Multimeters hauv Automotive Kho
Test Ignition Coils
Fluke analogue/digital multimeters tuaj yeem kuaj qhov tsis kam ntawm 0.01Ω (Hom 88) txog 32MΩ. Qhov no ua rau kev sim ignition coils yog qhov tseeb thiab yooj yim heev. Cov multimeters tsis tuaj yeem ntsuas qhov ntsuas qis dua 1Ω.
Ntsuas cov coil tsis kam
Yog tias koj xav tias lub ignition coil tsis ua haujlwm zoo, koj yuav tsum xyuas qhov kev tiv thaiv ntawm lub hauv paus thiab theem nrab coils. Kev ntsuam xyuas yuav tsum tau ua nrog lub tsheb sov thiab txias thiab txhua qhov txuas yuav tsum tau sim. Lub hauv paus tsis kam ntawm lub kauj yog tsawg heev thaum qhov kev tiv thaiv theem nrab yog siab. Cov neeg tsim khoom specifications yuav tsum tau sab laj. Qhov tseem ceeb tshaj plaws yog 0 - ob peb Ω rau thawj thiab 10 KΩ lossis me ntsis ntxiv rau qhov thib ob.
Kuaj qhov hluav taws xob txuas txuas
Spark plugs uas tau siv ntau xyoo thiab qhov uas qhia tau tias muaj teeb meem ntawm qhov teeb meem yuav tsum raug kuaj xyuas. Tsis yog txhua qhov kev sib txuas muaj hnub tim lub qhov hluav taws xob tau tsim rau ntawm lawv. Thaum tshav kub kub tuaj yeem ua rau lub hauv paus pob hluav taws los lo rau lub txim taws. Yog li tshem tawm lub txim hluav taws xob tuaj yeem ua rau cov kab hluav taws xob tsis zoo hauv cov xov hlau insulated. Yog li thaum tshem nws, tig nws ob peb zaug ua ntej. Yog tias koj xav tias muaj teeb meem, koj yuav tsum sim qhov kev tiv thaiv ntawm cov hlau txuas thaum maj mam twisting thiab tig nws. Tus nqi kuj yog kwv yees li 30 kΩ ib 'meter'. Qhov loj ntawm tus nqi muaj feem xyuam rau hom hlau. Ib txhia yuav tsawg dua. Rau lub hom phiaj ntawm kev ntsuas nws yog qhov zoo tshaj plaws los ua qhov sib piv nrog cov xov hlau ntawm lwm cov hluav taws xob ntawm lub cav.
Capacitance
Lub Fluke analogue / digital multimeter kuj tseem tuaj yeem kuaj lub peev xwm ntawm lub tsheb, qhov kev hloov pauv ntawm qhov tuag helium pointer qhia lub multimeter tias nws them lub capacitor. Koj tuaj yeem pom qhov sib txawv ntawm 0 mus rau infinity, xyuas kom meej tias lub capacitance yuav tsum raug kuaj los ntawm ob qho tib si cov lus qhia thiab kuj kuaj lub capacitance hauv kub thiab txias.
Kev ntsuas qhov to ntawm cov capacitor
Kuaj qhov to ntawm lub capacitor siv lub multimeter qhov kev teeb tsa tsis kam. Qhov kev tiv thaiv yuav tsum loj hlob mus rau infinity thaum lub capacitor them. Thiab lwm yam nqi qhia tau hais tias lub capacitor yuav tsum tau hloov. Kuaj lub capacitor los ntawm disconnect nws ntawm lub tsheb Circuit Court.
Hall-Effect Position Sensors
Hall-effect sensors tau hloov ntau lub ignition point ntawm lub switchboard thiab tau siv ncaj qha mus saib xyuas txoj hauj lwm ntawm lub crankshaft thiab cams nyob rau hauv uas tsis yog-switchboard ignition systems, uas qhia lub computer thaum twg yuav tua cov coils. Lub Hall effect sensor tsim ib qhov voltage proportional rau lub zog ntawm magnetic teb hla nws. Nws tuaj yeem los ntawm cov hlau nplaum lossis hluav taws xob tam sim no.
