While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...

A Digital Multimeter (DMM) is a precision analog instrument used to measure AC and DC voltage, AC and DC current, capacitance, and resistance. Five system level blocks are common to bench DMM designs: ...

How many times have you poked around a circuit with a digital multimeter (DMM), read an AC voltage value, then gone on your merry way? Ever wonder if your meter is giving you peak value, average value ...

A precision voltage reference is useful in the lab for checking your multimeters. This post describes the construction of a poor man’s precision voltage reference. It is great for checking any ...
