NOTE : When J3 and J4 are set to 100x, you must use external electrodes via J12 instead of using the
on-board slider contacts. On-board slider contacts yield more noise due to the unsecure connection
with fingers. Noise in the first stage of instrumentation with higher amplification can easily results with
saturated output so you won’t be able to see the EKG output in the final amplification stage.
NOTE : MEG-EKG by default is configured to use the Flexis MM on-chip analogs. The option that uses
external INA is not functional by default.
