Applications of Digital Voltmeter
DVM is a useful device and has many applications like:
- It is used in laboratory and labs for determining accurate and precise voltage level across various devices mainly resistors, diodes, capacitors in electronics circuits.
- Often times unknown current values are determined with the help of DVM. As DVM helps to calculate voltage and once voltage level is known we can calculate the corresponding current in the circuit.
- DVM are employed in for verification purposes like they are used in cathode ray tubes to verify the accuracy of the findings and readings. They help in electrical maintenance and inspection of circuits.
- In certain circuits tree ammeter method and the three voltmeter method are used for measuring of power. They are used to calculate the power factor of a specific load in circuit.
- DVM is largely used for the purpose of circuit designing and prototype. They help in measuring and verifying voltage levels at every stage. This is used for designing the required circuit.
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.
