   Pass/Fail Criteria:

   Pass: If the heart rate monitor is successfully able to detect the pulse generated by the MCU to an accuracy of ±2-3 bpm for each target rate.

   Fail: If the heart rate monitor is unable to detect the pulse generated by the MCU or detects the pulse to an accuracy outside of ±2-3 bpm for each target rate.
