Heart Rate Monitor Tips
If you are noticing inaccurate
or erratic heart rate data, use the
following tips.
Make sure the heart rate monitor
is snug against your body.
Reapply water, saliva, or
electrode gel to the electrodes.
Clean the electrodes. Dirt and
sweat residue can interfere with
heart rate signals.
Wear a cotton shirt or wet your
shirt if suitable for your activity.
Synthetic fabrics that rub or flap
against the heart rate monitor
can create static electricity that
interferes with heart rate signals.
Move away from sources of
strong electromagnetic fields and
some 2.4 GHz wireless sensors,
