Why does it take so long for the heart rate to be
measured?
It takes approximately 8 seconds to measure the
heart rate, the longer it takes to acquire the signal
from the sensor the more accurate the testing
results will be.
Why does the tracker need to be snug against my
wrist when measuring heart rate?
If there is space between your wrist and the tracker
the light will reflect on the sensor and the result will
not be as accurate.
