Luv luv piav qhia txog kev ua haujlwm yooj yim ntawm kev ntsuas kev tiv thaiv nrog multimeter.
1. Ua ntej txuas cov kev xeem coj mus kuaj. Lub multimeter tuaj yeem ua tus pointer lossis digital zaub. Cov hlau kuaj liab tau muab tso rau hauv VΩ txoj hauj lwm, thiab cov hlau kuaj dub tau muab tso rau hauv COM davhlau ya nyob twg los xyuas kom meej tias lub multimeter yog qhov qub.
2. Tig lub iav multimeter. Thaum ntsuas kev tiv thaiv, siv cov iav tiv thaiv. Yog tias koj tsis paub meej txog tus nqi tiv thaiv, koj yuav tsum xub teeb tsa qhov hloov pauv mus rau qhov siab tshaj plaws, thiab tom qab ntawd hloov ntawm qhov loj mus rau qhov me me, kom lub ntsuas ntsuas ntsuas qhov ntsuas tag nrho. Tsuas yog siab dua 1/2 ntawm qhov ntsuas. Tom qab xaiv qhov tsim nyog magnification theem, kov ob qhov kev xeem coj kom tus pointer taw tes rau xoom txoj hauj lwm. Yog tias tus pointer deviates los ntawm xoom txoj hauj lwm, qhov "zero adjustment" pob qhov rooj yuav tsum tau kho kom rov qab tus pointer mus rau xoom kom ntseeg tau tias qhov ntsuas tau raug.
3. Txuas ob ntu ntawm cov resistor. Txuas cov kev xeem coj ua casually. Tsis muaj qhov zoo lossis qhov tsis zoo. Xyuas kom qhov kev sib cuag zoo.
4. Nyeem cov ntaub ntawv tso tawm los ntawm multimeter. Yog tias tsis muaj cov ntaub ntawv tshwm sim ntawm lub multimeter, nws yuav yog tias tus resistor puas lawm. Tau kawg, lwm qhov ua tau yog qhov ntau tsis txaus, yog li hloov qhov ntau.
5. Ua kom qhov ntsuas ntau. Yog tias tsis muaj cov ntaub ntawv, nws tsuas yog txhais tau tias tus resistor puas lawm. Yog tias muaj cov ntaub ntawv tso tawm cov ntaub ntawv, xyuam xim rau chav tsev ntawm lub iav.
Lub hauv paus ntsiab lus ntawm multimeter:
Lub rhiab magnetoelectric DC ammeter (microampere meter) yog siv los ua lub taub hau ntsuas. Thaum ib tug me me tam sim no hla lub 'meter', yuav muaj ib tug qhia tam sim no. Txawm li cas los xij, lub taub hau ' meter ' tsis tuaj yeem dhau qhov tam sim no loj, yog li qee qhov kev tiv thaiv yuav tsum tau txuas nrog rau kev sib txuas lossis series nrog lub taub hau 'meter' kom shunt lossis txo qhov hluav taws xob, txhawm rau ntsuas qhov tam sim no, qhov hluav taws xob thiab kev tiv thaiv hauv Circuit Court.
Kev ceev faj rau kev siv multimeter:
1. Ua ntej siv lub tshuab multimeter, koj yuav tsum ua "txhim kho xoom xoom", uas yog, thaum tsis muaj hluav taws xob ntsuas, lub ntsuas ntsuas multimeter yuav tsum taw tes ntawm xoom voltage lossis xoom txoj haujlwm tam sim no.
2. Thaum siv lub tshuab multimeter, tsis txhob kov cov hlau ntawm cov hlau lead ntawm koj txhais tes. Qhov no tuaj yeem ua kom qhov tseeb ntawm qhov ntsuas ntawm ib sab tes thiab kev nyab xeeb ntawm tus kheej ntawm qhov tod tes.
3. Thaum ntsuas qee qhov hluav taws xob, koj tsis tuaj yeem hloov lub zog thaum ntsuas, tshwj xeeb tshaj yog thaum ntsuas qhov hluav taws xob siab lossis tam sim no loj, koj yuav tsum tau them sai sai. Txwv tsis pub, lub multimeter yuav puas. Yog tias koj xav tau hloov lub zog, koj yuav tsum txiav tawm qhov kev sim ua ntej, thiab tom qab ntawd ntsuas tom qab hloov lub zog.
4. Thaum siv lub multimeter, nws yuav tsum tau muab tso rau kab rov tav kom tsis txhob ua yuam kev. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj kom tsis txhob muaj kev cuam tshuam ntawm sab nraud magnetic teb ntawm multimeter.
5. Tom qab siv lub multimeter, qhov hloov pauv yuav tsum tau teem rau qhov siab tshaj plaws AC voltage ntau. Yog tias nws tsis siv sijhawm ntev, lub roj teeb hauv lub tshuab hluav taws xob yuav tsum tau muab tshem tawm los tiv thaiv lub roj teeb los ntawm corroding lwm yam khoom hauv lub ntsuas.
