A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) is a measuring instrument that can measure multiple electrical properties. A typical multimeter can measure voltage, resistance, and current, in which case can be used as a voltmeter, ammeter, and ohmmeter. Some feature the … Visa mer Precursors The first moving-pointer current-detecting device was the galvanometer in 1820. These were used to measure resistance and voltage by using a Wheatstone bridge, and comparing the … Visa mer Analog An un-amplified analog multimeter combines a meter movement, range resistors and switches; VTVMs are amplified analog meters and contain active circuitry. For an analog meter movement, DC … Visa mer Resolution The resolution of a multimeter is the smallest part of the scale which can be shown, which is scale dependent. On some digital multimeters it can be configured, with higher resolution measurements … Visa mer Any meter will load the circuit under test to some extent. For example, a multimeter using a moving coil movement with full-scale deflection … Visa mer Probes A multimeter can use many different test probes to connect to the circuit or device under test. Visa mer A quality general-purpose electronics digital multimeter is generally considered adequate for measurements at signal levels greater than 1 … Visa mer • Electronics portal • Electronic test equipment • Electricity meter Visa mer WebbFig. 8.14 shows one of the methods that a cheap multimeter uses to measure the RMS of a signal. V X is the signal under measurement. Assume that V X is a pure sinusoidal waveform, i.e., a signal such as the one shown in Fig. 8.13.Then the capacitor is charged up to Vm Volts (voltage drop of diode is neglected), where Vm is the peak value of voltage …
