Raw Data

[Udo]

Hi,
first a big big thank you for that amazing app!!!
second a question :

In the raw data the values are in µv, right. The range specified is 0 to 1682 as you mentioned in the manual.
In the books i read is alway said, that the range is between 5 and 100 µv that can be measured.
Is there a specific reason, why "your" range is so different?
Best regards
Udo

0 to 1682.815uV is the maximum detectable range of the physical electrodes on the device. The electrodes are just voltage meters, so their range is beyond that which can be generated by your brain.

Also, you may see spikes above 100uV for other reasons, such as EMG from blinking, or static discharge.

Thank you for the explanation. I see values at an average of 800 having amplitudes +/- 40.
So you think this is the result of disturbance by other electrical equipment?
Best regards

That sounds about normal. The better the contact you have with the skin and the less EMG you have, the lower your variance will be.
