Cov lus qhia daws teeb meem rau Digital Multimeters
Hais txog kev daws teeb meem thiab teeb meem kev txawj ntse ntawm digital multimeters, koj yuav tsum xub saib qhov ua txhaum ntawm sab nraud thiab tom qab ntawd sab hauv, yooj yim ua ntej thiab tom qab ntawd nyuaj, tawg rau hauv qhov chaw, thiab tsom mus rau kev sib tsoo, nrog rau kev hnov lus, txoj kev ntsuas hluav taws xob, luv luv Circuit Court. thiab qhib Circuit Court txoj kev, thiab lwm yam, kho kev txawj ntse rau digital multimeters sib koom.
1. Txoj kev xav
Siv koj lub siab los txiav txim ncaj qha rau qhov ua txhaum. Los ntawm kev tshuaj xyuas qhov muag, koj tuaj yeem pom cov khoom xws li cov xov hlau tawg, desoldering, luv Circuit Court, tawg fuse hlab, hlawv cov khoom, kev puas tsuaj, tshem tawm thiab tawg tooj liab ntawv ci ntawm cov ntawv luam tawm, thiab lwm yam .; Koj tuaj yeem kov qhov kub ntawm cov roj teeb, resistors , transistors, thiab integrated blocks, thiab xa mus rau daim duab qhia Circuit Court kom paub qhov ua rau ntawm qhov kub thiab txias.
Tsis tas li ntawd, koj tseem tuaj yeem siv koj txhais tes los xyuas seb cov khoom puas yog xoob, seb cov pins sib xyaw ua ke tau ruaj khov, thiab seb qhov hloov pauv puas tau daig; koj tuaj yeem hnov thiab hnov txog seb puas muaj cov suab txawv txawv thiab tsw tsw.
2. Txoj kev ntsuas hluav taws xob
Kev ntsuas seb qhov ua haujlwm voltage ntawm txhua qhov tseem ceeb yog qhov qub tuaj yeem pab koj sai sai nrhiav qhov txhaum. Xws li ntsuas qhov ua haujlwm voltage thiab siv voltage ntawm A / D converter.
3. Txoj kev luv luv
Txoj kev luv luv Circuit Court feem ntau yog siv rau hauv txoj kev tshawb xyuas A / D converters hais saum toj no. Txoj kev no feem ntau siv thaum kho cov twj tsis muaj zog tam sim no thiab microelectric.
4.Circuit breaking method
Tshem tawm qhov tsis txaus ntseeg los ntawm tag nrho lub tshuab lossis lub tshuab hluav taws xob. Yog hais tias qhov txhaum ploj mus, nws txhais tau hais tias qhov txhaum nyob rau hauv lub disconnected Circuit Court. Txoj kev no yog qhov tsim nyog rau cov xwm txheej uas muaj luv luv hauv Circuit Court.
5.Kev ntsuas cov khoom siv
Thaum qhov kev ua txhaum tau nqaim mus rau ib qho chaw lossis ob peb yam, nws tuaj yeem ntsuas hauv online lossis offline. Yog tias tsim nyog, hloov nws nrog cov khoom zoo. Yog tias qhov txhaum ploj mus, nws txhais tau hais tias cov khoom tsis zoo.
6.Txoj kev cuam tshuam
Tib neeg lub cev induced voltage yog siv los ua lub teeb liab cuam tshuam los soj ntsuam cov kev hloov hauv cov kua siv lead ua kua. Nws feem ntau yog siv los xyuas seb qhov input Circuit Court thiab cov khoom siv puas zoo lawm.
Cov lus qhia kho digital multimeter
Rau cov cuab yeej faulty, koj yuav tsum xub xyuas thiab txiav txim siab seb qhov kev ua txhaum tshwm sim puas muaj tshwm sim (tag nrho cov haujlwm tsis tuaj yeem ntsuas) lossis tus kheej (tus kheej lub luag haujlwm lossis tus kheej ntau yam), thiab tom qab ntawd sib txawv qhov xwm txheej thiab daws nws raws li.
1. Yog tias txhua lub zog tsis ua haujlwm, tsom mus xyuas lub zog hluav taws xob thiab A / D converter circuit.
Thaum kuaj xyuas cov khoom siv hluav taws xob, koj tuaj yeem tshem tawm cov roj teeb laminated, nias lub hwj huam hloov, txuas qhov kev ntsuam xyuas zoo ua rau lub zog tsis zoo ntawm lub ntsuas hluav taws xob nyob rau hauv kev sim, thiab txuas cov kev xeem tsis zoo ua rau lub zog zoo (rau cov khoom siv digital. multimeter). Tig qhov hloov mus rau qhov ntsuas diode. Yog tias nws pom tias yog qhov hluav taws xob tom ntej ntawm lub diode, nws txhais tau hais tias cov khoom siv hluav taws xob zoo. Yog tias qhov sib txawv loj, nws txhais tau hais tias muaj teeb meem nrog cov khoom siv hluav taws xob.
Yog tias muaj qhov qhib Circuit Court, tsom mus rau kev kuaj xyuas lub hwj chim hloov thiab cov roj teeb coj.
Yog hais tias ib tug luv luv Circuit Court tshwm sim, koj yuav tsum tau siv lub Circuit Court breaking txoj kev maj mam disconnect lub Cheebtsam uas siv lub hwj chim, tsom mus rau kev soj ntsuam lub lag luam amplifier, timer, A / D converter, thiab lwm yam. Yog hais tias ib tug luv luv Circuit Court tshwm sim, feem ntau muaj ntau tshaj ib tug integrated tivthaiv. yuav puas.
