Voltmeter - Functionality

In multimeter voltmeter is integrated.

Voltmeters, also called voltmeter, has been around since the early 1900s. Initially analog gauges were used, which indicated the output current by needle deflection. These were used as either a voltmeter or ammeter and could only display a value. Today mainly are digital measuring instruments with different functions, so-called multimeter used.

Voltmeters and other measuring devices

  • Voltmeter exist, like other gauges also, from a movement with associated, outwardly connected to the unit auxiliary equipment. A meter on the other hand would have used in construction in the housing accessories.
  • In the case of the voltmeter the measuring system is the scale and the parts of the machine that are necessary for displaying the Messertes. As additional equipment the parts like switches and rectifiers and resistors are referred to which are fitted one either outside on the housing or integrated into the housing.
  • In voltmeters today multimeters are usually used because can here measure different metrics such as volts, amps or ohms. A distinction is made between digital and analog gauges.

Operation of digital and analogue voltmeters

  • In order to measure the voltages, the measuring instrument is connected in parallel to the circuit to measure the prevailing voltage. Thus, measurement errors are avoided or kept as low as possible, the internal resistance of the device should be highly resistive.
  • Analog gauges are particularly well suited for monitoring small measure changes. Voltage fluctuations can be observed well by means of the pointer deflection. However, they also harbor many sources and reading errors as the measuring ranges are set manually and the assignment of the measuring range should be considered to scale.
  • With digital gauges the Einstelung relatively simple and the accuracy of the device is significantly higher. Due to the low proportion of mechanical components digital meters are also considerably cheaper to manufacture.

Whether you use an analog or digital voltmeter, does not depend on the operation of the instrument. Rather of the location and the frequency with which you need to measure voltages.
