While buying an automotive multimeter, you should consider a product that can measure voltage, current, resistance, continuity, duty cycle, capacitance, frequency, temperature, and true RMS among others. Specifically, the best fluke multimeter for automotive should be able to suit your intended utility. Also, if you intend to work on an electronic system, you can opt for a high-end model as a one-stop meter.

You may also find some deluxe automotive-centric multimeters that even measure even Revolutions per Minute (RPM). Therefore, there is a wide range of multimeter models, and a quality automotive multimeter should exceed your current intentions for future proof. In addition, you should opt for a digital display for easy reading of measurements. Fortunately, all the recommended products on our list are built with a digital display.

2. Auto-Ranging or Manual Ranging

Besides the measurement capacity of a multimeter fluke accessory, you also need to check for its ranging function. Depending on the different measurements your device can handle, a ranging function works measurement appropriate for each performance. Under this consideration, an auto-ranging digital multimeter automatically selects different ranges for you. Alternatively, a manual range meter requires a user to select the suitable range before a specific measurement.

Luckily, most contemporary automotive multimeters are built with an auto ranging digital multimeter, for an operator's convenience. Nonetheless, always look out for the range limits of the model you choose. Therefore, always ensure you acquire a multimeter with manual or auto range limits that suit your intended applications. Moreover, the best multimeter measurement ranging should be able to measure milliamps for low current units such as sensors.

3. Ergonomics and Design Features

There are basic features that any quality multimeter should have for comfort and efficiency. For instance, it should be easy to use. Other handy features that supplement the functionality of a multimeter include a carrying case, backlit control panel, holsters, hanging kits, and test probes, among other features. Design features of any meter work to make work a breeze for optimal outcomes.

Among the some included ergonomic features, some are a necessity rather than a luxury. For example, a backlit panel is vital regardless of the utility because there are higher chances of working in low-light environments. Furthermore, a multi-functional meter with a kickstand and a magnet is deemed to be have an enhanced functionality. Even though fluke meters lack in-built magnets, separate magnet hangers are available.

Apart from easy application, there are other special features that serve as complimentary. For example, some multimeters have a data hold functionality that seamlessly conveys data on your mobile phone through an App. Such a special feature works to add to the convenience and easy application.

Lastly, you should also check for safety features on your multimeter of choice. Most quality and reliable multimeters are considered harmless, but you should recheck their safety just to be sure. Considering that products in the category are electrical in nature, they should protect a user from electric shocks. Therefore, don't ignore any red flag that might compromise your safety, even for renowned brands.

4. Versatility

In this context, we are review information about automotive multimeters. Nevertheless, it would help to buy a fluke meter that is versatile to diverse electrical functions beyond vehicles. According to most professional auto technicians, the best multimeter should be able to diagnose home electrical faults. Overall, a quality vehicle multimeter should have increased versatility for quality functionality and enhanced reliability.
