Digital multimeters muaj siab rhiab heev thiab raug thiab siv nyob rau hauv yuav luag tag nrho cov lag luam. Txawm li cas los xij, vim muaj ntau yam hauv nws qhov tsis ua haujlwm, thiab qhov randomness ntawm cov teeb meem tau ntsib yog loj, tsis muaj ntau txoj cai ua raws. Txhawm rau nrhiav qhov yuam kev, koj yuav tsum xub saib sab nraud thiab tom qab ntawd sab hauv, ua ntej yooj yim thiab tom qab ntawd nyuaj.
kev xav
Los ntawm kev nkag siab ncaj qha rau kev txiav txim siab qhov ua rau tsis ua haujlwm, los ntawm kev tshuaj xyuas qhov muag, nws tuaj yeem pom xws li kev sib txuas, desoldering, luv luv Circuit Court, tawg fuse tube, hlawv tawm cov khoom, kev puas tsuaj, thiab tooj liab ntawv ci ntawm cov ntawv luam tawm. yog lifted thiab tawg, thiab lwm yam.; Qhov kub nce ntawm cov roj teeb, cov resistors, transistors, thiab kev sib xyaw ua ke tuaj yeem kov tau, thiab qhov ua rau qhov kub tsis zoo tuaj yeem pom los ntawm kev xa mus rau daim duab kos duab. Tsis tas li ntawd, koj tuaj yeem tshawb xyuas los ntawm txhais tes seb cov khoom puas yog xoob, seb cov pins sib xyaw ua ke tau ruaj khov, thiab seb qhov hloov pauv hloov yog cassette; koj tuaj yeem hnov thiab hnov txog seb puas muaj lub suab txawv txav lossis tsis hnov tsw.
kev ntsuas voltage
Ntsuas seb qhov ua haujlwm voltage ntawm txhua lub ntsiab lus tseem ceeb yog qhov qub, thiab qhov yuam kev tuaj yeem pom sai sai. Xws li ntsuas qhov ua haujlwm voltage ntawm A / D converter, siv voltage, thiab lwm yam.
luv luv txoj kev
Txoj kev luv-circuit feem ntau yog siv rau hauv txoj kev tshawb xyuas A / D converter uas tau hais los saum toj no, thiab txoj kev no yog siv ntau dua thaum kho cov twj tsis muaj zog thiab micro-hluav taws xob.
Circuit Court breaker
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 feem ntau yog tsim rau luv luv Circuit Court.
ntsuas qhov txheej txheem
Thaum qhov 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 nrog cov khoom zoo. Yog tias qhov txhaum ploj mus, cov khoom tawg.
