What to Consider When Buying an Automotive Multimeter
Before you whip out your credit card and place an order, there’s one more thing you need to know. Choosing the best automotive multimeter for your needs requires a bit more consideration, including these features and qualities:
- Display: First and foremost, you’ll want to choose a multimeter with a good display. It should be large and clear enough to comfortably read the measurements without having to squint.
- Accuracy: A multimeter is a measuring device, so it must always be accurate. You can check online reviews to ensure that the multimeter you’re buying has the accuracy needed for the kind of work you have in mind.
- Controls: Another important factor to consider is how the controls are designed and placed. Automotive multimeters typically have some combination of buttons, dials, and a rotary switch. Ideally, you should test those controls before buying the multimeter to ensure you like how they feel.
- Design and build: Next, be sure to consider the multimeter’s design and build, which are important for practical reasons. A durable multimeter is less likely to be damaged if mishandled, and a good design will make it more useful or handy.
- Additional Features: Lastly, always consider value-added features. Automotive multimeters have the same core features, but some have helpful extras. For example, models that test for temperature and decibels are particularly helpful when troubleshooting car troubles for overheating and noise symptoms.
Finding the best automotive multimeter for your needs is so much easier if you know what to look for. Then it’s only a matter of choosing the product that ticks the right boxes.
