Feem ntau txais yuav lub ntsuas ntsuas ntawm rectifier hom hluav taws xob ntsuas, electromagnetic electric meter, hluav taws xob ntsuas hluav taws xob thiab electrostatic hluav taws xob ntsuas. Tsuas yog cov electrostatic voltmeters, lwm voltmeters yog ua los ntawm me me ammeters thiab voltage dividers nyob rau hauv series. Ib qho hluav taws xob faib hluav taws xob tsim los ntawm ntau lub resistors kuj tuaj yeem txuas nrog hauv cov khoom siv ntsuas los tsim ntau qhov voltmeter. Cov koob ntawm AC voltmeters no nyuaj ua kom qis qis, qhov qis tshaj plaws yog nyob nruab nrab ntawm ob peb volts mus rau ntau kaum ntawm volts, thiab qhov siab tshaj plaws yog li 1 txog 2 kilovolts. Qhov qis tshaj plaws ntawm qhov ntsuas hluav taws xob hluav taws xob yog li 30 volts, thaum qhov siab tshaj plaws tuaj yeem siab heev. Lub high-voltage voltmeter siv nyob rau hauv lub hwj chim system yog tsim los ntawm ib tug electromagnetic voltmeter nrog ib tug rated voltage ntau ntawm 100 volts, ua ke nrog ib tug voltage transformer nrog ib tug tsim nyog voltage transformation piv. Vim qhov kev txwv ntawm cov coil inductance ntawm kev ntsuas ntsuas, qhov ntau zaus ntawm lub tshuab hluav taws xob voltmeter thiab hluav taws xob voltmeter yog nqaim, thiab lub siab txwv zaus qis dua 1 txog 2 kHz. Lub tshuab hluav taws xob yog me ntsis zoo dua li cov tshuab electromagnetic. Ob qho tib si electrostatic thiab thermoelectric voltmeters muaj ntau zaus. Lub sab sauv txwv ntawm lub rectifier voltmeter yog hais txog ob peb kilohertz, tab sis nws yuav tsum tau muab sau tseg tias lub rectifier meter nyeem ntawv tsuas yog muaj tseeb thaum lub AC voltage yog sinusoidal. Saib lub rooj rau qhov ntau, qhov ntau zaus, kev ua haujlwm sab hauv thiab qib siab tshaj plaws ntawm txhua qhov voltmeter ntawm txhua lub voltmeter.
