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 ...

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.” ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

It's evident right in the name why a multimeter can be so handy — it measures multiple things, including voltage, current, and electric resistance. This makes it useful whether you're a professional ...

A specialized test gadget that tests continuity quantitatively in both AC and DC modes could prove to be an indispensible bench test instrument. This article describes such a continuity test set up, ...

How do you know if a resistor is correctly restricting the flow of electricity? Using a multimeter is an obvious answer. However, there is more to it than meets the eye. This article will explain what ...

The fruit of a collaboration with Labsphere, the 2500INT is a custom-designed integrating sphere optical head that facilitates direct optical measurement of laser diode output power when used with ...
