Eddy Current Probes

I have an old eddy current (single coil - absolute) probe that I found recently at my company. I don't have any information on the probe. I was wondering how I could find the operating frequency of this probe. What happens if I operate it at higher frequency and lower frequency?

Thanks

Re: Eddy Current Probes
Be carefull - lower frequency can burn the coil of probe
Use 2MHz as central frequency and using Sloted Standard (Hocking 29A029 for example) try to find out better response using "F" controls. In probe central frequency you will get Higher responce.

Re: Eddy Current Probes
I wouldn't select a frequency immediately.
Can you tell me if there are any markings on the probe ?
