2.1 Ntsuas qhov tsis kam sab hauv ntawm cov khoom siv
Nyob rau hauv phau ntawv ntawm Boeing lub dav hlau, qhov kev txiav txim siab tus nqi ntawm txhua qhov yuav tsum tau muab, yog li yog tias koj xav paub seb tus nqi tiv thaiv ntawm txhua yam yog qhov qub, ncaj qha txiav tawm hluav taws xob ntsaws ntawm qhov cuam tshuam thiab siv lub ohmmeter ntawm cov digital. multimeter.
Cov ntaub ntawv tuaj yeem ntsuas tus nqi tiv thaiv.
2. 2 Kab txuas ntxiv ntsuas
Txij li cov kab ntawm lub dav hlau ntev ntev, txoj hauv kev los ntsuas txoj kab ntawm txoj kab yog txiav cov khoom ntawm ob qho kawg ntawm kab, ces txuas ib kawg mus rau hauv av xaim ntawm lub dav hlau, thiab ntsuas qhov tsis kam ntawm lwm qhov. kawg rau hauv av. Txoj kev ntsuas tau ua tiav siv lub ohm ntau ntawm cov digital multimeter. Xav txog qhov muaj nyob ntawm kev tiv thaiv kev tiv thaiv, yog tias ntsuas tus nqi ruaj khov nyob rau hauv ob peb ohms, nws txhais tau hais tias cov kab tsis zoo; yog hais tias tus nqi kuj yog loj, nws txhais tau hais tias muaj ib tug qhib Circuit Court nyob rau hauv ib qho chaw. Koj tseem tuaj yeem siv "luv luv Circuit Court test function" ntawm digital multimeter los ua pov thawj tias cov kab txuas nrog thaum lub buzzer beeps.
2. 3 Component fais fab mov ntsuas
Yog tias koj xav txiav txim seb lub hwj chim ntawm cov khoom siv puas yog qhov qub, koj yuav tsum xub paub hauv phau ntawv seb lub hwj chim ntawm cov khoom yog DC lossis AC, nrog rau tus nqi ntawm cov khoom siv hluav taws xob, thiab tom qab ntawd txiav tawm. lub hwj chim ntsaws ntawm lub tivthaiv thiab kaw nws.
Kaw qhov kev hloov pauv mus txawv tebchaws, siv cov ntaub ntawv DC voltage lossis AC voltage cov ntaub ntawv sib raug rau digital multimeter los ntsuas. Hauv dav hlau, cov khoom feem ntau yog muab nrog 28V DC lossis 115V AC. Thaum ntsuas 115V AC voltage, xyuam xim rau kev nyab xeeb vim qhov hluav taws xob siab.
3 Kev xaus
Digital multimeter yog ib qho ntawm cov cuab yeej ntsuas hluav taws xob uas feem ntau siv hauv aircraft hluav taws xob thiab hluav taws xob daws teeb meem. Paub txog kev ua haujlwm, qauv, siv txoj kev thiab kev ceev faj ntawm digital multimeter, seb nws puas tuaj yeem siv rau hauv kev saib xyuas aviation
Nws yog ib qho tseem ceeb heev los txiav txim qhov txhaum qhov tseeb thiab sai. Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, digital multimeters yuav ua lub luag haujlwm ntau dua hauv kev saib xyuas aviation.
