Hi Paul,
You are right, I pinged the coil without resistance first but I didn't think I
saved it. However, I was pushing the buttons trying to get the file format
right and I bet I saved the first no resistance case. I thought I was pretty
careful during the run but setup was sort of interesting. So the files are
shifted as you suspect ;-)
I have to go to the Tesla coil meeting tonight but let me know if you want
anything run again like with a different time base. I also took single raw
captures instead of averaging over 16. Looks like it is going great!!
Cheers,
Terry
