Kev siv Multimeters hauv Kev Kho Tsheb Tsheb
Test ignition kauj
Fluke analog/digital multimeter tuaj yeem kuaj qhov ua haujlwm ntawm 0.01 Ω (Hom 88) txog 32M Ω. Qhov no ua rau kev sim lub ignition coil yog qhov tseeb thiab yooj yim heev. Lub multimeter dav dav tsis tuaj yeem ntsuas qhov ntsuas qis dua 1 Ω.
Ntsuas qhov kev tiv thaiv sab hauv ntawm lub kauj
Yog tias koj xav tias lub ignition coil yog qhov txawv txav, koj yuav tsum xyuas qhov kev tiv thaiv ntawm lub hauv paus thiab theem nrab coils. Kev ntsuas yuav tsum tau ua nyias nyias thaum lub tsheb kub thiab txias, thiab txhua qhov sib koom ua ke yuav tsum tau sim. Lub hauv paus tsis kam ntawm lub kauj yog me me thaum qhov kev tiv thaiv theem nrab yog loj. Cov cim tshwj xeeb los ntawm cov chaw tsim khoom yuav tsum tau sab laj. Tus nqi kev paub yog 0-ob peb ohms rau thawj zaug thiab 10K ohms lossis ntau dua rau theem nrab.
Kuaj qhov txuas ntawm lub txim taws
Tshawb xyuas lub txim hluav taws xob uas tau siv ntau xyoo thiab thaum muaj cov cim qhia tias lawv yuav muaj teeb meem. Tsis yog txhua qhov txuas xov hlau muaj hnub tsim tawm ntawm lub txim hluav taws xob. Vim muaj cua sov siab, lub txim hluav taws xob hauv paus thiab lub qhov hluav taws xob tuaj yeem ua raws. Yog li tshem tawm lub txim hluav taws xob tuaj yeem ua rau cov hlau tsis huv thiab nkig nyob rau hauv cov hlau insulated. Yog li thaum disassembling, nws yog ib qho tsim nyog yuav tsum tig nws rov ua dua ob peb zaug ua ntej. Yog tias muaj kev xav tias muaj teeb meem, qhov kev tiv thaiv yuav tsum tau sim thaum maj mam twisting thiab tig cov hlau. Tus nqi kuj yog kwv yees li 30k Ω ib 'meter'. Tus lej muaj feem cuam tshuam nrog hom kab. Ib txhia yuav tsawg dua. Txhawm rau ntsuas qhov tseeb * thiab sib piv nrog cov xaim ntawm lwm cov ntsaws ntsaws rau hauv lub cav.
capacitance
Fluke analog/digital multimeter kuj tseem tuaj yeem ntsuas lub peev xwm ntawm lub tsheb, thiab qhov kev hloov pauv ntawm lub ntsuas hluav taws xob helium qhia tau hais tias lub multimeter tau them lub capacitor. Koj tuaj yeem pom tias qhov kev hloov pauv ntawm 0 mus rau infinity. Thov paub meej tias lub capacitance yuav tsum raug kuaj los ntawm ob qho tib si cov lus qhia, thiab tseem xyuas cov capacitance nyob rau hauv kub thiab txias.
Kuaj qhov to ntawm capacitor
Siv cov kev tiv thaiv ntau yam ntawm multimeter los ntsuas qhov to ntawm cov capacitors. Thaum lub capacitor raug them, qhov kev tiv thaiv yuav tsum nce mus rau infinity. Thiab lwm yam nqi qhia tau hais tias lub capacitor yuav tsum tau hloov. Txhawm rau kuaj lub capacitor, txiav nws los ntawm lub tsheb Circuit Court rau kev sim.
Hall Effect Position Sensor
Lub Hall effect sensor tau hloov ntau lub ntsiab lus ntawm qhov hluav taws xob ntawm lub vaj huam sib luag faib thiab yog siv los xyuas ncaj qha rau txoj hauj lwm ntawm lub crankshaft thiab cam nyob rau hauv lub vaj huam sib luag uas tsis yog hluav taws xob hluav taws xob. Nws qhia lub computer thaum twg yuav ignite lub kauj. Hall effect sensor generates ib qhov voltage uas yog proportional rau lub zog ntawm lub magnetic teb hla nws. Nws tuaj yeem los ntawm cov hlau nplaum lossis hluav taws xob tam sim no.
Test Hall Effect Sensors
Ua ntej, xyuas qhov voltage ntawm lub roj teeb. Vim tias Hall effect sensors xav tau lub zog hluav taws xob thaum solenoid li qub tsis ua. Thaum kuaj lub sensor, ua ntej txuas lub +12V hlau los ntawm lub roj teeb mus rau lub hwj chim davhlau ya nyob twg, thiab siv ib tug multimeter los ntsuas qhov voltage tawm ntawm lub teeb liab mus rau hauv av davhlau ya nyob twg. Ntxig qhov sib txawv ntawm lub sensor thiab electromagnet thiab saib seb lub analog pointer ntawm multimeter hloov. Tus nqi ntawm qhov kev hloov pauv yuav tsum nyob nruab nrab ntawm 0-12V.
Electromagnetic txoj hauj lwm sensor
Lub electromagnetic txoj hauj lwm sensor yog tsim los ntawm ib tug coil qhov txhab nyob ib ncig ntawm ib tug hlau nplaum. Cov txheej txheem ntshiab rau Pickup (hu rau) thiab Relictor (kho) yog qhov tseem ceeb. Nws cov ntsuas feem ntau yog los ntawm 0.8mm txog 1.8mm.
Ntsuas cov mem tes ntawm electromagnetic distributor
Tshem tawm lub vaj huam sib luag ntawm qhov hluav taws xob hluav taws xob, teeb lub multimeter rau DC voltage, thiab txuas mus rau lub taub hau hluav taws xob. Thaum lub cav khiav, lub mem tes yuav tshwm sim ntawm tus pointer analog. Yog tias tsis muaj mem tes, nws yuav yog vim muaj kev ua haujlwm tsis zoo hauv lub log hloov kho lossis lub tshuab hluav taws xob sib txuas. Tib txoj kev kuj tseem tuaj yeem siv los ntsuas lwm yam electromagnetic txoj hauj lwm sensors.
