawv pom ib qho digital multimeter? Koj yuav twv yuav raug hu, wow, qhov no multimeter zoo npaum li cas, nws tuaj yeem tso ncaj qha rau hauv cov lej tom qab ntsuas, thiab kuv tsis tas yuav nyeem nws, yooj yim npaum li cas! Zoo, cov kab lus no tau hnov los ntawm ib tug hluav taws xob uas nyiam siv analog multimeter, thiab nws retorted. Qhov kom zoo dua ntawm lub pointer lub rooj yog tias nws lub pointer viav vias, uas muaj peev xwm heev intuitively qhia cov khoom hloov pauv ntawm cov khoom ntsuas, uas yog yooj yim dua li lub rooj digital.
Los ntawm cov ntsiab lus saum toj no, nws tuaj yeem hais tau tias lawv yog qhov sib txawv. Txawm li cas los xij, cov watches digital kuj muaj qhov tseem ceeb dua, uas yog, lawv feem ntau tuaj yeem ua compact thiab portable, uas yog me ntsis zoo dua li pointer watches. Raws li qhov teeb meem backlight, kuv xav tias muaj qee qhov zoo dua pointer watches, yog li ntawd tsis suav.
2. Cov qauv siv yog txawv:
Feem ntau hais lus, txhua tus subconsciously xav tias digital multimeters yog cov cuab yeej tsim nyog rau kev ntsuas qhov ntsuas ntsuas qhov ntsuas. Piv nrog rau pointer multimeters, qhov tseeb ntawm cov multimeters yog qhov intuitive thiab ntau dua rau kev siv xws li me me overload. Lub pointer multimeter yog tsim los ntsuas cov overloads loj (qhov no muaj ib yam dab tsi ua nrog lub hauv paus ntsiab lus ua haujlwm ntawm tus taw tes). Yog li nws nyob ntawm qhov xwm txheej ntawm tus kws kho hluav taws xob ua haujlwm thiab cov khoom siv ntsuas ntau yam ntawm multimeter yog dab tsi. Raws li qhov teeb meem ntawm kev tiv thaiv kom poob, kuv tus kheej xav tias cov saib digital zoo dua me ntsis. Tom qab tag nrho, lub viav vias pointer yog lub cev meej thiab hloov tau yooj yim.
