Extern electrodes

Dear all,

I’m using the Biosemi equipment for EEG acquisitions since few days but I have a problem with the extern electrodes’ signal. Sometimes, I have no signal and sometimes, I have a signal but very unstable.

I’ve contacted the Biosemi support which tell me to bundle the electrode wires of the extern electrodes with the CMS/DRL lead and all other electrode leads but I see no change.

Can someone help me?

Thank you very much in advance !
