ADS1298ECGFE-PDK: Reading sEMG signals from forearm

Part Number: ADS1298ECGFE-PDK
Other Parts Discussed in Thread: ADS1298

We have the Development kit and are trying to get the sEMG signals from single lead (three electrode negative, positive and Ref), but are unable to get meaningful signals. Any idea on how to connect the electrodes and jumper settings? We are using normal Gel electrodes one cm in diameter, 15mm apart on the forearm.

Finally we would be trying with Fabric  (electric conductive printed) electrodes to get the sEMG readings.
