When tackling DIY projects that involve any kind of electrical wiring, components, or circuitry, you need a multimeter on hand. These handheld devices measure electrical properties such as voltage, current, and resistance, allowing you to confirm that a system is operating properly or, when it’s not, recognize and diagnose issues. Whether you’re troubleshooting HVAC systems, repairing appliances, or testing car batteries, multimeters help you get the job done with minimal guesswork.
When choosing a multimeter, it’s important that you have an idea of the task you need it to perform. All models provide basic functions like checking for current and measuring voltage and resistance—these will be enough for a range of light-duty tasks. If you’re just interested in projects like testing car batteries, outlets, extension cords, or wall switches, you don’t need anything more than a basic multimeter.
More advanced models offer superior functions like frequency (used for troubleshooting too low or too high Hertz in electronics like speakers), continuity (to detect open or short circuits between two points), capacitance (the ability of an object to store an electrical charge), and temperature (using a thermocouple attachment). The most basic models also usually can’t measure alternating currents—only direct currents.
This model also offers True-RMS capability, ensuring maximum accuracy regardless of the type of current you’re dealing with. Its auto-range makes it easy to use as well, reducing the chances of inaccurate readings.
Flukes are unquestionably the best and are durable, however some cheap meters can be a good value for performance but none are as durable as a Fluke.
In a recent high-profile case, Nissan has recalled over 440,000 vehicles due to a potential engine bearing defect that could lead to engine failure and increase the risk of a crash.
In this article, we’ll explain what engine bearings are, why they’re important, common causes of bearing failure, how to identify early warning signs, and whether diagnostic tools like OBD2 scanners can help.
Every car diagnostic process should begin with a VIN check, because the VIN lays the foundation for what your Autel OBD II scanner will detect.But here’s what it doesn’t tell you:Your car’s current condition. That’s where a car diagnostic tool like the Autel MD906Pro comes in.
How does the new Autel MD909 Pro stack up against other scanners in the MaxiDiag series? What upgrades does it bring, what are its standout features, and how does it compare to larger tablet-style diagnostic tools? And of course—how much does it cost? Let’s break it all down.
