DVM (Digital VoltMeter) - All You Need To Know

Nearly all of our everyday requirements we utilise are driven by the functions of electricity. This is precisely why the role of the Digital VoltMeter becomes all the more crucial in that regard. A Digital VoltMeter, as its name suggests is commonly used to measure and calculate the level of voltage at which various appliances - commonly air conditioners and computers - operate and function. These devices also help us in planning our energy management accordingly. 

 

Key characteristics of a Digital Volt Meter - 

 

  • A Digital Voltmeter is employed to estimate AC or DC voltage consumed by an appliance and for displaying the value directly in a numeric form on a graphic interface as opposed to using a pointer deflection.
  • It accurately estimates the input voltage by first transforming the analogue voltage to digital voltage and then using a convertor to display it in a number format.
  • A digital voltmeter is usually designed around a special type of analogue-to-digital. converter which is popularly known as an integrating converter.
  • Normally, the input range of a digital voltmeter is from 1V to 1000V.

 

The most common types of digital voltmeters available in the market include a ramp type digital voltmeter, an interacting voltmeter, a continuous balance digital voltmeter, a potentiometer digital voltmeter, and a successive approximation digital voltmeter. All of these different forms of voltmeters have their own unique specifications and can be used for a diverse mix of needs.

 

Benefits of Using a Voltmeter - 

 

  • One of the major advantages of using a voltmeter is that it eliminates the risk of human error. The readings relayed on a digital screen are 99.9% accurate as opposed to a human attempting to read an analogue meter.
  • Secondly, digital voltmeters are considered to be more stable and hence more reliable. They are used to measure both AC and DC voltage systems.
  • The modern digital voltmeters of today now come with storage and recording features as well, which ensures that readings can be stored for future processing and analysis.

 

The digital voltmeter, like similar functions such as smart metering & power metering, has made life easy for all of us. It has definitely gone a long way in easing the manner in which we conduct our operations. #SchneiderElectric is one of the brands which has spearheaded the digital revolution across the globe in domains including voltmeters, as well as a variety of fields in energy management, industrial automation, and electrical protection.
