The world’s first voltmeter was the “electric force indicator” of the Russian physicist G. V. Rikhman (1745). A digital multimeter is a device which provides combined functionality of ammeter, voltmeter and ohmmeter. 2. The area of cross-Section of potentiometer wire must be uniform which is practically not possible. But there are more things that a digital voltmeter can do. It measures AC or DC voltage and displays the value directly in numeric form instead of pointer reflection. A digital multimeter is a device that provides the combined functionality of ammeter, voltmeter, and ohmmeter. A digital multimeter has an analog/digital converter that provides a digital readout. While measuring the voltage, there are chances of the digital voltmeter getting the heated up. Not compact in size. The reliability and repeatability are poor. But potential dividers also suffer from the disadvantages stated above. A hexagonal cell  method is on... Zigbee network technology is a wireless protocol used for wireless networking and connectivity. This increases the precision in reading the values. When the battery is low, the display will be dim, making it difficult to read. ", Advantages and disadvantages of Galvanometer, Advantages and disadvantages of digital multimeter, Advantages and disadvantages of an analog multimeter, Advantages of digital multimeter over the analog multimeter, Advantages and disadvantages of full wave rectifier, Advantages and disadvantages of floppy disk, Umbrella cell approach in mobile communication, Advantages and disadvantages of Zigbee networks, Advantages and disadvantages of pulse width modulation, Difference between cell splitting and cell sectoring, Advantages and disadvantages of conduit wiring system, Advantages and disadvantages of shielded twisted pair cable. Power consumption in an electronic voltmeter is much lower than that of an electromechanical voltmeter. It is very hard to spot the transient voltage spikes. The digital display of the output eliminates the human reading error. The instruments are robust, owing to the simple construction... Next Previous. Whenever you measure electrical equipment, you'll need a meter which can measure volts, amps, and ohms. This is difficult because of flow of current. Questions and answers.

It is most widely used due to its small size, price and ease in operation. Both series resistance meters and potential dividers cause current drain from the source. Electrical quantities are to be continuously monitored being very dynamic. Digital voltmeter is prone to damage if the voltage is increased beyond the limit. Also the meter leads can behave like an antenna loading a high frequency circuit, or adding a signal that should not be there. The disadvantages of measurement of power by three voltmeter method are overcome in this method. The interaction of fluxes produced by these two elements produces the deflecting torque. A Digital voltmeter is void of parallax errors. VTVM’s are used in high power AC measurements. It is one type of twisted pair cable. A hexagonal cell  method is on... Zigbee network technology is a wireless protocol used for wireless networking and connectivity. This might output the wrong readings. When a fluctuation occurs, these meters are unable to represent it and rather record an error or calculate a single reading. Although there are advantages and disadvantages to both kinds of meters, digital meters are usually better than analogue.
