I am doing R&D and have been hit by a problem. I want to find the resonnce frequency to my heating coil without having to hook it up to the rest of my oven. I fall into the problem because I don't have the stray funds to buy a frequency generator. I heard that with capacitors and an oscilloscope that I could find my frequency.(adsbygoogle = window.adsbygoogle || []).push({});

I have tried to use an oscilloscope, the coil, and a 9volt. My results are varying from17.44MHZ to 35.71MHZ. The non-consistancy is what is frustrating me.

If anyone knows the backdoor way to test without a generator, the information would be greatly appreciated.
