Channels surface

Post by neuropacabra » Mon Nov 28, 2016 12:59 pm

Hello,

I would like to ask about Biosemi channels surface. I have already send them to waranty service and service replaced both CMS and DRL channels. After couple of weeks problem of all channels appeared. I am facing the problem that nearly all of my channels show periodical and harmonical signal (e.g., sinusoidals) and it doesn't react for any muscle or ocular artifacts. Just showing sinusoadals all the time. My question is that if I have CMS channel surface placed with some corosion (black spots on AgCl surface) I guess it would help me to pick a rubber and clean the surface to check if electrodes are ok or not. It is save to do so?

Thank you for your answer.

Michael

Start with testing the electrodes in water as described on http://www.biosemi.com/faq/check_electrodes.htm

Best regards, Coen (BioSemi)
