Hey William,thanks for including them Yes I tried light, medium and hard tightening on the scalp. In fact when I tight them (when they start hurting quite a bit), the signal goes railed. I loose the tightening a bit and sometimes the inconsiste…

Hi William, I attached the electro-cap today and this is what I get, as expected, a clear signal.on all channels. Contact email haven't replied to me yet. If you have any more ideas in the meantime, please do let me know. I will update if they …

Thanks re:ohms. Understood will triple check on Friday. The electrodes come pre-assembled, you just screw them on the headset. I will tighten all the electrodes screws just in case. The O1 and O2 are inconsistent (check 1st screenshot). Sometime…

Ear clip same as the other electrodes, stable at 01.7 (with 200 Ohm setting). Just for my future reference are these values within acceptable range ? Yes I did. However it would be very unlucky to have eight electrodes that need wiggling/screw tig…

Hi William, I have tested 3 of the electrodes and showing a stable 01.7 on each one with (200 Ohm setting). .With a 2K Ohm setting it shows a stable .001. Is that within acceptable limits? Electronics aren't my stronghold. If these are wit…

Hey William,nice to speak to you again. Thanks for your prompt replies as always. I have just tried swapping SRB2 with the BIAS, same thing. I have tried changing the wires, but same result. Let me show you with some screenshots: Screensho…

that was my thought exactly... how was he able to get a 80uV on all A1 referenced channels... Did not know re:ADS1299 used in clinical equipment. Thanks. They must have some internal circuitry different then ours to be able to capture that sig…

I understand. I will make an assumption in my paper that clinical equipment might be more targeted to capture this artefact; at least from my findings. I stand to be corrected... The artefact was showing only on T3 and T4 since that was on bipolar…

Hi William,thanks once again for your prompt replies. Yes I though so as well re:article, but I have read so many books lately, I get mixed up who said what I think that those where using clinical EEG equipment, which would differ from our …

Hi William,many thanks for your reply. Yes you are right re:question title; I should have explained it better. Let me give you a few links: http://s32.postimg.org/jnahphp45/image.jpg (screenshot from book) https://www.scribd.com/doc…
