Whether you are an engineer, Production Manager or associated with 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 & in line with the requirement user can switch to different tabs that are provided in it. Multimeters could be broadly categorized under two different categories & they are Analog Multimeters & Digital Multimeters. Analog Multimeters are basically based on Microammeter smart multimeter whose pointer generally moves over a scale calibration (comparing with a standard) for many 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 selection of Industrial & Household devices. Multimeters are used in those applications where accuracy could be the prime concern. Switching 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 several electronic circuits (sound of beep occurs if the circuit connection is true). A wide selection of sensors that are available in the marketplace can also be attached with multimeter for a number of measurement like Relative Humidity, Wind speed measurement etc. Multimeters cover a wide selection of price range beginning with as cheap as $10 to as expensive as $5000 with regards to 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 guide voltage but it had been very frustrating process & Galvanometers were too bulky to be handled. Replacement of Galvanometers by Multimeters is a sign of development & revolutions that are produced in Electronics Industry & yet to be produced in upcoming years. Digital Multimeters have discovered their new grounds to establish due to the high resolution, durability & accuracy in comparison with analog multimeters. The resolution of digital Multimeter is generally specified in digits of resolution. Display count that will be most popularly used regarding resolution perspective can also be specified to specify resolution. Display count usually gives the largest number, or the largest number plus one which the multimeter’s display can show, ignoring a decimal separator. As an example, the display count of a 5½ digit multimeter could be displayed as a 199999 display count or 200000 display count multimeter.
Accuracy is the utmost effective most priority parameter in Electrical Measurement devices. Digital Multimeters were created 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 taken into account is that the input impedance of the multimeter ought to be high in comparison to the circuit being measured else there’s possible that accuracy could get diminish & operations can even be complemented.
Digital Multimeters have given new wings to Electronic Industry to fly & explore & had contributed a great deal in Electronic Industries. That day isn’t a long way away when with new innovative techniques & solution Digital Multimeter will dampen its roots in Electronic Industry & could be more users friendly.
