What’s a DMM?

Multimeters. They’ve been described as a modern-day tape measure. But what exactly is a digital multimeter (DMM) and what can you do with it? How do you make measurements safely? What features do you need? What is the easiest way to get the most out of your meter? Which meter is best suited to the environment you’re working in?

Technology is rapidly changing our world. Electrical and electronic circuitry seems to permeate everything, and continues to get more complex and smaller in size. The communication industry booms with cell phones and pagers, and Internet connections have put more pressure on the electronics technician. Servicing, repairing, and installing this complex equipment in these environments requires diagnostic tools that provide accurate information.

So what EXACTLY is a DMM? A DMM is simply an electronic tape measure for making electrical measurements. It may have any number of special features, but mainly a DMM measures volts, ohms, and amperes. DMMs measure faster, more efficiently and with greater accuracy, almost any job in any industry. The three watch words when selecting your DMM are SAFETY, QUALITY and PERFORMANCE. Fluke models include handheld troubleshooters to ultra smart instruments packed with features, including the ability to log and graph data, as well as high-precision bench units.


Choosing your DMM
