Yuav ua li cas ntsuas UPS fais fab zaus nrog digital multimeter
Rau UPS fais fab mov. Qhov kev ruaj ntseg ntawm qhov hluav taws xob ntawm nws lub davhlau ya nyob twg tso zis yog qhov tseem ceeb, thiab qhov zaus ntawm nws cov zis kuj tseem ceeb. Txawm li cas los xij, koj tsis tuaj yeem siv ncaj qha los ntawm kev thaiv cov khoom siv digital los ntsuas vim tias qhov hluav taws xob uas cov zaus thaiv tuaj yeem tiv taus tsawg heev. Tsuas yog ob peb volts xwb. Lub sijhawm no, koj tuaj yeem txuas 220V / 6V lossis 220V / 4V kauj ruam-down transformer mus rau qhov kawg ntawm UPS cov khoom siv hluav taws xob kom txo tau qhov voltage yam tsis hloov qhov zaus ntawm lub hwj huam mov. Tom qab ntawd txuas cov zaus thaiv mus rau qhov tso zis ntawm lub transformer los ntsuas UPS fais fab mov. zaus ntawm.
Feem ntau, kev siv digital multimeters yuav tsum tau ua raws li txoj kev raug. Koj siv tsis tau nws qhov muag tsis pom kev yam tsis nkag siab cov ntsiab lus thiab kev ua haujlwm. Kev ua haujlwm tsim nyog thiab raug yuav kuj yuav pab tau cov digital multimeter kom zoo dua los ntawm peb thiab txuas lub neej ntawm lub ntsuas. lub neej.
Zaus yog tus lej ntawm lub voj voog ib lub teeb liab ua tiav ib ob. Qee qhov digital multimeters tuaj yeem ntsuas, xws li FT215 digital multimeter, uas ntsuas qhov zaus ntawm lub teeb liab los ntawm kev suav cov kev sib tshuam ntawm cov teeb liab ntsuas thiab qhov ua rau theem ib thib ob. Cov theem pib ntawm txhua qhov sib txawv yog tib yam li qib COM davhlau ya nyob twg. Nyob rau hauv AC ntsuas muaj nuj nqi, nias tus yuam sij SHIFT pib thiab nres qhov zaus ntsuas kev ua haujlwm. Kev ntsuas zaus yog rau AC nkaus xwb. Thaum ntsuas zaus, qhov analog pointer zaub thiab ntau yam zaub qhia txog qhov tam sim no AC voltage lossis tam sim no. Siv phau ntawv muaj nuj nqi kom nce qib qis qis kom tau txais kev nyeem ntawv ruaj khov.
Yuav ua li cas ntsuas qhov zoo ntawm hluav taws xob dej rhaub kub sensor nrog multimeter
Kub sensor rau hluav taws xob dej rhaub.
Qhov ntsuas kub ntsuas siv hauv cov tshuab hluav taws xob hluav taws xob feem ntau yog lub thermistor nrog qhov ntsuas kub tsis zoo. Qhov kev tiv thaiv yuav txo qis thaum kub nce. Nws tus nqi nominal yog ntsuas ntawm 25 degree. Qhov ntsuas kub no muaj ntau yam ntawm nominal qhov tseem ceeb, xws li 10KΩ, 20KΩ, thiab 50KΩ. Thaum ntsuas qhov zoo ntawm lub tshuab hluav taws xob rhaub dej kub sensor, kho cov digital multimeter mus rau qhov tsim nyog tsis kam raws li nws tus nqi nominal, thiab siv cov xim liab thiab xim dub coj los ntawm cov multimeter los kov cov ntawv hlau ntawm lub ntsaws (saib daim ntawv. duab saum toj no). Nyob rau lub sijhawm no, lub multimeter yuav tsum tso saib Muaj tus nqi tsim nyog (tsis txawv ntawm tus nqi nominal), thiab tom qab ntawd tuav cov hlau ntawm lub sensor nrog koj txhais tes. Yog tias muaj qee qhov kev hloov pauv ntawm tus nqi tiv thaiv, nws txhais tau tias lub sensor yog qhov zoo.
Digital Multimeter.
Thaum lub sij hawm ntsuas, yog hais tias tus nqi kuj tshwm sim los ntawm lub multimeter yog heev me me los yog infinite, nws txhais tau tias muaj teeb meem nrog lub sensor. Nyob rau lub sijhawm no, koj tuaj yeem tshawb xyuas seb lub ntsuas hluav taws xob puas tawg lossis txuas nrog. Yog hais tias lub ntsaws yog zoo, ces tib txoj kev yog los hloov lub kub sensor nrog tib specification. .
