Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

It’s remarkable how tiny electronics have become. Heaven knows what an old-timer whose experience started with tubes must think, to go from solder tags to SMD in a lifetime is some journey. Even the ...

Digital multimeters have replaced traditional analog meters long back. It offers better accuracy, reliability, and better handling of impedance. It is a versatile device in the truest sense. You can ...

Performing single-point pass/fail DC tests on packaged diodes is critical to ensure compliance with manufacturers’ specifications and weed out defective devices before they are shipped. Most types of ...

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.” ...

The Keithley System 25, a fully customizable test system for the light-current-voltage (LIV) characterization of laser diodes and assembled laser-diode modules (LDMs), lets users choose only the ...

From Leatherman multitools to oscilloscopes with built-in signal generators and protocol analyzers, there seems no end to tools with multiple personalities. Everybody loves multitaskers because they ...
