launching a training mobile application that supports the
"Cycling Power" sensor via Bluetooth Low Energy. A descrip-
tion of this procedure can be found in the manual of the mobile
device.
If you are owner of the dual-sided TWiN2 powermeter:
Pairing via ANT+
The TWiN2 dual-sided power meter advertises itself in ANT +
communication as one device with an ID assigned to the left
arm. To add the TWiN2 measurement to the bike computer,
check what ANT + ID sensor on the left arm has, and then se-
lect it from the list of power sensors found by the bike com-
puter. Attention! The sensor on the right is not visible for bike
computers in ANT + communication. The sensor on the left in
ANT + communication emits data from both sensors (total L
+ R power).
Pairing via Bluetooth Low Energy
The TWiN2 sensor in Bluetooth Low Energy communication
will be announced as two independent devices with the follow-
ing names: "POWERCRANK L.XXXXX" and "POWERCRANK
R.XXXXX" where XXXXX is the 4 or 5 digit ANT + ID number.
Sensors L and R independently emit the measured power for
the corresponding leg. By default, "Zwift compatibility" is en-
abled for the TWiN2 measurement which causes the sensor on
the left arm announcing itself as "POWERCRANK L.XXXXX"
to emit the power value from both sensors (total power L + R).
6. Zero-offset calibration
How to perform the calibration:
• Start the device by turning the cranks several times.
• Remove both legs from the pedals and place the bike in the
riding position (fig. 7).
• Position the crank arms vertically as shown in (fig. 7) and
make sure that that no object is touching the pedals or the
crank arms.
• Activate the "Calibration" or "Zero-offset" function on the
cycle computer.
• Wait for a reply that will be displayed on the screen of the
cycling computer.
• If you have received an error, verify its meaning in the table
below and retry the calibration process.
