Dab tsi yog qhov kev ua haujlwm ntawm automotive voltage tester cwj mem uas cov neeg siv hluav taws xob yuav tsum muaj?
Ntau tus kws tshaj lij hluav taws xob tau siv los siv cov cwj mem hluav taws xob digital. Yog vim li cas?
Vim tias lwm yam cuab yeej tsis tseem ceeb npaum li tus cwj mem hluav taws xob, cov cwj mem hluav taws xob digital yog qhov yuav tsum muaj cov cuab yeej hluav taws xob, uas qhia txog qhov tseem ceeb ntawm tus cwj mem hluav taws xob.
1. Yooj yim nqa
Ib lub cuab yeej me me uas dai rau hauv koj lub hnab tsho, tsis zoo li koj nyob nraum swaggering nyob ib ncig ntawm lub rooj cob qhia nrog multimeter txhua hnub.
2. Siv tau thiab yooj yim
Txawm hais tias tus cwj mem digital tsuas muaj ob peb qhov hluav taws xob, 12 24 36 55 110 220. Hauv kev saib xyuas, tsuav yog tus nqi tsis raug ntsuas, nws feem ntau tuaj yeem paub qhov txawv ntawm AC thiab DC.
3. Tib neeg lub cev induction
Yog tias ib txoj kab tawg lawm, nws yog ib qho tsim nyog yuav tsum nrhiav qhov breakpoint kom raug thiab sai sai. Nyob rau hauv rooj plaub no, lub multimeter tsis tuaj yeem siv rau kev tso tawm siab, thiab tsis muaj txoj hauv kev yog tias tsis muaj tam sim no dhau los ntawm lub ntsuas ntsuas. Lub sensor muaj nuj nqi los ua ke. Txuas cov kab mus rau AC point (xws li 220) thiab tuav lub ntsuas qhov tseem ceeb los so lub taub hau hlau ntawm tus cwj mem rau ntawm daim tawv nqaij insulating ntawm kab. Txawm qhov twg lub teeb qhia tawm mus, lub breakpoint yuav nyob ntawd. Thaum ib txhais tes kov cov xov kawg thiab lwm txhais tes nias lub pob no, lwm qhov xov kawg yog ntsuas, thiab qhov txuas ntxiv ntawm txoj kab tuaj yeem kuaj pom. Tshwj xeeb tshaj yog thaum kuaj xyuas lub fuse.
4. On-site kab kab
Cov cwj mem digital kuj muaj qhov ua haujlwm zoo. Tus tswj transformer feem ntau inputs 380V thiab outputs 6.3V 12V 24V 36V 110 (127)V 220V. Txuas ib kab mus rau ib lub qhov tso zis tawm thiab sau 123456 uas yog rau koj, thiab ntsuas qhov hluav taws xob ntawm lwm qhov kawg kom cais 6 kab raws li cov kab khawm (feem ntau, 5 kab rau ob txoj kev tswj hwm yog txaus), thiab sau 78 luv luv. -circuiting ob kab. Nws kuj tseem tuaj yeem cais 2 kab rau teeb pom kev zoo (36V tsis txawv ntawm qhov hluav taws kub thiab xoom kab), peb kab yog luv luv-circuited thiab sau UVW, thiab tom qab ntawd peb kab tau muab faib ua cov kab hluav taws xob (theem yog thim rov qab thaum lub tshuab ntsuas yog thim rov qab), thiab thaum kawg ib kab yog grounded. Ntawm qhov kawg, xyuas cov av xaim uas muaj induction rau hauv av. Qhov ntawd yog qhov pib txaus. Yog tias koj tseem xav tau ntau txoj kab hloov mus, solenoid li qub, thiab ntau yam kev sojntsuam kab, koj tsuas yog yuav tsum tau rov ua cov qauv no ib zaug, thiab koj tuaj yeem tiv nrog ntau kab.
