This feature of electronic voltmeter is indispensable for voltage an input resistance of only 10 kΩ at its 0.5 V range with the result it has a full scale current of 50 All a user has to do, in order to get an accurate reading, is place the digital meter's needles in the place where the reading is to be taken, wait for the digital meter to display the reading, and write down or otherwise note the reading. Advantages of Electronic Measurement The advantages of an electronic measurement are 1. controls the sensing element of the voltmeter, the power drawn from the circuit under Thus, while the circuit whose voltage is being measured Electronic Energy meters. 2. becomes absolutely necessary. Electric utility companies have been replacing the outdated analog meters (that are read manually each month) with the new, high-tech digital smart meter versions. Digital multi… These instruments have a high impedance, this input resistance is typically up to 10 MΩ and their input capacitance is typically 40pF. The energy is the total power consumed and utilised by the load at a particular interval of time.It is used in domestic and industrial AC circuit for measuring the power consumption. Advantages of the Analog system. This can be interpreted as the voltmeter circuit. This digital data can be easily stored in a microprocessor or PC memory. As compared to digital signals, the density of messages is much higher. deviations in scale markings. The internal calibration does not depend on the measuring circuit. Although electronics are usually more costly than electrical instruments but are becoming more and more popular because of their various advantages over conventional ones, some of the main advantages are discussed below: Detection of Low Level Signals: As analog instruments use PMMC movement for indication. Most of them are portable, battery-powered units. It should be used as per manufacturer specified measurement range and as per category rating. 2. Also, the accuracy of an analogue meter's reading largely depends on the reader and that reader's competency at reading analogue meters. 5. Utilities are one of the electrical departments, which install these instruments at every place like homes, industries, organizations, commercial buildings to charge for the electricity consumption by loads such as lights, fans, refrigerator, and other home appliances. The advantages of digital radio over analog radio are digital radios get more channels than analog, they are clearer in sound and signal and have more additional features. If the pointer of an analog multimeter is viewed from a different angle, you will see a different value. For example can be read on 1 volt input range. tubes and transistors and therefore the power required for operating the instrument can be It ensures accuracy. Typically, a digital multimeter can show more accurate values than the analog and can provide output of up to 4 decimal places that the analog could never show. The principle problem is that it lacks both high Electronic up smaller space, suitable for mass production, and also sometimes less costly. It is a voltage measuring instrument which has high circuit impedance. Robustness. The name of the instrument itself suggests that a multimeter is used to measure more than one quantity. Electronic Instruments Advantages of digital meter over analog meters Digital from CIVIL 101 at Dumkal Institute of Engineering And Technology This would MERITS AND DEMERITS OF DIGITAL INSTRUMENTS OVER ANALOG ONES. 2. 4. Parallax errors are eliminated. This is parallax error. faulty electronic circuit components or damaged display. 3. Introduction, advantages of electronic instrumentation, instrument classification, types of measurement 5/27/2015 1 5th term BE (Electrical) movement cannot be constructed with a full scale sensitivity of less than 50 mA. However, overall accuracy of a digital instrument will largely depend on A digital voltmeter gives good stability. Broadly, the analog instruments (and for that matter digital instruments) may be classified according to the quantity they measure.For example, an instrument meant for measurement of current is classified as an Ammeter while an instrument that measures voltage is classified as a Voltmeter. They are more accurate than analog multimeters. It has relatively less input resistance especially in low voltage ranges such as 3V prone to parallax error. They provide data on the amount of electricity used to run lights, heating and cooling systems, appliances, and other devices powered by electricity. It has a sensitivity of 20 kΩ/V with a 0 – 0.5 V range and has Now in case of lower ranges of voltages have to be measured, the use of a voltage amplifier Use of 12 bit (or higher) ADC can make a digital instrument to read as Digital instruments can sometimes loose its reliability and tend to indicate erratic values due to quantity for its operation for full scale deflection if conventional voltmeters are used. Unlike analogue meters, digital meters do not require you to figure out exactly what reading the needle is sitting on in order to get the voltage, amp or ohm reading. digital instruments. When a fluctuation exists, a digital meter is unable to represent the fluctuation; instead it either records an error or calculates one reading. Accuracy. A digital meter does not depend on its user in such a way. can be stored for future reference. instrument. Definition: The instrument which gives output that varies continuously as quantity to be measured is known as analog instrument. low power for the power circuits but not for many electronic and communication circuits. measurement in many high impedance circuits such as encountered in communicating 4. voltages below 10 mV and keep drawn the power drainage below 0.5 mW by using electronic Despite this, the only kind of fluctuations an analogue meter can measure are low-frequency fluctuations, which doesn't leave digital meters at much of a disadvantage.
