Contact Heart Rate
chapter Two: Riding Your Bike
Contact
Heart Rate
(CHR)
The contact heart rate system lets you monitor your heart rate
without wearing a strap.
Gently grasp the contact heart
rate pads as shown below.
When the system detects your
hands, the heart rate LED
will flash in time with your
heart beat. During this time,
the system is analyzing and
locking in your heart rate.
Within about 10 seconds,
your digital heart rate in beats
per minute (bpm) should be
displayed.
A Note on CHR Accuracy
CHR monitoring may be a
bit less accurate than a chest
strap, since the heart rate
signals are much stronger at
the chest.
The ES9.0 bike uses the most
advanced CHR system avail-
able. It converts your heart
rate waveform to a digital
signal, then analyzes the digi-
tized waveform to pick out the
electrocardiogram shape and
thus the heart rate.
About 5% of the population
cannot be picked up by any
CHR system. This is because
their heart is positioned in a
more up-and-down manner
in their chest, as opposed to
leaning over to one side.
