Whether you are an engineer, Production Manager or involved 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 whole world is becoming so digitized where time is the absolute most crucial parameter so Digital Multimeter provides best answer in saving time by providing features like troubleshooting that too in a portion 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 to different tabs which are provided in it. Multimeters may 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 level calibration (comparing with a standard) for many different measurements that may be made but on the contrary Digital Multimeter usually display digits for the different measurements which are performed.
Multimeters are found in fault finding applications & troubleshooting electrical problems in a wide variety of Industrial & Household devices smart phone meter . Multimeters are found in those applications where accuracy is 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 various electronic circuits (sound of beep occurs if the circuit connection is true). A wide variety of sensors that can be purchased in industry can also be attached with multimeter for a number of measurement like Relative Humidity, Wind speed measurement etc. Multimeters cover a wide variety of cost range beginning as cheap as $10 to as expensive as $5000 with respect 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 was very time consuming process & Galvanometers were too bulky to be handled. Replacement of Galvanometers by Multimeters is really a sign of development & revolutions which are made in Electronics Industry & yet to be made in upcoming years. Digital Multimeters have discovered their new grounds to establish due to the high resolution, durability & accuracy when compared with analog multimeters. The resolution of digital Multimeter is normally specified in digits of resolution. Display count which can 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. For instance, the display count of a 5½ digit multimeter may be displayed as a 199999 display count or 200000 display count multimeter.
Accuracy is the very best most priority parameter in Electrical Measurement devices. Digital Multimeters are made in such a manner such which they indicate accuracy as a portion of reading along with a portion 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 must certanly be high in comparison to the circuit being measured else there’s possible that accuracy gets diminish & operations could 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 far when with new innovative techniques & solution Digital Multimeter will dampen its roots in Electronic Industry & will be more users friendly.
