DC offset rising to the sky
Posted: Mon May 20, 2013 2:50 pm
Dear BioSemi support,
I would like to ask for your advice on an issue I had today. It happened that after putting in all electrodes, everything looked nice. But I could see DC offset levels slowly rising for all electrodes until eventually they got too high (this happened throughout a couple of minutes). I tried changing all cables (the 2 cables of 32 electrodes each and the CMS/DRL) and I also tried with a different amplifier. Nothing stopped this behavior.
So, after taking the CMS/DRL out and plugging it back in, everything nice again and slowly the offset increasing. Do you have some suggestion as to what might be causing this behavior or what I can do to fix it next time I come across it ?
If there are more details you would like me to provide, please let me know.
Best Regards,
Mihaela
