The ultimate guide to getting the Perfect Automotive Multimeter

Considering the types of automotive multimeters are a lot, it can be so difficult for you to get your hands on the best. With our buyer's guide, however, you'll at least get a head start on the most important things to look for before you put your money on the line.

Analog multimeters vs digital multimeters.

First off, let’s start with the basics, right? Regardless of why you are shopping for a digital multimeter, you’ll always have to make a choice between getting one that’s digital or one that’s analog.

It won't be difficult for you to tell the difference between these two since the analog multimeter uses a pointing needle while the digital multimeter uses a digital display to show the values. The latter in this case is obviously the best car multimeter which is also what you'll get on the market today.

When it comes to accuracy, digital multimeters are far much better to work with and the odds of you taking the wrong readings are much lower.

Auto-ranging multimeters vs manual ranging multimeters.

In this case, the automotive multimeter is entirely a personal opinion. If you’d love to have most of the work done for you, then you should probably go for the auto-ranging multimeters.

On the other hand, some people love to go step by step when troubleshooting their vehicles and in this case, you should go for the manual ranging multimeter.

If it’s your first purchase, then I’d highly recommend that you go for the auto-ranging multimeters. After all, they do save you the time and hassle of having to set the range yourself.

Cost vs performance

Yet another thing to pay attention to is whether or not it's as good as its price. Normally, I'd say that you don't sacrifice quality for the price. In the case of multimeters, however, it's only best that you go for something that will meet your day-to-day needs rather than going for something that's too expensive and won't be using it as often.

On the other hand, depending on your budget, you can go for a cheaper multimeter. At the same time, you should ensure that it does have what it takes to take care of the basic maintenance procedures such as voltage and current measurement flawlessly.

The accessories.

The car multimeter is totally different from the basic multimeters we are used to. the reason for this is quite simple. For a car, the work to be done is way too much as compared to basic electronics.

Besides the automotive multimeter itself, you’ll always have the test probes that come along with it. you’ll be needing the normal test probes and in addition to this, alligator clips as well as IC hooks.

If you’re lucky enough to get an automotive multimeter kit, you may get all three which saves you the trouble of shopping for what’s missing.

The multimeter’s build.

On the outside, it may be difficult to tell apart an automotive multimeter from the one you’ll use for basic home maintenance. Even so, comparing the construction of either, an automotive multimeter should be far much better off.

For starters, it is best that it has a protective rubber guard all around it. this is to ensure there’s no risk of damaging it just in case you are working outdoors and you happen to drop it.

Another area of concern is whether or not it is rugged enough to withstand wear and tear. Since you’ll mostly be doing automotive work, it is best that the multimeter you’re working with be able to take quite a beating and still work effectively.

Some additional construction details you should look for in the automotive multimeter is whether or not it's got a strap that allows for hands-free usage as well as a kickstand.

Accessing the fuse and batteries should also not be much of a problem. Rather than going for one that requires you to remove the whole back panel, you should go for one that has a separate battery and fuse compartment.

Additional features.

Besides just having a god construction, there are some extra features that would come in handy on an automotive multimeter.

The min/max function, as well as the data, hold functions. The former allows you to store either the highest or the lowest value regarding a certain unit. This comes in handy when you need to keep track of your measurements. For the data hold, you'll simply be able to freeze the current values displayed on the screen for as long as you want to.

A backlight display.

The automotive multimeter will always have this feature. Even if you won't be doing most of your automotive maintenance under dim light, there's no harm in getting a backlit display. it will definitely come in handy at some point, don't you agree?

Using your automotive multimeter

When it comes to the actual maintenance of your vehicle using an automotive multimeter, there’s actually quite a lot that you’ll be able to do.

Here’s how an automotive multimeter could come in handy…

Testing your car battery

In some cases, you may doubt that your battery is running low on power. With a multimeter, however, you can know whether or not this is actually true.

All you have to do is locate your car battery and with reference to the manual, go ahead and disconnect the cables from the battery. Having done so, use a 20-volt DC reading for the sake of accuracy.

You should hook up the red probe to the positive terminal of the multimeter and the black probe to the negative terminal and you’re good to go.

Testing your audio system

Something as simple as knowing which the positive wire on your speaker is to knowing the ohm measurement on your subwoofer, a multimeter can definitely do the trick.

For testing the wire polarity, you should first set the multimeter to 20V DC and have the probe to one of the chassis grounds. The red probe should, on the other hand, be on either of the other terminals.

For the one with voltage, you’ll notice a voltage reading on your multimeter.

For ohm measurement, just in case you want to install a subwoofer, first of all, hook up both ends of the multimeter to the amplifier's speaker terminals. Set the multimeter to 200 ohms then check whether the level of ohms on the multimeter is at par with the rating on that of the amplifier.

Troubleshooting your airflow meter

Located at the outlet of the top cover of your air cleaner is the air flow meter. After disconnecting this and removing it, you can check its resistance using your multimeter.

Just ensure that the ohm rating you have set on your multimeter obeys the specification of your vehicle.

The fuel temperature sensor.

Found in the body of the fuel pump is the fuel temperature sensor. Before you test it, you should turn off the car and then disconnect the wiring. Go ahead and check the resistance reading.

The value you’ll get has a wide range but it has to be anywhere between 0.5 ohms and 3.0 ohms; if otherwise, then you may have to replace the fuel pump.

The coolant temperature sensor

This one’s located in the cylinder head and as the temperature of the sensor increases, the resistance value will decrease and vice versa.

Start off by switching off the ignition switch and disconnecting the wiring plug from the intake air temperature sensor.

Check the resistance between the terminals and with a cool engine, it should be anywhere between 2.0 and 3.0-kilo-ohms. With the engine warmed up, this value should range between 400 and 700 ohms.

If you don’t get these values, you should probably get a replacement.
