What are the advantages of digital multimeter over analog multimeter

Here that main advantages of digital multimeter over analog multimeter:
  • A digital multimeter provides better accurate results.
  • They reduce reading and interpolation errors.
  • Portable size makes it easy to carry anywhere.
  • They have very high input impedance.
  • This meter can cause less meter loading effects on the circuits being tested.
  • The input impedance or resistance of DMM is quite high. Hence it does not the measurement much. Hence some precise measurement can be achieved.
  • This meter can cause less meter loading effects on the circuit being tested.
  • Nowadays some advanced digital multimeter has microprocessors and can store the reading for further processing.
  • They are very simple to use unlike the analog multimeter as results are displayed in numeric value directly users need not have to read manually from the scale.
  • Digital multimeter displays no moving parts. So this makes them free from wear and also a shock failure.
  • Unlike analog millimeters, zero adjustments are not required.
  • The reading speed is increased as it is easier to read.
  • All the advanced measurements such as frequency, impedance, transistor, the capacitance can be performed by DMM, unlike analog meter counterparts.
  • The digital output is suitable for further processing or recording and can be useful in a rapidly increasing range of computer-controlled applications.
  • The meter has protection against undesired input range. Hence the meter can be protected from overload or some of the fault or misuse.
  • The auto polarity function can prevent problems from connecting the meter to a test circuit with some wrong polarity.
  • Overall accuracy is increased due to digital readout. When you have used, you can make a mistake in reading the scale in analog multimeter, but digital multimeter has an LCD display to show accurate reading.
  • With the advent of an integrated circuit the size, cost and power requirement of digital multimeter have been drastically reduced.
  • Parallax errors are eliminated. If the pointer of an analog multimeter is viewed from a different angle you will see some of the different values. This is called the parallax error, which is solved digital multimeter to solve this problem.
Considering some above points mentioned above in the advantages of DMM compared to analog, I personally would prefer the digital multimeter for its high accuracy and more sleek nature. I hope this article proves to be informative if you are going to buy a multimeter.
