Yuav ua li cas ib tug multimeter ntes oxygen sensor tsis ua hauj lwm
Rau cov txheej txheem ntawm kev siv ib tug multimeter los xyuas qhov txhaum ntawm cov pa sensor, siv lub cav ceev khiav ntawm 2500r / min rau txog 90s, thiab siv lub multimeter los ntsuas qhov voltage ntawm lub teeb liab tso zis davhlau ya nyob twg ntawm cov pa sensor. Cia peb saib ntawm tus nqi ib txwm muaj ntawm qhov voltage no.
Yuav ua li cas txheeb xyuas qhov txhaum ntawm oxygen sensor nrog multimeter
Ua kom cov pa oxygen sensor ua haujlwm, uas yog, ua rau m ntawm qhov kub siab tshaj 4oor.
Siv lub cav ceev kom khiav ntawm 2500r / min rau li 90s, thiab siv lub tshuab multimeter los ntsuas qhov voltage ntawm lub teeb liab tso zis davhlau ya nyob twg ntawm cov pa sensor. Tus nqi qub ntawm qhov voltage yuav tsum yog:
1. Thaum lub cav tso pa roj nplua nuj, cov zis hluav taws xob ntawm cov pa oxygen sensor yog 0.9/1V.
2. Thaum lub cav tso pa roj yog lean, cov zis voltage ntawm cov pa sensor yog 0/0.IV.
3. Thaum ua haujlwm kub ntawm cov pa oxygen sensor qis dua 360 degree, cov pa oxygen sensor nyob hauv lub xeev qhib thiab tsis muaj teeb liab tawm.
