Nta ntawm Analog Multimeter_Cov yam ntxwv ntawm Analog Multimeter
Analog Multimeter
Lub analog multimeter yog ib qho cuab yeej siv los ntsuas DC tam sim no, DC voltage thiab 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 rau digital multimeter, nws yooj yim dua thiab intuitive.
Nta ntawm Analog Multimeter
1. Tsis siv neeg ntau yam, 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 hloov.
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.
Cov yam ntxwv ua haujlwm ntawm analog multimeter
Feem ntau muaj plaub kab kab ntawm lub taub hau ntawm ib qho analog multimeter, uas feem ntau sawv cev rau kev nyeem ntawv ntawm qhov tsis kam, voltage / tam sim no thiab qib.
Lub calibration ntawm txhua lub iav ntawm lub ohmmeter yog ua raws li qhov tseem ceeb hauv nruab nrab tsis kam. Yog li ntawd, thaum ntsuas qhov tsis kam, tus pointer yuav tsum tau muab tso rau ze ntawm qhov nruab nrab ntawm qhov ntsuas kom ntau li ntau tau kom txo tau qhov yuam kev. Lub calibration ntawm txhua cov ntaub ntawv ntawm ammeter thiab voltmeter yog nqa tawm raws li tag nrho cov nuj nqis. Yog li ntawd, thaum ntsuas, qhov qhia tus nqi ntawm tus pointer yuav tsum nyob ze rau tus nqi tag nrho raws li qhov ua tau kom txo tau qhov yuam kev.
Kev ntsuas ntawm qib yog ua tiav los ntawm kev ntsuas AC voltage. 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 qhov ntsuas hluav taws xob. Txij li thaum lub zog xoom yog qib thaum lub zog lmW tau txais ntawm 600W load, qhov hluav taws xob ntawm qhov load ntawm xoom fais fab theem yog xoom theem voltage.
Qhov ntsuas decibel ntawm lub xov tooj sib raug rau qhov qis tshaj ntawm AC voltage (10V qib).
Kev siv cov analog multimeter
Lub analog multimeter yog portable analog multimeter rau ntsuas tsis muaj zog tam sim no circuits. Nws tuaj yeem siv tsis tau tsuas yog los ntsuas cov khoom siv sib txuas lus me me, cov khoom siv hauv tsev, lub teeb kab hluav taws xob thiab ntau lub roj teeb, tab sis kuj siv nws cov haujlwm ntxiv rau kev txheeb xyuas Circuit Court thiab lwm yam.
