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.
