A digital multimeter is a device which provides combined functionality of ammeter, voltmeter, and ohmmeter. We commonly know it as DMM. It is most widely used due to its small size, price, and ease in operation. A digital multimeter has an analog/digital converter that provides a digital readout. This increases the precision in reading the values.

Advantages of Digital Multimeters:

  • They are more accurate than analog multimeters.
  • They reduce reading and interpolation errors.
  • The ‘auto-polarity’ function can prevent problems from connecting the meter to a test circuit with the wrong polarity.
  • Parallax errors are eliminated. If the pointer of an analog multimeter is viewed from a different angle, you will see a different value. This is a parallax error. A digital multimeter’s numerical display solves this problem. (buy digital multimeter)
  • Digital multimeter displays have no moving parts. This makes them free from wear and shock failures.
  • The digital output is suitable for further processing or recording and can be useful in a rapidly increasing range of computer-controlled applications.
  • Accuracy is increased due to digital readout. You can make a mistake in reading the scale in analog multimeter, but digital multimeters have an LCD display to show accurate reading.
  • The ‘auto-ranging’ feature of a digital multimeter helps in selecting different measurement ranges, which can prevent damage to the meter if the wrong range is selected.
