A Digital Multimeter is an electronic measuring instrument which combines several measurement functions in one unit. A Multimeter has various features such as it has the ability to measure current, resistance and voltage. Digital Multimeter usually displays digits but it may display length which is proportional to the quantity measured. Using it one can check the continuity of the circuit, diodes and transistors. The resolution of a digital Multimeter is specified in digits of resolution. Using it we can get accurate measurements.A signal under test is converted into voltage and an amplifier with controlled gain preconditions the signal. A digital Multimeter displays the quantity which is measured as a number by eliminating the parallax errors. Nowadays Digital Multimeters are designed with embedded computer which provides a wealth of convenient features. It is very much useful for the electronic engineers, students and technicians. It can provide an auto ranging display for faster measurements. Digital Multimeter is used for the basic functions such as educational applications, residential and for automotive. It is designed with manual ranging such as capacitance and temperatures. It is also used for trouble shooting and electrical maintenance. Automotive can test duty cycles, switches, solenoids and alternator diodes. With it one can make frequency, resistance, capacitance, current, voltage, temperature measurements and period with confidence. One can also monitor, view statistical values and record measurements to see the circuit’s performance. Nowadays it is used for finding electrical current. In this type of Multimeter one can test AC, DC volt, resistance, batteries, electrical inductance, electrical capacitance, frequency, diodes and DC current. It is designed with LCD screen for easy understanding. Most of the Multimeters are used to measure electrical current and electrical voltage. Digital Multimeter offers digital number for unstable signals or quick-changing. Digital Multimeters are used by everyone for its accuracy and speed. Anyone who want to know the exact measurements and distance they can use Digital Multimeter. Digital Multimeters are also made with various facilities such as Data hold, full icon display, low battery display, sleep mode, battery powered, transistor, continuity buzzer and diode function. Multimeters with streamline holster design, solid state protection, resistance mode, deluxe carrying case, manual and auto ranging, microcontroller based design, beep guard, overload protection, low voltage ohms, full function protection, metallic screen board with strong antimagnetic field and auto power off are also available in market.
