HOW TO PAIR THE CONSOLE continued
8. Complete the pairing process
If the pairing process
is successful, the word
PAIRED will appear in
the message banner.
After several seconds
ZERO RESET will appear.
Go to page 24.
If the pairing process
fails, the word FAILED
will appear in the
message banner.
Go to
step 10.
9. Pairing to a power meter without an ANT+ ID
label
If an ANT+ ID label is not present on the power
meter, it is still possible to pair it to a console.
Repeat Steps 6 - 8, and enter all zeros as the ANT+
ID number.
IMPORTANT: The console will attempt to pair
to any power meter that is awake and trans-
mitting. Ensure that all other power meters
within a close range are not awake and trans-
mitting. If the zero reset process (see page 24)
is successful, verify that the correct power
meter is paired by riding the bike in the WARM
UP mode (see page 12) and pedaling the
power meter above 20 rpm. If the power
meter is paired, a cadence and power should
appear on the console.
10. Troubleshoot the pairing process if necessary.
If the pairing process fails, follow these steps:
a. Make sure that fresh batteries are installed in
the sensor.
b. Spin the power meter or shake it if it is not
assembled on the bike to make sure it is
awake.
c. Place the power meter next to the console, so
that they are side by side.
d. Make sure that no other ANT+ devices in the
area are active. Pair only one console and one
power meter at a time.
e. See steps 3 to 6 starting on page 21 and
repeat the pairing process.
ZERO RESET CALIBRATION
Zero offset calibration is an important feature that
resets the zero offset value for the power meter sensors.
There are physical and environmental conditions that
may affect the zero offset value and there are methods
both manual and automatic that will adjust this value to
accommodate for the changing physical and environ-
mental condition.
The zero offset of the power meter is essentially the
sensor reading or values measured when the power
meter has no pedaling load (torque) applied. The act of
calibrating the zero offset causes the power meter to
measure the value at zero load and then records this
value as the baseline for power measurement. Loads
applied while pedaling will then be measured as torque
and used by the sensor to determine power in Watts.
The zero offset value can be affected by the installation
of the crank arm and the tightening of the securing
hardware. The torque applied to the securing hardware
can impart some strain into the crank material that is
easily accounted for by manually calibrating the zero
offset.
Any time the power meter is removed from the bike and
reinstalled the zero offset should be calibrated.
