Digital Multimeters - Pillar of Electrical Testing equipments in Electronic Industry

Whether you are an engineer, Production Manager or involved in technical work in any Electronic Industries, R& D Departments or Power Plants Digital Multimeter acts as a pillar in accomplishing ample of tasks rapidly. In today's competitive world where everybody is busy in his/her own hustles & bustles & the entire world has become so digitized where time is the most crucial parameter so Digital Multimeter provides best solution in saving time by providing features like troubleshooting that too in a fraction of seconds. Multimeters are basically used to measure voltage, current & resistance by compiling different features in one unit & according to the requirement user can switch over to different tabs that are provided in it. Multimeters can be broadly categorized under two different categories & they are Analog Multimeters & Digital Multimeters. Analog Multimeters are basically based on Microammeter whose pointer generally moves over a scale calibration (comparing with a standard) for all different measurements that can be made but on the contrary Digital Multimeter usually display digits for all the different measurements that are performed. Multimeters are used in fault finding applications & troubleshooting electrical problems in a wide variety of Industrial & Household devices. Multimeters are used in those applications where accuracy is the prime concern. Switching over to the user's requirement multimeters can measure Voltage (direct & alternating), capacitance, frequency, resistance, current, conductance, duty cycle, Inductance, temperature etc. Digital Multimeters are even used to test continuity in various electronic circuits (sound of beep occurs if the circuit connection is true). A wide variety of sensors that are available in the market can even be attached with multimeter for a variety of measurement like Relative Humidity, Wind speed measurement etc. Multimeters cover a wide variety of price range starting from as cheap as $10 to as expensive as $5000 depending on the features, resolution, reliability etc. the user is opting for.

Today Multimeters have replaced Galvanometer & had brought laurels in Electronics Industry.Galvanometers were primarily used to measure resistance & voltage by using wheatstone bridge & comparing unknown quantity with a reference voltage but it was very time consuming process & Galvanometers were too bulky to be handled. Replacement of Galvanometers by Multimeters is a sign of development & revolutions that are made in Electronics Industry & yet to be made in upcoming years. Digital Multimeters have found their new grounds to establish because of its very high resolution, durability & accuracy in comparison with analog multimeters. The resolution of digital Multimeter is normally specified in digits of resolution. Display count which is most popularly used regarding resolution perspective can even be specified to specify resolution. Display count usually gives the largest number, or the largest number plus one that the multimeter's display can show, ignoring a decimal separator. For example, the display count of a 5 digit multimeter can be displayed as a 199999 display count or 200000 display count multimeter.

Accuracy is the top most priority parameter in Electrical Measurement devices. Digital Multimeters are designed in such a manner such that they indicate accuracy as a percentage of reading in addition to a percentage of full scale value. When user needs to switch for measuring voltage than top most thing to be kept in mind is that the input impedance of the multimeter should be very high in comparison to the circuit being measured else there is a possibility that accuracy may get diminish & operations may even be complemented.

Digital Multimeters have given new wings to Electronic Industry to fly & explore & had contributed a lot in Electronic Industries. That day is not far away when with new innovative techniques & solution Digital Multimeter will dampen its roots in Electronic Industry & will be more users friendly.
