I am an industrial designer (little experience with electronics) trying to modify one of the AD8232 chip configurations. The AD8232 is a Single-Lead, Heart Rate Monitor Front End. In the datasheet, page 24 there is an exercise to measure heart rate signal at your hands with steel electrodes. This is the one (see image below) I would like to modify to get a good signal from steel electrodes, but without the right leg electrode.
I am working on a breadboard using a breakout for the AD8232. So far I do not get good results, I tried to use a configuration like can be seen below.
I need help with the configuration and setup, perhaps there are better ways to achieve the end result, I am open to ideas. Thanks.
