Question

What are the advantages of digital voltmeter?

Answer 1

Digital Voltmeter: -

1. The digital voltmeter is a voltage measurement tool that is frequently used. The unknown input voltage is converted to a digital value using a digital voltmeter (DVM), which then shows the voltage in numeric form.
2. An integrated converter is a particular class of analog-to-digital converter that is typically the foundation of DVM designs.
3. Input impedance, temperature, and fluctuations in the DVM's power supply voltage are just a few of the variables that might affect the accuracy of the DVM.

Advantages of Digital Voltmeter: -

1. Readings are accurate and fast compared to analog meters.
2. Digital voltmeter is more stable and reliable.
3. Smaller in size and cost-effective.
4. DVM can measure both AC and DC voltages of the electrical appliances
