How to Buy an Automotive Multimeter?
In this guide, we will take you through a few important factors that you need to consider while choosing your meter, most common applications, useful tips and tricks, and frequently asked questions.
Look at this section as an information desk for all your burning questions about automotive troubleshooting.
Why Should You Buy an Automotive Multimeter?
Having a good-quality automotive multimeter can help you diagnose common electrical issues with your vehicle.
One such example would be to test the battery of your car and check if it needs a boost or a replacement. All without depending on a mechanic.
While you can do this with a general-purpose meter, an automotive multimeter ensures more safety and is rated for high voltages.
If the high rating is not enough of an advantage, modern meters come with fabulous features that will turn you from a regular car owner to an enthusiast.
Features like temperature measurement, automatic ranging, flashlight, and battery health check meter are some extra bells you can find in multimeters today.
Therefore, it makes sense to make an automotive multimeter a part of your automobile toolkit.
Compared to how much a car costs you, getting a multimeter will be a fraction of that cost. But in the long-term, it will pay off by helping you keep your car in spick and span condition.
If you are still somehow confused about which one to buy, here’s a short buying guide that will help you make a perfect choice.
How to Choose a Multimeter For Automotive Use?
There are several factors that need to be considered while shopping for an electrical meter. But with an automotive meter, it is slightly different.
It basically combines different measurement functions into one.
Here are the most important parameters that you can take to judge your top choices with:
- Safety Rating – Consider the usage and location.
If you are going to use the meter in highly sensitive and static areas like production lines, you need to buy a meter that has a strong enclosure made of fiber and with a higher CAT rating. Most of the above meters are rated for CAT-IV (around 600V AC).
For the highest rated meter in our list, go with the Fluke 88V Automotive Multimeter.
- Type –
Analog meters are almost like artifacts today, used only by a niche group who prefer those types. Digital meters are robust, more accurate and easier to read, and come with a plethora of features.
- Ranging – You can either go with auto-ranging or manual mode (like regular DMMs).
Auto-ranging meters automatically detect the range of the quantity being measured and get you the exact value.
- Quantities – Look at what quantities the meter can measure.
Are you going to be needing a tool that also measures temperature? Then get one with a thermocouple (Fluke 88V).
Can’t think of a meter that does not measure capacitance? Don’t consider the ESI model.
It is also important to check the maximum ranges. For example, if you want to measure voltages above 1000V, you might have to go with Pro versions of the Fluke meters reviewed above.
Same goes for capacitance and frequency.
- Quality – This is a default parameter and one that you will not need to put efforts in.
Our reviews of the meters above should give you a good idea about the make and build of the meters. All six are highly accurate, while only a few of them give a true-RMS reading.
- Extra Quantities –
Other than usual electrical ones, the meter also needs to have the ability to test batteries, fuses, and coils since these are common applications in the automotive industry
- Features –
Jot down the top 5 features that you need and then get the meter that has a majority of them. This is the easiest trick in the book to find your ideal meter.
Most common features found in automotive multimeters:
- LCD backlight
- Non-contact voltage (NCV) or clamp
- Magnetic strap
- Sturdy carrying case
- Alligator clips/probes
- Li-ion batteries (as opposed to non-rechargeable AA)
- Beeper/variable sound
- Automatic shutdown
- LED pulse lights
Most Common Automotive Multimeter Applications
- Measure DC voltage, amps in a circuit, continuity, resistance, temperature
- Diagnose issues with ignition coil, fuses, switches
- Testing a car battery, alternator, or ignition
- Testing car speaker wires, woofers
- Checking coolant temperature, airflow
Most of these applications revolve around measuring common electrical quantities. The key is to know what to check, when, and how.
So, here are two examples…
How to Use an Automotive Multimeter?
Two Examples of Common Automotive Troubleshooting
1 - Testing a Car Battery
It is as simple as testing a 9V radio battery. You just need to connect the probes to the terminals of your car battery and select the range of 20V DC. Since most car batteries are in the 12V-15V range, this is a good range to select.
If the battery is in good condition, the meter will read a value near to the original rating of the battery. If it does, move to the next step.
Turn ON the ignition while keeping the meter probes connected to the battery.
If the reading drops a few volts and then increases to stay constant, you can confirm that your battery is capable of generating cold cranking amps (CCA) essential for the running of your car.
2 - Checking Coolant Temperature
Find out the location of the coolant temperature sensor and connect the probes of your multimeter to its terminals.
While the ignition is OFF, check the resistance of the sensor. It should be less than 3 kilo-ohms.
Upon ignition, the resistance should drop to less than 1 kilo-ohm.
If for any reason, these readings do not match, you may need to change the sensors or take your vehicle to an auto garage.
Few automotive testers have manual instructions for such common tasks. So, it might be a good idea to read them before operating.
Automotive Multimeter FAQs
How to measure current if a meter has different ranges?
Most multimeters have two ranges for current measurement. The mA range can be used for low current measurements whereas A range (up to 10A usually) is used for high current measurements.
Users should also note the rating if a meter can withstand continuous measurements of high current ranges.
How to replace fuses?
It is recommended that you do not meddle with the factory setting/enclosure of a meter. But in case of a blown fuse, you must switch OFF the meter and open it through the back cover.
Take the blown fuse to your nearest electronics store and get a replacement, possibly of the same brand. Alternatively, you can get in touch with the manufacturer.
Will I get a warranty if I purchase a meter from an e-commerce site like Amazon.com?
Most meters come with a manufacturer’s warranty, which is valid regardless of the medium of purchase.
Make sure you keep the invoice safely with you at least till the warranty period. Fluke and Tacklife are known to provide best customer support.
How to check the highest range for measurement of any quantity?
Checking the meter’s manual will be the best solution. Most meter manuals have complete information about the product.
Useful Tips and Tricks For Using an Automotive Multimeter
- Always wear insulated hand gloves while operating automotive meters
- Use the magnetic strap with caution (as most magnets are rare Earth types and are not strong enough)
- DO NOT open the back case of a meter
- If you want to, do it while wearing hand gloves and eye shields
- Consult a professional in case of blown fuses
