Advantages of Digital Meter Over the Analog

Digital and Analog multi-meter devices are both the same equipment in measuring various characteristics of an electronic components. However, there are some differences between these two tools. Many Technicians, Students and Hobbyist do prefer the use of the DMM (Short term for Digital Multi-Meter) over the traditional Analog VOM (Short term for Volt Ohm Meter) and vice-versa. For whatever reason, users have their own reason.

On this post, we will be dealing about the advantages of using the Digital Meter DMM over the classic Analog type VOM. It is already assumed that you have already seen these two types of electronic equipment, hold them on your hands and adjusted the settings to a certain level. If you are a student then you can go to the lab and borrow the equipment provided by your school. Hobbyist can buy this tool at a cheap prices and there are hundreds of them that are available on the market.

Anyway, what are the Advantages of the DMM?

Output Display

It is easy to gauge a reading through digital multi-meter since the output is automatically displayed in numbers through a Seven Segment Display. Unlike the analog type, you need to take a closer look into the meter scales and read the values. It takes time and human errors could occur especially for those who have poor eyesight.


Accuracy

Digital-Meters shows more accurate values than the Analog. Depending on the type of equipment that you are using, it can output up to four decimal places that the Analog type could never show.

For some reasons, the output generated by the digital type is unstable. It often changes with slight increment value that goes up and down. Most likely, anyway values within the range of fluctuations is considered valid.

Auto Polarity

You can read negative values and a good example is voltage. Placing the probes into the opposite polarity will result into a negative output. This is the huge advantage of making use a DMM over the VOM since doing this on the analog type can cause the equipment to be broken.

VOM

Today, both type of these tools are currently being improved by the manufacturers. You can find on the market some advance multi-meter tools that can provide you with graphical display and other data. This helps that user reduce the effort and time in manually calculating the data and minimize the errors that can be encountered.
