ECG Two Electrode Mode

[GkekasK]

Hello Sparkfun-team,

I purchased the "SparkFun Single Lead Heart Rate Monitor - AD8232" and I want to use the "two electrode mode" as mentioned in the datasheet in the following captions "Right Leg Drive Amplifier", "AC Leads Off Detection" and "Heart Rate Measurement Next to the Heart". How can I activate this mode? How can I extract the RL/RLD Pin in order to use only the RA and LA Pin?

Thank you very much for you help and time in advance

Best regards

Kosta

I have the same problem.
After modifying the resistors on the purchased Sparkfu AD8232 module by swapping R17 with R18 and R19 with R20, as per the datasheet recommendations, I used an oscilloscope to observe the output. However, when measuring with two electrodes, I am still unable to see the ECG waveform.
