It can look pretty intimidating-but we can help walk you through everything you need to know. ![]() Understanding How to Use the Multimeter Dial SettingsĪlmost every multimeter uses a large dial to set the mode. That extra precision has to do with the increased resolution afforded by the advanced digital components, error correction, and processing. Because the results are digital, a digital multimeter has the potential to be much more accurate and precise when taking measurements. For example, a digital multimeter includes internal electronics that include converters, comparators, encoders, and logic controllers. The dial on the display (which looks like a VU meter) reacts with magnetic fields created by changes in the electrical current detected by the device.Ī digital multimeter (DMM) gives you a digital readout but also offers additional functions. An analog multimeter measures voltage (volts), resistance (ohms), and current (amps). The difference between an analog multimeter and a digital multimeter comes down to the display and what they measure. In this article, let’s assume you want to use a multimeter. You can pick up a basic multimeter for less than $20, and they’re widely available. Every Pro uses a multimeter for troubleshooting, but even a homeowner benefits from the use of this tool at some point. How to Use a Multimeter for Testing Batteriesįirst things first, multimeters (voltmeters) typically work as analog devices.Understanding How to Use the Multimeter Dial Settings. ![]()
