Kev piav qhia ntawm cov haujlwm thiab cov yam ntxwv ntawm analog multimeter
Analog multimeter
Analog multimeter yog ib qho cuab yeej siv los ntsuas DC tam sim no, DC voltage, AC tam sim no, AC voltage, thiab tsis kam. Nws feem ntau muaj peb ntu: qhia ib feem, ntsuas Circuit Court thiab hloov khoom siv. Piv nrog digital multimeter, nws yooj yim thiab intuitive.
Analog multimeter nta
1. Tsis siv neeg ntsuas hom, siab input impedance.
2. Qhov hluav taws xob thiab kev ua haujlwm tau txiav txim siab rau qhov tsim nyog tshaj plaws.
3. Tsis siv neeg polarity conversion.
4. 1-10Mω siab input impedance.
5. Series capacitor input hom.
6. Tsis xav tau kev hloov kho xoom.
7. Built-in roj teeb xyuas muaj nuj nqi.

Feem ntau muaj plaub kab kab ntawm lub taub hau ntawm lub 'meter' ntawm ib qho analog multimeter, uas sawv cev tiv thaiv, voltage / tam sim no thiab qib nyeem raws.
Lub calibration ntawm txhua theem ntawm lub ohmmeter yog nyob ntawm seb qhov chaw tiv thaiv tus nqi. Yog li ntawd, thaum ntsuas kev tiv thaiv, tus pointer yuav tsum tau muab tso tawm kom ze rau qhov nruab nrab ntawm qhov ntsuas kom txo tau qhov yuam kev. Lub calibration ntawm txhua lub iav ntawm ammeter thiab voltmeter yog ua raws li lawv cov nqi tag nrho. Yog li ntawd, qhov taw qhia tus nqi ntawm tus pointer yuav tsum nyob ze li qhov ua tau rau tus nqi tag nrho thaum ntsuas kom txo tau qhov yuam kev.
Kev ntsuas ntawm qib yog ua tiav los ntawm AC voltage ntsuas. Yog li ntawd, txawm hais tias qib tau txhais los ntawm kev noj cov logarithm ntawm lub zog piv, nws tuaj yeem hloov mus rau qhov ntsuas ntawm qhov voltage. Txij li thaum xoom fais fab theem yog theem thaum lmW lub zog tau txais ntawm 600W load, ces qhov voltage ntawm lub load ntawm xoom fais fab theem, qhov voltage tus nqi yog xoom theem voltage.
Qhov ntsuas decibel ntawm lub xov tooj sib raug rau qib qis tshaj ntawm AC voltage (10V qib).
