Advantages of Digital Voltmeter
Digital voltmeter has various advantages and some of them have been stated below
- Since it does not involve reading from a pointer, it eliminates the human error that are caused by reading at an angle. This means gross errors are now removed giving precise results.
- They are more reliable and stable as compared to analog voltmeters which are comparatively unreliable while making readings.
- The output from DVMs can be provided to memory devices for the purpose of storage. This means that we can directly store the result of digital voltmeter in devices like flip flops.
- We don’t require any extra manuals for using digital voltmeters as they are easy to read and give precise and accurate readings.
- Digital voltmeters are more durable than analog voltmeters. We say this because they provide accurate readings without being affected by external factors like atmosphere, temperature and moisture.
Working Principle of Digital Voltmeter
A voltmeter is a significant device used in electronics engineering for measuring potential developed across various devices. Depending on the requirements these voltmeters can be designed into two types that being digital and analog. In this article, we will briefly discuss the two types of voltmeters. Later we will study about digital voltmeter and the working principle behind it. We will also see the block diagram of a digital voltmeter and how it works. The digital voltmeter can further be divided into certain types and we will discuss them too. This description will include talking about their specifications as well. After the discussion, we will talk about the advantages and disadvantages of digital voltmeters which are considered while using digital voltmeters in some real-life appliances. This will conclude the article with some Frequently Asked Questions for user reference.
