Digital multimeter rau kev ntsuas zaus ntawm UPS fais fab mov txoj kev
Rau UPS fais fab mov. Lub stability ntawm nws cov zis voltage yog ib qho tseem ceeb parameter, cov zis zaus kuj tseem ceeb heev. Tab sis tsis ncaj qha nrog ib tug digital multimeter zaus block los ntsuas, vim hais tias nws zaus block tuaj yeem tiv taus qhov voltage tsawg heev. Tsuas yog ob peb volts. Qhov no tuaj yeem txuas nrog cov zis ntawm UPS fais fab mov 220V / 6V lossis 220V / 4V kauj ruam-down transformer, qhov hluav taws xob raug txo qis, tsis hloov qhov zaus ntawm lub hwj huam mov, thiab tom qab ntawd cov zaus thaiv thiab cov zis ntawm lub transformer txuas nrog. rau qhov zaus tuaj yeem ntsuas tawm ntawm UPS fais fab mov.
Feem ntau, kev siv digital multimeter los yog siv txoj kev ua haujlwm kom raug, tsis tuaj yeem nkag siab lub hauv paus ntsiab lus thiab kev ua haujlwm rau kev siv tsis pom kev, tsim nyog raws li txoj kev ua haujlwm kom raug kuj ua rau cov digital multimeter zoo dua rau peb siv, kom ntev lub neej ntawm qhov ntsuas.
Zaus yog tus lej ntawm lub voj voog ib lub teeb liab ua tiav ib ob. Qee qhov digital multimeter tuaj yeem ntsuas tau, xws li FT215 digital multimeter los ntawm kev suav cov naj npawb ntawm lub sijhawm ib ob qhov ntsuas lub teeb liab thiab ua rau theem kev sib tshuam los ntsuas qhov zaus ntawm lub teeb liab. Cov theem pib rau txhua qhov sib txawv yog tib yam li qib COM davhlau ya nyob twg. Nyob rau hauv AC ntsuas muaj nuj nqi, nias SHIFT pib thiab kaw qhov zaus ntsuas muaj nuj nqi. Kev ntsuas zaus siv rau AC nkaus xwb. Thaum lub sij hawm ntsuas zaus, lub analogue pointer zaub thiab ntau yam zaub qhia txog tam sim no AC voltage lossis tam sim no. Siv phau ntawv ua haujlwm ntau ntxiv los xaiv qhov qis dua rau kev nyeem ntawv ruaj khov.
Kev ceev faj rau kev ntsuas ntsuas qhov tseeb
(1) Khaws koj ob lub qhov muag perpendicular rau tus pointer thaum nyeem ntawv.
(2) Muab lub multimeter horizontally thiab kho cov neeg kho tshuab xoom ua ntej ntsuas.
(3) Thaum ntsuas qhov tsis kam, txhua zaus koj hloov qhov thaiv, koj yuav tsum kho qhov xoom. Hloov lub roj teeb nrog ib qho tshiab thaum nws tsis xoom; (4) Thaum ntsuas RC circuits, hloov lub roj teeb nrog ib qho tshiab.
(4) Thaum ntsuas qhov kev tiv thaiv hauv RC Circuit Court, txiav tawm lub zog hluav taws xob hauv Circuit Court thiab ntws lub capacitor cov hluav taws xob khaws cia ua ntej ntsuas. Tom qab tshem tawm tib neeg yuam kev hauv kev nyeem ntawv, peb txheeb xyuas lwm yam yuam kev; (5) Thaum ntsuas qhov tsis kam lossis siab voltage, peb yuav tsum hloov lub roj teeb.
(5) Kev ntsuas kev tiv thaiv lossis qhov hluav taws xob siab, koj tsis tuaj yeem tuav cov hlau ntawm tus cwj mem nrog koj txhais tes, yog li tsis txhob shunt tib neeg lub cev tsis kam, nce qhov kev ntsuas yuam kev lossis hluav taws xob poob siab.
