Yuav Siv Ib Tug Neeg Mechanical Ntau Ntau Lawm
Neeg kho tshuab roj puv, tseem hu ua qhov ntsuas sib thooj lossis taw tes multimeter, yog qhov ntxov tshaj plaws siv los kuaj cov khoom siv hluav taws xob. Nws tau muab faib ua kev tiv thaiv, tam sim no, thiab voltage ranges.
Cov theem tam sim no tau muab faib ua DC thiab AC ntau qib, thiab AC Voltage tsis zoo lossis tsis zoo. Piv txwv li, txhawm rau ntes 220V Tsev Neeg AC lub zog, koj tsuas yog xav tau teeb tsa qib mus rau 250V lossis 500v, kos tus pointer viav vias yog qhov tam sim no thiab hluav taws xob theem. 250 qib siv rau 220V yuav tsum tau teeb tsa ntawm 250 thiab 200.
Nyob rau hauv 500v ntau, xyuas 50 meter txoj haujlwm hauv qab no. Rau qhov 220V ntau, nws yuav tsum yog 2/3 ntawm 20 meter cov lus yuav tsis yog qhov tseeb, nws tuaj yeem paub tseeb tias qhov hluav taws xob yog qhov qub. Txheeb xyuas 10 tus lej hauv 1000V ntau, thiab rau qhov thib peb, qhov chaw 220V tom qab 2. Muab cov kev nyeem tsawg dua 2.
DC voltage tau muab faib ua qhov zoo thiab tsis zoo, nrog cov kev sojntsuam liab ua qhov tsis zoo thiab cov kev sojntsuam dub ua tsis zoo. Tsis txhob ua yuam kev, txwv tsis pub muaj rab koob yuav thim rov qab thiab lub ntsuas yuav raug puas yog tias muaj txoj hauv kev ntev. Thaum kuaj pom ob thiab thib peb cov transistors, qhov tsis sib xws yog qhov tseeb. Nyob rau lub sijhawm no, kev sojntsuam dub yog qhov zoo thiab daim liab liab yog qhov tsis zoo.
Cov hom tam sim no tsis siv ntau, tsuas yog txoj hlua nws mus rau hauv Circuit Court, hla nws.
Cov hom tsis kam yog siv dav, uas tseem yog vim li cas vim li cas thiaj li yog qhov tseem ceeb me ntsis rau cov neeg muaj txiaj ntsig. Txawm li cas los xij, nws yuav tsum tau siv xoom, uas yog qhov kev txhawj xeeb tshaj plaws. Ntxiv mus, nws lub durability tsis zoo li digital meters, thiab nws yog ib txwm ua txhaum thiab ntshav. Txawm li cas los xij, ntes Circuit Court thiab kev ua si hluav taws xob muaj zog dua li siv cov ntsuas digital. Thaum teev rau 10k, nws tuaj yeem daws cov teeb meem feem ntau ntawm cov teeb meem kev muaj teeb meem.
Txoj kev siv tau yog los teeb tsa qhov tsis kam mus rau qee theem, thawj xoom nws, xws li 1k theem. Muab cov pointer los ntawm 1k txhua qhov chaw nws tau muab tso rau, thiab tib yam siv rau lwm theem. Yog tias tus pointer rov qab mus rau xoom, tom qab ntawd muab nws tso rau 100 lossis 10 lub zog. Feem ntau cov pointer gauges tsis muaj gep hom, thiab xaiv hom 1st tuaj yeem txiav txim siab seb cov hlau yog los yog tawm. Nws tseem tuaj yeem tshawb xyuas cov hluav taws xob sib xyaw xws li capacitors, diodes, fais fab transistors, thiab lwm yam, uas yuav raug tshawb pom ntawm Baidu.
Ntsiab lus: Txhua yam, cov taw tes meters tsis zoo li digital meters, thiab kev puas tsuaj ntawm tus pointer meters yog siab dua. Lawv tsis haum rau cov hluav taws xob uas tawm mus kho vaj tse, tab sis rau cov neeg ua haujlwm kho cov laug cam.
