![]() It can be also used to check of a diode and transistor etc. Mostly, DMM meter can measures basic and advance electrical quantities such as current, resistance, voltage, capacitance, inductance etc. Normally, AVO meter measures the basic electric qualities such as current, voltage and resistance. ![]() To measure the basic electrical quantities as well as test various electronic components such as diode, transistor and capacitors etc. To Measure the Current in amperes (A), Voltage in Volts (V) and Resistance in Ohms (c). A Galvanometer is a combination of resistors and trimmers are used to measure the current.ĭigital Multimeter is a combination of complex electronics parts such as digital display as LCD, Analog to Digital Converter (ADC), Comparator, Encoder, Logic components etc.Īnalog Multimeter (AMM or AVO Meter) primarily measures the current using a Galvanometer.ĭigital Multimeter (DMM Meter) measures voltage using Analog to Digital Converter (ADC). It can also be used to check different electronic devices such as capacitor, transistor and diodes etc.Īnalog Multimeter is permanent magnet moving coil Galvanometer. FeaturesĪn Analog Multimeter is a device used to measure limited electrical quantities such as Current, Voltage and Resistance etc.ĭigital Multimeter is a device used to measure multiple electrical quantities such as Current, Voltage, Resistance, Capacitance, Diode values, Transistors etc. There are key differences between an Analog Multimeter and Digital Multimeter which are shown in the below table as comparison. ![]()
