A Surprisingly Accurate Digital LC Meter
An inductance / capacitance meter by Phil Rice VK3BHR, Almost as published in Amateur Radio magazine, April 2004.
A Surprisingly Accurate Digital LC Meter
“The AADE web site gave details of how their design worked and a circuit diagram. This led me to propose a design using their oscillator, but in a slightly different way. Like theirs, mine would measure the free running frequency of an LC oscillator, then successively apply a known capacitance then the unknown inductor (or capacitor).”
Der hier vorgestellte Nachbau des LC-Meter von VK3BHR, Phil Rice, verwendet einen PIC 16F84 und eine Punktmatrixanzeige. Der Messbereich geht in etwa von 0 bis 10 mH für Induktivitäten und von etwa 0 bis 100 nF für Kapazitäten.
