Lub multimeter tseem ceeb npaum li cas rau tus kws tshaj lij?
Multimeter yog ib qho ntawm cov cuab yeej tseem ceeb tshaj plaws rau cov neeg siv hluav taws xob, vim yog kev ua haujlwm yooj yim, kev ntsuas tag nrho, kev nyab xeeb, los ntawm feem ntau ntawm cov neeg siv hluav taws xob nyiam. Lub hauv paus tuaj yeem hais tias yog manually, thiab muaj qhov ntsuas ntawm on-off, voltage, tam sim no, firewire, NCV, thiab txawm tias qee yam khoom siv hluav taws xob thiab qhov kub thiab txias, xws li omnipotent, kev muaj peev xwm muaj zog tshwj xeeb, uas tseem yog lub hauv paus ntawm lub npe ntawm lub multimeter.
Multimeter yog ib qho cuab yeej siv ntau lub hom phiaj ntsuas, qhov yooj yim tuaj yeem muab faib ua ob pawg: hom pointer thiab digital zaub hom. Cov zaub digital kuj yog ib hom siv ntau tshaj plaws niaj hnub no. Cov zaub digital yog qhov feem ntau vim nws qhov kev nyeem ntawv yooj yim thiab ua haujlwm yooj yim. Nyob rau hauv tsos yog ib tug ntau yam ntawm, vim hais tias ntawm no, nyob rau hauv kev saib xyuas thiab sim zoo tshaj pointer multimeter.
Multimeter siv peb yam:
(1) Multimeter
1: Ua ntej ntsuas, xyuas tias lub tshuab multimeter tsis zoo thiab nyeem kom raug. Lub 'meter' cwj mem tsis zoo. Cov ntawv txuas tsis zoo. Tshwj xeeb tshaj yog thaum ntsuas high voltage, xyuas kom cov rwb thaiv tsev ntawm lub meter cwj mem yog qhov zoo.
2: Xaiv cov iav tsim nyog raws li cov khoom yuav tsum tau ntsuas, xaiv cov iav hluav taws xob rau qhov hluav taws xob, cov iav tam sim no rau tam sim no thiab ohm iav rau kev ua haujlwm. Lub 'meter' cwj mem yuav tsum tau muab tso rau hauv qhov tseeb jack. Thaum ntsuas qhov hluav taws xob thiab kev tiv thaiv, tus cwj mem dub tau muab tso rau hauv qhov chaw nres nkoj COM, thiab tus cwj mem liab tau muab tso rau hauv V / Ω chaw nres nkoj.
Cov lus ceeb toom tshwj xeeb: Thaum ntsuas qhov ntsuas hluav taws xob, lub ntsuas hluav taws xob yuav tsum tsis txhob muab tso rau hauv qhov chaw nres nkoj tam sim no, vim tias nws yuav hlawv tawm lub ntsuas hluav taws xob yog tias nws lub teeb, lossis ua rau hluav taws xob poob yog tias nws hnyav.
(2) Meter cwj mem
Txhua multimeter nrog tus cwj mem yog tsim nyog rau lub multimeter, thaum tus cwj mem puas, thaum lub multimeter yuav tsum tau them sai sai rau qhov haum tsis.
(3) Kev ntsuas khoom
Hauv kev ntsuas kev tiv thaiv, kev tiv thaiv kom tsis muaj zog, nyiam dua los ntawm kev sib txuas ntawm Circuit Court, kev ntsuas yuav tsum tau ceev faj tsis txhob tiv tauj nrog ob txhais tes los yog cov hlau ntawm ob lub cwj mem, kom tsis txhob nyeem ntawv tsis raug. Voltage resistance ntsuas yog nyob rau hauv parallel thiab ntsuas tam sim no nyob rau hauv series. Thaum koj tsis paub tus nqi kwv yees, koj yuav tsum ntsuas los ntawm cov iav loj tshaj plaws, thiab txo qis nws mus txog thaum lub iav tsim nyog.
