Tshawb xyuas yuav ua li cas siv lub folding digital multimeter kom pom qhov tawg ntawm cov hlau
Folding digital multimeter yog cov cuab yeej siv hluav taws xob ntau hauv kev siv hluav taws xob hluav taws xob. Ntxiv rau qhov ntsuas qhov voltage, tam sim no, tsis kam, capacitance, inductance, thiab lwm yam., folding digital multimeter kuj tuaj yeem siv tau yooj yim los nthuav nws cov haujlwm kom ua tiav cov khoom siv kom zoo tshaj plaws ntawm cov nyhuv. Peb feem ntau ntsib cov xwm txheej zoo li no hauv kev ua haujlwm hauv peb lub khw: ib lub cable twb paub tias nyob rau hauv lub xeev qhib Circuit Court, vim hais tias lub cable yog qhwv nyob rau hauv rwb thaiv tsev, nws yog ib qho nyuaj rau nrhiav tau qhov qhib Circuit Court taw tes, ces peb yuav ua li cas. siv lub folding digital multimeter kom sai thiab raug pom qhov chaw ntawm qhov tawg?
Yog tias koj tab tom nrhiav qhov tawg ntawm cov hlau zoo tib yam, txuas ib kawg ntawm cov hlau nrog qhov tawg mus rau cov hlau nyob ntawm 220V, thiab dai rau lwm qhov kawg hauv huab cua, tom qab ntawd kho lub foldable digital multimeter rau 2V AC, thiab tuav cov xim dub Lub nib ntawm tus cwj mem, thiab lwm yam tes tuav tus cwj mem liab thiab maj mam txav mus rau ntawm daim tawv nqaij rwb thaiv tsev ntawm cov kab tawg. Lub sijhawm no, kev nyeem ntawv ntawm folding digital multimeter yuav tsum yog li 0.4V. Thaum qhov kev nyeem ntawv tso tawm poob thiab me dua li qhov kev nyeem ntawv dhau los, txoj hauj lwm uas tus cwj mem liab nyob ntawm lub sijhawm no yog txoj hauj lwm nyob rau qhov chaw tawg.
Cov saum toj no yog txhawm rau nrhiav qhov chaw tawg ntawm cov hlau, yog li peb yuav ua li cas thiaj li kuaj tau qhov tawg ntawm lub cable uas tuab dua li cov hlau? Qhov tseeb, txoj kev no yooj yim heev. Yog tias peb xav txheeb xyuas cov kab hluav taws xob, peb tsuas yog yuav tsum tau quav lub taub liab ntawm cov digital multimeter Muab tshuaj txhuam ib daim kab xev ntawm aluminium foil daim kab xev, nyob rau hauv txoj kev no peb nce qhov chaw kuaj pom ntawm folding digital multimeter. Vim li cas koj thiaj yuav tsum tau paste tin foil daim kab xev? Qhov no yog vim hais tias cov rwb thaiv tsev ntawm lub cable yog thicker, yog li qhov kev ncua deb ntawm tus cwj mem thiab cov hlau tseem ceeb ntawm lub cable yuav ntev dua, yog li nws yuav tsum tau muab tshuaj txhuam tin foil daim kab xev rau ntawm tus cwj mem. Nws kuj yuav tsum qis dua qhov kev nyeem ntawv thaum ntsuas cov hlau. Kev nyeem ntawv ntawm lub ntsuas cable yog hais txog 0.32V. Thaum muaj ntau dhau lawm, txoj hauj lwm uas tus cwj mem nyob twj ywm nyob rau lub sijhawm no yog txoj hauj lwm qhov chaw nres tsheb nyob.
