Yuav ua li cas ntsuas qhov ntsuas kub ntawm lub tshuab rhaub dej hluav taws xob nrog multimeter
Lub tshuab hluav taws xob lub tshuab hluav taws xob nrog qhov ntsuas kub ntawm qhov ntsuas kub yuav hloov nrog qhov ntsuas kub ntawm qhov ntsuas kub, yog li qhov kev tiv thaiv ntawm cov ntaub ntawv digital multimeter kuj ntsuas qhov tsis kam ntawm qhov ntsuas kub kom paub nws qhov zoo lossis qhov tsis zoo. Ntawm no peb qhia txog txoj kev ntsuas tshwj xeeb.
Kub sensor rau hluav taws xob dej rhaub.
Hluav taws xob lub rhaub dej nrog lub ntsuas kub yog feem ntau qhov ntsuas kub tsis zoo ntawm cov thermistor, kev tiv thaiv yuav txo qis nrog qhov nce hauv qhov kub thiab txias, nws tus nqi nominal ntsuas ntawm 25 degree. Qhov ntsuas kub no muaj ntau yam nominal qhov tseem ceeb, xws li feem ntau siv 10KΩ, 20KΩ, 50KΩ. ntsuas qhov ntsuas kub ntawm lub tshuab rhaub dej hluav taws xob yog qhov zoo lossis qhov tsis zoo, raws li tus nqi nominal ntawm digital multimeter yuav raug hloov kho kom haum rau cov iav uas tsim nyog, nrog cov cwj mem liab thiab dub ntawm multimeter tau nyob rau hauv kev sib cuag nrog cov hlau daim. ntawm lub plug, lub multimeter yuav tsum tau qhia kom muaj ib tug haum kuj (thiab tus nqi nominal yuav tsis yog ib tug loj sib txawv), thiab ces pinch lub hlau ib feem ntawm lub sensor. Tom qab ntawd nyem cov hlau ib feem ntawm lub sensor, nws cov nqi tiv thaiv yog tias muaj qee qhov kev hloov pauv, ces lub sensor yog qhov zoo.
Digital Multimeter.
Kev ntsuas, yog hais tias lub multimeter qhia tau hais tias tus nqi kuj me me los yog infinity, qhia tias lub sensor muaj teeb meem, nyob rau lub sij hawm no koj tuaj yeem tshawb xyuas seb lub sensor plug txoj hauj lwm raug txiav tawm los yog xaim, yog tias lub ntsaws yog zoo, ces tsuas yog hloov ntawm tib yam. specifications ntawm kub sensor.
