Troubleshooting
Symptom
The value in the force preview
after calibrating under load is
not within the range of ±3 N
of the confirmation number of
calibration weight.
Crank length setting fails
The torque value does not
appear correctly when paired
to a different company's
cyclocomputer while in the
power meter mode.
The power value is not correct. The calibration may not have
The vector chart is rotating.
The left and right sides of the

Cause
The zero point calibration was
not done correctly.
Or, the zero point is incorrect.
Do both calibrations (tangential
and radial).
The angle of the crank during
calibration was wrong.
Something is wrong with the
strain gauge unit.
The sensor and Cyclocomputer
pairings are not stable.
The sensors' batteries are
dead.
The crank length is not set
correctly.
The calibration may not have
been done correctly.
been done correctly.
The zero point is incorrect.
This is a problem with either
the left or right sensor.
The magnet rings are not
installed correctly.
The BB was not correctly press
fitted into the frame when the
optional specialized BB was
installed.
The calibration may not have
been done correctly.

Solution
Dealer
Correctly calibrate the zero point.
Calibrate a high accuracy zero point
and calibrate both the tangential
direction and radial direction for the left
and right sensors.
If you do not calibrate both, the correct
value will not appear.
Set the crank at the specified angle
and then do the calibration.
The calibration cannot be done
correctly if the angle shifts.
If you want to re-install the strain
gauge unit, you need a new strain
gauge unit. Please visit our website.
Information may not be sent correctly
to the sensor depending on the radio
wave environment and the distance
between the Cyclocomputer and the
sensor. Stop the crank length setting
and move the Cyclocomputer closer
to the sensor or do the setting again
in a location with a better radio wave
environment.
Replace them with new batteries.
Information may not be transmitting to
the sensor correctly if the batteries are
depleted.
Change the left and right sensors to
the pedaling mode, and set the crank
length.
Change the left and right sensors
to the pedaling mode, and correctly
calibrate the zero point and do a
calibration under load.
Check the calibration (page 45). If the
calibration has shifted, change the
left and right sensors to the pedaling
mode, and correctly calibrate the zero
point and do a calibration under load.
Please visit our website.
Check that the left and right magnet
rings are correctly installed.
Also, check that the markers for
the left and right magnet rings are
perpendicular to the ground.
If the magnet rings are not installed
correctly, they may not operate
correctly.
Check that the frame and BB are
compatible.
Also, check if the BB was correctly
press fitted.
Depending on the type of frame, the
BB may rotate. If there is a gap, use
commercially available shim tape or
something to pressure fit on the BB.
Calibration may need to be done again
to ensure it is done correctly.
Check the values in the force preview
for when a force is applied and when it
is not applied.
