Yuav ua li cas txiav txim siab xoom xaim thiab hluav taws xob xaim yog tias koj tsis nco qab nqa tus cwj mem thiab tsuas yog muaj ib lub multimeter.
Cov kev txwv ntawm cov cwj mem hluav taws xob yog qhov pom tseeb, tshwj xeeb tshaj yog cov uas muaj cov duab digital, uas tuaj yeem ua rau peb txiav txim siab yuam kev. Lub teeb muaj zog heev los nyeem vim muaj kev cuam tshuam, thiab lub teeb ci dhau los rau cov lej nyeem txawm tias lawv me dhau. Muaj ntau tus lej tso tawm, ci thiab tsaus, muaj zog thiab tsis muaj zog, yog li koj tsis tuaj yeem txiav txim siab txog qib ntawm qhov voltage. Lub suab thiab lub teeb sensor cwj mem, tsuas paub seb puas muaj hluav taws xob, tab sis tsis tuaj yeem paub tias qhov voltage yog dab tsi. Neon npuas hluav taws xob cwjmem rau kev sim sab nraum zoov, "koj tuaj yeem ua nws nyob nruab nrab ntawm hnub, sai lossis tom qab, qee yam yuav tshwm sim".
Raws li tus kws tshaj lij hluav taws xob, koj tsis tuaj yeem muaj tus cwj mem hluav taws xob, tab sis koj tsis tuaj yeem muaj multimeter. Yog vim li cas vim li cas ib tug multimeter hu ua multimeter yog vim nws muaj zog. Ib tug zoo multimeter, thaum peb overhaul thiab kho yuav ua tau ib nrab ntawm kev rau siab.
Ib tug phooj ywg nug, tsis muaj hluav taws xob cwj mem, yuav ua li cas siv lub multimeter kom paub qhov txawv ntawm xoom thiab hluav taws xob hlau? Rau cov kws hluav taws xob, qhov no yog qhov teeb meem hauv kindergarten. Nov yog qhov kuv qhia.
Ua ntej tshaj plaws, txiav txim siab seb koj qhov chaw ua haujlwm puas muaj lub ntiaj teb hlau, yog tias muaj lub ntiaj teb hlau, nws yooj yim heev rau kev khiav lag luam.
1. Thaum lub hwj huam mov yog peb-theem, tsib-xaim, peb teeb lub multimeter mus rau theem siab tshaj plaws ntawm AC voltage iav, raws li, los ntsuas qhov voltage ntawm tsib kab. Nyob nruab nrab ntawm ob kab ntawm qhov hluav taws xob ntawm 380 ob yog hluav taws kub, qhov hluav taws xob ntawm 220 hluav taws, ib txoj kab xoom, qhov hluav taws xob yog xoom lossis me me, xoom kab, hauv av.
2. fais fab rau ib-theem peb-xaim, multimeter mus rau 220V AC iav, raws li, los ntsuas qhov voltage ntawm txhua ob kab. Tsis muaj qhov hluav taws xob lossis qhov hluav taws xob tsawg heev ob kab yog xoom thiab hauv av, qhov seem yog qhov hluav taws kub.
Yog tias tsis muaj av, kom paub qhov txawv ntawm xoom thiab hluav taws xob xaim yuav ua haujlwm li cas?
Qee qhov multimeters muaj qhov cim "H" rau kev ntsuas hluav taws xob. Tsuas yog teeb lub multimeter rau qhov cim no, cia tus cwj mem dub dai saum huab cua lossis qhwv koj cov ntiv tes nyob ib puag ncig nws, thiab kov cov xaim koj xav ntsuas nrog tus cwj mem liab; qhov uas qhia txog tus nqi loj yog qhov hluav taws kub, thiab qhov uas qhia txog tus nqi me me los yog tsis muaj nqi ntawm tag nrho yog xoom xaim thiab lub ntiaj teb hlau. Yog tias koj qhwv tus cwj mem dub nyob ib ncig ntawm koj txhais tes, cov zaub yuav nkag siab dua.
