New eeg Device for arduino using Kicad

[stams007]

Hello and good day. i purchased some Passive Electrodes from olimex and i would like to know how to connect the female jack in the pcv im making.Cause i checked with polymeter and it seems the electrodes read through Ring (middle part). When i use continuity it beeps there and not in the Tip. So i would like to know how to connect the electrodes to the 2 Pins (2-3) of the AD620.

Thank you
