Buying Guide for Beginners

Don’t worry if you’ve never purchased an automotive multimeter or aren’t sure what to look for. We can help you sort through the essential characteristics, figure out your unique requirements, and select the best automotive multimeter for you.

What is Considered Safe?

Working with electricity is never completely safe. But now, there are safety features and technology to make it safer. It’s not worth the risk anymore. If you are an electrician or an auto enthusiast, make sure the multimeter has a safety rating of at least CAT-III 1,000V and CAT-IV 600V. You can also look for a ceramic tube that will protect you from explosive currents.

Find Something Durable

Do you take your tools to work or to help friends? If so, you want a multimeter that will last. Look for features like rubber guards and scratch-proof displays. These features will help make sure your multimeter lasts long and is reliable.


The last thing you want to be concerned about when you’re beneath a car is how to grip your large variety of various tools and gadgets. The need for stands, holders, and magnetic attachments grows among professionals and frequent users. Make sure the ease of use matches your high-quality readings.

The Display and Weight

Different multimeters have different sizes. You should think about the size of your new multimeter. Will you need to put it in a backpack, on your belt, or in a toolbox? Make sure your new multimeter will fit into your lifestyle with ease.

When choosing a multimeter, you need to think about the brightness of the display. If you are going to do work under cars or in dark places, get one that is backlit. If you need to take readings quickly and often, then get one with sizeable clear text that is easy for you to read.

Battery Duration

If you will use your multimeter a lot, it is worth looking at the battery life. Buy a multimeter with long battery life if you don’t want to interrupt work to change or charge up batteries.

Features That You Can’t-Miss

People use different features in their cars, homes, and work. How you use these things will tell you which ones are important to you. For example, maybe you always forget what the temperature is inside your house. Or perhaps it would be nice if your car battery said how much power it had left before it died so that you can find a place to charge it faster. You need these features for yourself, or they are not worth spending money on them at all. Think about what you really want before buying something because even though one person might like one feature more than another person, they might not like the other features enough to purchase the product.

Features and Advantages

If you are an electrician, an automotive professional, or a hobbyist, you need to know what specs will work for your needs. Safety requirements are different depending on who is using it.

Different people use multimeters for other things. If you need a quick and accurate reading, then you will want to spend more money on your meter. If you’re not sure how much voltage or current you need, the same goes.

Price range

Cheap tools are not always the best. It is worth it to buy something expensive if you want a tool that will work and be of good quality. If you buy a cheap tool and it does not work, then it is time-wasting and frustrating.

If you have a budget, try to get the features that are most worthwhile. You should figure out from your work or hobby what is essential.

Level of Experience

Some multimeters are easier to use for beginners. If you think it will take a while to feel comfortable with your meter, get something simple that has safety features. You do not need all the options yet. A simple display and easy pattern are enough at first.

It All Comes Down to the End

Everyone has different needs and their own must-have features. But there are reviews that can help you to find the best options on the market right now. The Innova 3340 is suitable for those who want a lot of functionality, safety features, and ease of use. If you want to have a lower price, but want many features, get the Innova 3320. If you are not worried about having a low price and just want to have the best features, get the Fluke 88-5.
