5 Automotive Multimeters with Amp Clamp in 2023

Amp clamp is a special feature that distinguishes some multimeters from others in terms of efficiency of testing and measurement.

This feature allows you to measure the current and voltage of the circuit without breaking it. Most amp clamps allow users to measure AC and DC voltage and AC amperage. Some of these meters allow you to measure DC amperage using the probes provided with the clamp meter.

The right automotive multimeter with amp clamp is one that also allows the user to measure DC load using probes.

Here, we discuss the top five choices that are available for automobile testing and troubleshooting. We have selected these meters based on their performance, accuracy, ease, and durability. You can find beginner-level and advanced clamp meters in the list.

KAIWEETS HT206B Digital Clamp Meter





Measures temperature


Doesn’t measure small current

Let’s start with the basics. The unit is small and lightweight. You can carry it in your toolbox wherever you go. The handheld device allows you to measure current (AC/DC), voltage, capacitance, continuity, duty cycle, resistance, and temperature.

The accuracy is enough for a general multimeter for this range that can detect the origin of the electric problem in your vehicle. Of course, it doesn’t compare favorably to its pricey competitors but it’s fairly reliable for most automotive jobs. If you are using it for general testing, you will also get the max hold function that will record the peak reading taken for the job.

The CAT III 600V device gives different safety and efficient features including the non-contact voltage (NCV) function, an orange-colored backlight to warn you of high voltage and current, and the LoZ function to eliminate ghost readings.

For most readings the backlight is white. Some users have commented that the meter doesn’t offer the best display setting with a narrow screen. It makes reading difficult. The meter could do better with a screen that is at least half an inch wider.

You get a high accuracy rate for DC measurements which is good news for automotive testers. Note that you have to use the FUNC button to manually switch between AC and DC measurements; it will not switch after detecting the current itself.

The meter is designed to detect small changes in current of up to 0.02A. With this smallest detectable increment, the commendable multimeter can measure up to 600A of current. The best part is that the meter gives efficient and fast readings. So, you can complete your tasks promptly.

After fifteen minutes of using the backlight, it can auto-shutoff. This feature helps you save energy. But it can also create frustration if you are working on a lengthy task and want to keep taking readings for a long time.

The clamp doesn’t read DC amperage

This is another general-purpose multimeter that works great for most appliances and automobiles. You may want to go for heavier options if you want to work on hybrid or electric cars. But this one should work on most of the older engines.

Once it’s out of the box, the first thing you will notice about it is its compact size. Its size makes it perfect for every toolbox whether it’s for your home or your companion for on-site tasks. The carrying couch makes it an even more suitable option for on-the-go testing.

The design is ergonomic and efficient. You will notice that the meter is sturdy and you can use the knob with your thumb without using the other hand. Like many other clamp meters, this one can check conductors that are up to 1 inch wide.

You can use it to measure AC/DC current, voltage, resistance, diode, and continuity. You will have to use its probes to measure DC amperage on your vehicles. Its clamp amp only caters to AC amperage. You will have to switch between AC and DC measures to suit your circuit needs.

The best part is its accuracy. For vehicle testing and general purpose electric work, you can depend on this meter to offer up to 2% of accuracy.

You can use its data hold feature to keep track of measures. Also, it remembers the max value when you want it to hold it for you.

The thermometer probe is used for only testing the range of temperature in a circuit so you can rely on the actual number it presents.

The clamp doesn’t test DC load

The first feature you will notice about this multimeter is its price. At just around twenty bucks, you can get a spare automotive multimeter with an amp clamp that will go with you wherever you take your vehicle.  This is the multimeter you will use to diagnose the problem.

Don’t be fooled by its price point – it’s durable. Plus, it’s compact and ergonomic. You can use the clamp to read the AC amperage of any device. Use it around the live wire to test your automobile battery.

For measurements, this tester covers your needs for AC amperage, voltage, resistance, continuity, and diode testing. You can also use the thermometer probe that is included in the package to test the temperature. Its AC voltage range starts from 600mV and maximizes at 750V. The range for DC volt is between 600mV and 1000V.

The backlight is enough for you to read the measures in dim-lit areas. You can also use its data hold button to activate memory for that reading. The max hold function will store the maximum reading it has taken on a job.

A low battery indicator saves you from unpleasant surprises and saves your time.

The package also includes temperature test leads. This probe can test temperatures between a range of -40 degrees Centigrade and 1740 degrees Centigrade. You can also measure the temperature in Fahrenheit instead of Centigrade.
