Buying Guide for the Best Automotive Multimeters
So what should you be looking for before taking out your wallet? There are some basic features that automotive multimeters should have and more advanced ones if you’re working on a specific type of troubleshooting. What you’ll find in this buying guide may help you realize some of the best brand models of automotive multimeters.
What your automotive multimeter should have
- The first step to choosing an automotive multimeter is deciding on whether you should get a digital or an analog version. Digital automotive multimeters have built-in LCD displays where readings manifest in digits. In this case, automotive multimeters that show a specific number of digits will give you a more accurate reading. The analog version uses meters and requires manual settings. Some professionals prefer this kind of automotive multimeter.
- Safety features on automotive multimeters is a must. You will need the assurance that you won’t be electrocuted while in the middle of a diagnostic. Check for rubberized covers around the casing of the auto multimeter as it will stop the flow of electricity. You can have the most durable automotive multimeter in the world but if it doesn’t have any protective covering for the user, you may move on to the next model.
- You’ll want to look out for automotive multimeters capable of testing voltages for both AC and DC. AC or alternating current is easier to create and transmit while DC or direct current only travels at a distance to one point only. Because there are automotive multimeters that only measures one of them, it would still be handy to have one that reads both in case you run into certain kinds of electronics.
Finally, you should also be checking if the automotive multimeter has clear/high resolutions. When tasked with a very delicate job, you need to be able get a good measure of the electrical properties as accurate and precise as possible. If the brand model doesn’t have the level of sensitivity to give you what you need to accomplish the job, you could end up with a lot of mistakes.
