How to choose a multimeter for your needs



In this post, I’m going to give you a clear understand about multimeter, what are they and how they are used. If you’re still new to this automotive diagnostic devices, I’m sure this post will help you a lot when choosing the best multimeter.

What is it?

What is it


A multimeter is an automotive device that is used to measure the electricity current, like the AC and DC or even resistance. With this brilliant device, you can have yourself an ammeter, an ohmmeter, and a voltmeter without using each type separately. This device is used by automotive experts to diagnose any malfunctions, therefore, enable them to find the cause of their problems. There are two types of multimeter, analog and digital. Analog multimeter has a bar which can show the exact detail of the electric current inside the devices. The users will have to adjust their multimeter in order to get the best result. The digital one is a little bit different, it often has a display screen that shows all the needed information.

How to choose?

So what to look for when buying a multimeter? This column here will give you the exact answer.


If you only testing current with the maximum 30V then you probably won’t have to worry about this. But when the circuit gets above that, you should really consider choosing a safe multimeter. You need to look for those with an internal blast shield. Devices with a sufficient input protection is really a good choice when dealing with this matter.

Digital or analog

Digital and analog


I’m not going to say which one is better, there is only the one that suits you more than the other. The analog one is usually known as VOM which stands for Voltmeter – Ohmmeter – Milliammeter. Like how it sound, the VOM can only use with three type of measurement. On the flip side of the coin, the digital meter often has more than just three, you can find very interesting additional features. But there is a problem with a digital multimeter, they often have a much larger impedance than the analog ones. Therefore, this can affect the sensitivity of your measurement.

What brand should you buy?

There are many types and brands on the market but only some of them can stand above others. Fluke is the firm that has been dominating the multimeter market for a long time and their products are always very good. You could also find your multimeter with Agilent, although they still haven’t caught up to Fluke.
