Yes, the common electrode on the cap was gelled and prepped, and both earclips were connected.

Dear Ph.D., Common electrode is already on the cap. And two earclips has to be connected to A1 and A2. Best regards, AlexanderAfter applying a 19-channel Electrocap to a client and starting to record, all of the channels appeared identical, and were unresponsive to the usual sources of artifact. However, the impedances were different.A friend suggested this could be a problem with the ground electrode. Plugging one of the earclip electrodes directly into one of the two ground sockets on the Mitsar didn't help-- presumably because the ground from the cap continued to have the same problem. However, I don't understand the nature of this problem.Any ideas about whether this a cap problem? a ground electrode problem? or, a software (e.g., end-user-ignorance) problem?Thanks!
