Voltmeter yog hluav taws xob ntsuas instrument siv ntsuas muaj peev xwm sib txawv ntawm ob lub ntsiab lus. Cov voltmeters digital tso saib tus nqi ntawm AC los yog DC voltage ua ntsuas ncaj qha raws li tus lej discrete tsis yog tus taw qhia deflection ntawm qhov ntsuas tsis tu ncua xws li hauv cov cuab yeej analog.

Kuj tseem paub yog, dab tsi tuaj yeem ntsuas digital multimeter?

A digital multimeter yog ib lub cuab yeej xeem siv ntsuas ob los yog ntau tshaj qhov hluav taws xob qhov tseem ceeb - qhov tseem ceeb voltage (volts), tam sim no (amps) thiab kuj (ohms). Digital multimeters muab cov peev xwm ntsuas ntawm ib leeg-ua haujlwm ntsuas-voltmeter (rau ntsuas volts), ammeter (amps) thiab ohmmeter (ohms).

Qhov thib ob, ntau hom digital voltmeter yog dab tsi? Digital Voltmeter yog dav faib ua plaub hom.

Lawv yog:

  • Ramp Hom Digital Voltmeter.
  • Integrating Digital Voltmeter.
  • Nruam Balance Digital Voltmeter.
  • Ua tiav approximation Digital Voltmeter.

Tsis tas li ntawd, voltmeter ntsuas qhov voltage li cas?

A voltmeter ntsuas yog instrumental ntsuas qhov sib txawv ntawm hluav taws xob muaj peev xwm ntawm ob lub ntsiab lus hauv ib qho hluav taws xob hluav taws xob. Ib qho analog voltmeter ntsuas txav tus pointer hla ib qho kev faib ua feem rau lub voj voog hluav taws xob ; ib digital voltmeter ntsuas muab tus lej tso saib.

Dab tsi yog multimeter siv los ntsuas?

A multimeter los yog multitester, tseem hu ua VOM (volt-ohm-milliammeter), yog ib qho hluav taws xob ntsuas instrument uas combines ob peb ntsuas ua haujlwm nyob rau hauv ib chav. Ib yam multimeter ua tau ntsuas voltage, tam sim no, thiab kuj. Analog multimeters siv lub microammeter nrog lub pointer txav los tso saib kev nyeem ntawv.
