Hi Harvey, I'm not sure if RLD_SENS = 0x2F will work either, it may simply cancel out your signal of interest. Typically, the RLD is used for common-mode cancellation when there is some separation between the placement of the RLD electrode and the ECG measurement electrodes (RA, LA, LL, etc.). Chief - R11 and C27 set the closed-loop bandwidth of the RLD amplifier. Limiting the bandwidth helps maintain stability as the RLD amplifier is driving several high-frequency poles from cable parasitics, etc, which are part of the larger feedback loop that encompases the patient. R13 is the protection resistor used if RLD is routed back into the chip and drives the patient through one of the measurement electrodes. See "Rerouting the Right Leg Drive Signal" section on page 50. If this feature is not used, R13 can be left uninstalled. Best regards,
