Complete Buyer's Guide to Best Automotive Multimeter

Automotive technicians and engineers rely on multimeters to test and diagnose electrical issues in vehicles. There are many different types of multimeters on the market, so it can be difficult to know which one is right for you. This guide will help you understand the features and applications of different types of automotive multimeters, so you can choose the best one for your needs.

Buying a multimeter without prior knowledge is dangerous for both, vehicle and you. So, here I mentioned some important features that you should consider before buying the best automotive multimeter.


The best multimeters for automotive use will have a clear and easy-to-read display. You'll want to be able to see the reading even in low light conditions, so look for a model with a backlit display. If the display is detachable or remote then it will be a plus point.

Auto-ranging Function:

The majority of automotive multimeters have an auto-ranging function. This means that you do not need to switch settings in order to get the correct measurement. For example, if you are trying to measure voltage and the meter is set on DC volts, instead of having to switch it manually between 20V, 200V and 2000V, it will automatically select the range for you. This is a very useful function, as it saves time and prevents errors.


All best automotive multimeters should perform multi-functions and electrical tasks easily. It must possess the latest features like auto-ranging, true RMS, and LoZ to avoid stray voltages. Also if you're looking for an automotive multimeter, it must be able to check all electrical faults and electronics. Unlike manual ranging multimeters in auto-ranging multimeter, you only have to select the variable and it automatically set the voltage ranges.


Durability is one of the most important factors to consider when looking for automotive multimeters. As its lifespan depends upon its usage and cost too. Therefore, it's important for professionals to use it perfectly.

Additionally, it's illogical to buy a multimeter that's not long-lasting. So, it's better to buy an all-in-one multimeter on your first try.

Price and Voltage Range

If you came here, it means you value your money. Therefore it's my responsibility to direct you to the right place. Most of the time, it depends on the brand. But giving a chance to new brands is also not a bad choice but you must have to check maximum ranges before buying the one. Lastly, being a technician myself I prefer to work with FLUKE 233 for my routine work.

How would you use a automotive multimeter to diagnose an electrical problem with a car?

To use an automotive multimeter to diagnose an electrical problem with a car, you would first need to identify which circuit or component is not functioning correctly.

Once you have isolated the problem area, you would then need to determine what voltage or resistance readings are normal for that particular circuit or component. If the readings you are getting from the multimeter are outside of the normal range, it is likely that there is an electrical problem.
