The pressure wave calibration signal is a single, exactly repeating fing

is 1295 mV (129.5 mmHg), diastolic is 710 mV (71 mmHg), pulse
interval is 930 ms (exact) and calibrated heart rate is (60 x 1000 / 930)
= 64.5 BPM. For Finometer® Model-2, 1000 mV has to correspond to
100 mmHg. Thus S/D is 129.5/71 mmHg.
