The various types of Digital Voltmeters(DVM's) in general use are : (i) Ramp type digital voltmeter (ii) Integrating type digital voltmeter (iii) Potentiometric type digital voltmeter (iv) Successive approximation type digital voltmeter (v) Continuous balance type digital voltmeter A meter is a measuring instrument. Types of Ammeters, Voltmeters are discussed in the below section: Ammeters and voltmeters are classified as follows: Moving Iron Type (a) Attraction type (b) Repulsion type; Moving Coil (a) Permanent magnet type (b) Dynamometer type; Hot wire; Induction type; Electrostatic (voltmeter only) Some of the meters may be used for DC as well as AC measurements. Digital Voltmeter is broadly classified into four types. See our Privacy Policy and User Agreement for details. RAMP type DVM 7.

Integrating Type Digital Voltmeter. Looks like you’ve clipped this slide to already. analog and digital. Continuous Balance Digital Voltmeter 4. The voltage to be measured may be AC or DC. All types of digital meters are basically modified forms of the digital voltmeter (DVM), irrespective of the quantity that they are designed to measure. New microsoft office power point presentation, No public clipboards found for this slide, Student at INSTITUTE OF AERONAUTICAL ENGINEERING. digital voltmeters give a numerical display of voltage by use of an analog to digital converter. measuring electrical potential difference analog and digital. Construction of a digital voltmeter using the elementary concepts of embedded system is presented in this paper. Digital Voltmeter (DVM). In opposite of integrating type voltmeter in case of ramp type voltmeter sampling of input voltage in done at the ending of the whole process. Clipping is a handy way to collect important slides you want to go back to later. U A d o b e P h o t o s h o p A d o b e P h o t o s h o p 6 . If you continue browsing the site, you agree to the use of cookies on this website. Digital voltmeters have a numerical display of voltage by using an analog to digital converter. The servomotor replaced by electromagnetic logic. Electromechanical voltmeters and ammeters, including thermal-type instruments, represent early technology, but still are used in many applications. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Digital instruments, particularly digital voltmeters or multimeters are employed for measurement of analog quantities. Electrical parameters like voltage and current are inherently associated with electronics and with electronic engineers. Timing Diagram of Ramp type DVM 6. Digital Ohmmeter Digital Voltmeter Low-impedance Voltage Tester The low-impedance voltage tester has a very large current draw compared to other types of voltmeters and should never be used to test low-power circuits. There are two types of analog and digital multimeter digital type which are designed for different purposes. Unit 17, 5th Floor, No.40، Sarhang … For DC voltmeters PMMC instruments are used, MI instrument can measure both AC and DC voltages, electrodynamometer type, thermal instrument can measure DC and AC voltages as well. Digital meters give an output in numbers, usually on a liquid crystal display. About 12 results (0.43 milliseconds) Sponsored Links Displaying digital multimeter PowerPoint Presentations.
