Kev ua haujlwm ntawm digital multimeter
Digital multimeter, tseem hu ua digital multimeter (Digital Multimeter, DMM luv luv), digital multimeter lossis digital multiplexer, muaj qhov zoo ntawm daim ntawv thov dav, yooj yim txav tau yooj yim, nyeem yooj yim thiab tus nqi qis.
Yi thiab lwm yam zoo. Nws lub luag haujlwm tseem ceeb yog ntsuas qhov voltage, tam sim no thiab tsis kam nyob rau hauv hluav taws xob circuits. Peb qhov ntau no yog peb qhov tseem ceeb tshaj plaws thiab tsis tseem ceeb hauv cov khoom siv hluav taws xob. Txawm hais tias lub voj voog ua haujlwm ib txwm tuaj yeem cuam tshuam los ntawm qhov tseem ceeb ntawm qhov voltage, tam sim no thiab tsis kam. [2] Yog li ntawd, nyob rau hauv lub
Hauv kev saib xyuas huab cua, qhov ntsuas hluav taws xob, tam sim no thiab qhov tsis kam ntawm qee cov ntsiab lus tseem ceeb hauv Circuit Court yog ntsuas los ntawm digital multimeter, thiab muab piv nrog tus nqi siv thaum lub Circuit Court ua haujlwm ib txwm, qhov chaw txhaum lossis cov khoom siv hluav taws xob puas tuaj yeem txiav txim siab.
Ntxiv nrog rau kev ntsuas AC thiab DC voltage, AC thiab DC tam sim no, thiab tsis kam, cov multimeter digital kuj tuaj yeem ntsuas lub zog ntawm lub diode, qhov loj ntawm triode, capacitance, zaus, txuas ntxiv, kub, mem tes dav, lub voj voog ua haujlwm, Tus nqi txheeb ze, dBV, conductance inductance thiab qee qhov tsis zoo ntawm cov khoom siv hluav taws xob, thiab lwm yam, qee qhov multimeters kuj muaj lub cim xeeb ua haujlwm. Nrog rau kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, cov lej tso saib ntawm digital multimeters kuj nce ntxiv.
