Cov ntawv thov ntawm tshiab -} Ntaus digital multimeters hauv kev lag luam
Digital motionimeter rau kev kuaj lub tsheb ua txhaum
Thaum daws teeb meem hluav taws xob ntawm lub tsheb, qhov tseem ceeb tshaj plaws yog cov txheej txheem ntawm inferring qhov ua rau ntawm cov malfunction. Tus txheej txheem no tseem ceeb heev. Qhov no yog vim tias koj tsis tuaj yeem pom cov xwm txheej sab hauv thiab tsis tuaj yeem rhuav tshem ntau cov khoom siv xws li txhua yam. Los ntawm kev siv cov kev xav thiab cov kauj ruam tsim nyog, teeb meem tuaj yeem pom sai. Cov cuab yeej tseem ceeb hauv cov txheej txheem no yog multimeter.
Tus multiveter yog ib qho ntawm feem ntau siv cov cuab yeej hluav taws xob kev kho hluav taws xob, siv los ntsuas voltage, tam sim no, thiab kev tawm tsam. Tab sis cov lus qhia impedance ntawm analog (pointer) puv siv thaum ntxov dhau lawm, uas muaj qhov cuam tshuam tseem ceeb ntawm Circuit Court thaum ntsuas. Hom ntsuas no feem ntau siv 9v voltage rau kev sim ua, yog li nws yog ib qho yooj yim rau kev puas tsuaj hluav taws xob Cheebtsam. Tab sis cov Rigol DM3000 Digital Motival me ntsis zam qhov xwm txheej no.
Nws cov tswv yim impedance yog siab, thiab nws qhov tseeb thiab kev ua tau zoo dua rau analog meters. Qhov voltage thaum ntsuas ntsuas kuj yog tsawg, yog li nws yuav tsis puas cov khoom sib xyaw ntawm txhua qhov ntsuas. Tab sis kuj tseem muaj teeb meem nrog cov ntxhuav cov zauv. Nws tsis tuaj yeem tso cov ntaub ntawv ntawm qhov nce lossis txo qis hauv kev ntsuas nyeem. Thaum lub sijhawm tso tawm kev sim tshuaj thiab cav tsom xam, nws yuav pom tias cov digital metres tsis tuaj yeem muab cov kev hloov pauv tau ruaj khov. DM3000 kov yeej cov shortcomings ntawm cov neeg digital meters thiab hloov lawv nrog cov pob txha caj qaum / digital ua ke meters. Nws muaj qhov zoo ntawm ob chav digital thiab analog meters rau kev ntsuas fynamic.
Saib xyuas ntawm hauv paus chaw nres tsheb Hluav Taws Xob Hluav Taws Xob
Raws li cov cuab yeej loj loj, cov chaw nres tsheb hauv paus yuav tsum soj ntsuam cov cim ntau. Saib xyuas tshwj xeeb saib lub zog hluav taws xob thiab ib puag ncig ntawm lub hauv paus chaw nres tsheb. Lub zog fais fab yog qhov xwm txheej yooj yim rau cov khoom lag luam, thiab cov chaw sib txawv ib puag ncig xws li cov av noo muaj peev xwm cuam tshuam rau cov khoom lag luam. Saib xyuas cov txiaj ntsig qhov tseem ceeb hauv cov chaw no tuaj yeem pab tiv thaiv thiab daws cov teeb meem. Lub sij hawm xyuas lub sij hawm ntev thiab qhia tseeb ntawm cov ntaub ntawv khaws tseg tuaj yeem muab cov ntawv xa ntxiv rau kev siv thiab kev loj hlob ntxiv.
Nyob rau hauv tag nrho cov chaw nres tsheb hauv paus, lub zog hluav taws xob siv fais fab rau txhua tus qauv. There are four types of power supplies to the RF module board, namely 7.2V, 5.5V, 3.3V, and 2.5V, with a required accuracy of+1%. Qhov kub tshaj plaws ntawm lub hauv paus chaw nres tsheb lub khoos phis tawj lub khoos phis tawj yog qhov qub ntawm 15-30 degree, txwv tsis pub nws yog txawv txav. Cov av noo ntawm chav siv computer yog ib txwm nyob ntawm 40% thiab 65%, txwv tsis pub nws tsis txawv txav. Rau cov ntaub ntawv niaj hnub no, lawv tuaj yeem raug saib xyuas los ntawm kev kuaj mob ntawm DM3000 Digital Motimeter.
