Digital Multimeter FAQs

What is a digital multimeter?

A digital multimeter measures electrical stimuli, including voltage, current, and resistance. It’s a diagnostic tool used by technicians and electrical engineers daily and combines the features of a voltmeter, ammeter, and ohmmeter.

How does a digital multimeter work?

Digital multimeters attach to probes, leads, or clamps, which are connected to an electronic device. The digital multimeter will then measure the device’s voltage, current, or resistance and use an analog to digital converter to present a value on the display.

How do I choose a digital multimeter?

When it comes to choosing a digital multimeter, there are a number of factors to consider, starting with where you will be using it. You’ll also want to look at accuracy, speed, and the number of channels needed to complete your job. 

How do you use a digital multimeter?

A digital multimeter is very easy to use. When using a benchtop DMM, you select the correct measurement mode, then attach probes, clamps, or leads to both the DMM and the device under test to make a measurement.
