AD-box problem

[Nurhi]

Hi all;
ı have a problem about analyzing the EEG datas, it seems the system does not work properly, hence when I make measurements with 64 electrodes located and without the electrodes, the results of both situation are the same. I have checked my analyzing codes sevral times, they seem ok. Does this mean I couldn't do correct measurements? or could the system need to be fixed?
Has anybody met this before?

Thanks in advance.

Test the system with the electrodes in salt water as described in the manual, and discuss the results with BioSemi directly. An AD-box problem is very unlikely.
