Re: The F-Scan2 - a critical evaluation

Stefan,

I have posted 3 DIRP data sets in an xls file at
http://www.tookworks.com/fscan/dirpdata.xls

These scans are just what I happened to have on this PC- random samples, if you will. You'll notice that the three test subjects have very individual profiles. IT has a very flat CV line, and only a few readings that might be called spikes. Could be just noise. IS has a CV line that follows the groups of peaks. CB has a fairly smooth CV curve, with pretty obvious peaks. If I remember correctly, when the DIRPS were done, CB and IS had active cold or flu bugs. IT was feeling run down, but otherwise OK.

Personally, I think that the CV line is enlightening in IS's case. I think that it shows a broad spectrum disturbance, that the FSCAN picked up as a series of intermittent spikes, which goes back to my previous post. Thing is, the delta was 1000, so that's a *very* broad bump.

Another peeve of mine with the unit is the initial spike. The first DIRP you do when the unit is first turned on will almost always show a huge spike for the first frequency. I believe that this is due to a software issue- the first reading has no prior reading to compare itself with, and so represents a big jump from zero. That could be fixed in firmare, by having the machine test the first frequency twice, or introduce a 'prep frequency' before the initial DIRP frequency. All of which is to say that the machine is not without its problems, but I stand by my results.

Going back to why it doesn't work for you- I've been thinking about it, and I'm having a hard time believing the results you're seeing are possible without something being wrong with the unit. Either in the ADC, or possibly the eeprom. Do you have the latest firmware update? Before jumping to 'quantum suggestivity', I'd want to rule out anything else. Unfortunately, the typical "test, replace, retest" A to B methodology would require two units. I had thought that perhaps your own personal body chemistry was producing an inductance, or a damping field effect, but that would likely still give a different profile than scanning a resistor network. So I'm stumped. Regarding the person I was unsuccessful with, I should add that I think the problem there was that the CVs were too low to allow a good reading. Typically 1 or 2, and nothing we tried got it higher. I did get a DIRP result that looked like a noise floor, but nothing useful- could have been reading the lights in the room for all I know.
