Types of Multimeter The process described above is true only to multimeters classified as digital models. This post mainly introduces the basic information of multimeters, applications, and types of multimeters are in. For AC voltage or current measurement, the same principle is applied, except for the fact that the AC parameter to be measured is first rectified and filtered to get the DC parameter and the meter indicates the RMS value of the AC signal. Coriolis mass flow meters. Types of multimeter include two probes like red and black & two or three ports. Multi means many. Mechanical flowmeters measure flow by using an arrangement of moving parts, either by passing specific, known volumes of a fluid through a series of gears or chambers (in the case of positive displacement meters) or by means of a spinning turbine or rotor in an arrangement called a turbine flowmeter. In this method, if the multimeter is connected unexpectedly without selecting the range then there will be a little chance to damage the multimeter. The adjustment of power utilization can be done through multiplying the reading of voltage with the amps. The only difference is that a digital multimeters LCD screen shows the measurements in the form of numbers. They usually have a single twist knob to select the type of testing you need to do . Turning the selector switch in the mains voltage (V) direction to the multimeters maximum measuring limit will show the electric voltage or voltage in a circuit. Incorrect because of the earths magnetic field effect. Analog Multimeter Analog multimeter is the oldest form of a multimeter.
