The specifications of the Adinstruments ECG setup are basically as those from Dr. Soctt Hardens (MD., PhD.) Sound Card ECG:

Dr. Scott Hardens (MD., PhD.) Sound Card ECG is only a (3 electrode) 1 lead ECG system

Gold standard for HR measurement is 3 lead ECG:

19.18 For runs on a treadmill at 4, 5, 6, 7, 8, and 9 mph at zero inclined, a 3 lead ECG is gold standard for HR measurement
