Yuav ua li cas txiav txim qhov zoo ntawm quartz siv lead ua nrog digital multimeter
Siv lub tshuab digital multimeter los ntsuas quartz siv lead ua yog ceev thiab raug. Txoj kev yog raws li nram no:
Kauj Ruam 1: Teem lub digital multimeter rau 20MΩ, thiab xyuas cov quartz siv lead ua kom xau thiab luv Circuit Court raws li cov qauv siv.
Kauj ruam 2: Tig lub digital multimeter mus rau CAP: 2000pF txoj hauj lwm, ntxig rau qhov kuaj quartz siv lead ua rau hauv CX xeem qhov, thiab cov ntawv nyeem hauv qab no yuav tshwm sim:
①Yog hais tias lub thawv capacitance CO tus nqi ntawm cov quartz siv lead ua rau sab yog me dua li cov nqi ib txwm muaj (piv nrog qhov ntsuas qhov qub quartz siv lead ua, lossis piv nrog cov ntaub ntawv muab los ntawm cov chaw tsim khoom), lossis txawm tias OpF, nws txhais tau tias qhov ntsuas siv lead ua ua rau Muaj qhov qhib Circuit Court txhaum hauv tus ncej, lossis cov phaj siv lead ua tawg. Yog hais tias tus nqi sib txawv ntawm lub thawv capacitance CO yog ntsuas, nws qhia tau hais tias cov siv lead ua nyob rau hauv kev sim yog to los yog luv-circuited.
② Yog tias qhov ntsuas qhov ntsuas qhov ntsuas ntawm lub quartz siv lead ua siab tshaj "1", nws txhais tau hais tias cov khoom siv hluav taws xob ntsuas tau tawg lossis luv luv.
③ Yog tias qhov ntsuas qhov ntsuas tsis ruaj khov, nws txhais tau hais tias cov hlau lead electrode ntawm quartz siv lead ua tsis zoo los yog siv lead ua poob.
