Cov yam ntxwv ua haujlwm ntawm cov multimeters
Feem ntau cov kab teev plaub kab ntawm lub ntsej muag sib deev, sawv cev rau kev nyeem ntawm kev tiv thaiv, voltage / tam sim no, thiab qib.
Kev ntsuas hluav taws xob ntawm txhua qib ntawm Ohmmeter yog raws li nws lub chaw muaj nuj nqis tiv thaiv, yog li ntsuas qhov ntsuas, tus pointer tiv thaiv, tus pointer tsis kam muab tso rau hauv nruab nrab ntawm qhov ntsuas tau kom txo tau qhov yuam kev. Kev ntsuas hluav taws xob ntawm txhua qib ntawm Ammeter thiab Voltmeter yog raws lawv cov kev paub tag nrho- nplai tseem ceeb. Yog li ntawd, thaum ntsuas, tus pointer yuav tsum tau muab tso rau kom ze li tau rau tag nrho - nplai muaj nqi los txo qhov yuam kev.
Qhov ntsuas ntawm qib yog ua tiav los ntawm kev ntsuas ntawm AC voltage. Yog li, txawm tias qib tau txhais los ntawm kev coj lub logarithm ntawm lub zog sib piv, nws tuaj yeem hloov mus rau kev ntsuas ntsuas ntawm voltage. Txij li lub zog xoom yog qib uas LMW fais fab tau txais ntawm 600W load, tus voltage qib voltage yog xoom qib voltage.
Lub decibel nplai ntawm lub xov tooj sib raug rau qhov qis tshaj ntawm AC voltage (10V qib).
Kev thov ntawm analog multimeter
Ib qho analog motimeter yog lub portable analog multimeter pultometer siv rau kev ntsuas tsis muaj zog hluav taws xob. Nws tuaj yeem siv los ntsuas qhov voltage ntawm cov khoom siv me me, khoom siv hauv tsev, thiab ntau yam roj teeb tshuaj siv nws cov haujlwm ntxiv.
Cov yam ntxwv ntawm analog multimeter
1. Tsis siv neeg cov chaw ua haujlwm, siab cov ntsiab lus impedance.
2. Voltage thiab kev tawm tsam yog cia li teeb tsa rau ntau yam.
3. Tsis siv neeg polarity hloov dua siab tshiab.
{{0 {}} m ω siab cov tswv yim tawm tswv yim.
5. Series capacitor cov tswv yim hom.
6. Tsis tas yuav xoom.
7. Ua tau nyob rau hauv roj teeb tshuaj xyuas kev ua haujlwm.
