How to Wear the Device
Position the watch approximately one finger width up the arm from the wrist bone. If possible,
wear the watch on the non-dominant hand, as this improves the quality of the data. The watch
should fit tightly but comfortably around the wrist.
PPG Measurement
To take a PPG measurement, wear the watch on the wrist and make sure the skin has direct
contact with the LED/photodiodes at the center of the back of the watch.

ECG Measurement
To take an ECG measurement, wear the watch on the wrist and make sure the skin has direct
contact with electrodes 2 and 3. Then place a finger from the opposite hand on electrode 1. For
example, if the watch is worn on the left wrist, use a finger from the right hand.
Note: For best results on Windows 7, flash logging is recommended to avoid noise over the
USB cable.

Body Temperature Measurement
