The resistance of the diode cannot be measured with the normal ohmmeter on a DMM because the voltage used may not be high enough to bias the diode. DMM’s often have a diode testing mode that supplies ...

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, ...

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 ...

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 ...
