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 ...

When working with electronic circuits, a multimeter is one of the most essential tools you can have. Multimeters help measure voltage, current, resistance, and continuity, making them indispensable ...

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 ...

Abstract: In general, measuring electronic circuits can only use ordinary measuring tools or manually. But as technology develops, measuring electrical circuits does not only use manual tools but can ...

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 current clamp is a measuring device especially useful for measuring large currents. In this article, we look at the first clamp meter launched by Fnirsi: the DMC-100. This is a competitively priced ...
