While LCR meters are readily available at reasonable cost, they do not measure the Q of an inductor. This circuit enables you to measure the Q of inductors with the aid of an RF signal generator. A ...

The analog DC ammeter with an actual full-scale value of 10 milliamperes in your transmitter that measures 1 ampere of plate current has failed and the only linear meter that fits in the same space ...

Applications such as amplifiers, audio systems and ultrasound require precise phase measurements. This application note shows how to create a simple, low-cost phase meter that provides close to 1% ...

I recently built a simple electromagnetic field (EMF) detector based on a code by Christian Figge that I found on the web. My design includes a 10-LED bar graph (from eBay), which I used to display ...

TruFlow meters from Nordson Corporation enable monitoring and control of material flow during all phases and line speeds of production for nonwovens, book and product assembly, as well as for ...
