Hi,

Below, you find a description of the problem and my procedure. My question is twofold:

1. Might the extreme decrease of skin conductance be a result of using the wrong gel? I got it from a pharmacy according to a receipe from a seminal work on GSR measurement (I don't have the title at hand ...

Dear Coen,

I believe that you mean 0.625 milliSiemens instead of microSiemens.

You mention that the smallest unit that can be measured (as I underrstand this is the implication of the LSB) is 31.25 nanoSiemens (nS). In my understanding that makes 20000 units = 20000*31.25 nS = 625000 nS = 625 ...

Thanks for the quick reply. I will try the two bucket test as you suggest.

Best regards,
Christian

Hi,

We purchased a second 32 electrode set two years after we bought our old one. Using both to measure with 64 electrodes (in saline solution) results in 2 clearly distinguishable groups of electrode signals on the ActiveView screen. The impression is that the amplitudes are larger for the new set ...
