The voltmeter - a measuring device for determining the voltage and voltage in electrical circuits.

be connected parallel to the load or source of electrical energy.

The ideal voltmeter should have an infinitely high internal resistance. Therefore, the higher the real internal resistance voltmeter, the device has less of an impact on the object to be measured, and hence the higher precision and diverse applications.

Classification voltmeters

  • On the principle of operation:
    • electro - magneto-electric, electromagnetic,
    • electrodynamic, electrostatic, AC-DC converters, thermometers;
    • electronics - analog and digital
  • By appointment:
    • DC;
    • AC;
    • Switching;
    • phase-sensitive;
    • selective;
    • universal
  • On the design and method of application:
    • shield;
    • portable;
    • fixed

The main groups voltmeters :

  • Analog electromechanical voltmeters (magneto-electric, electromagnetic, electrostatic and electromagnetic) are measuring mechanisms with appropriate types of indicating devices. To increase the detection limit using extra resistance.
  • Analog electronic voltmeters in addition to the coil meter and additional resistances, contain instrumentation amplifier (AC or DC) which allows you to have lower limits of measurement (up to tens - units of millivolts or less), significantly increase the input impedance of the device, obtain a linear scale on a small range measure AC voltage .
  • Digital electronic voltmeters The principle of voltmeters discrete action is measured DC or slowly varying voltage electrical code using the analog-to-digital converter, which is displayed on the display in digital form.
