Before attempting to calibrate the zero o set value of the power meter,
ensure that a working battery is in use. Rotate the power meter one revolu-
tion to ensure the power meter is awake and ready to communicate.
The left crank arm with power meter MUST be positioned straight down (6
o'clock position) and ensure there is no load on the pedals and the bike is
stable. See FIG 8 for a visual reference. If the left crank arm is not straight
down the reset procedure for zero o set will fail.
Although the process for calibrating the zero o set will vary depending on
the display manufacturer, it should roughly follow these general steps;
however, consult your display unit's manual for speci c steps:
1. Ensure the power meter has been paired to and is communicating with
the display unit.
2. Position the crank straight down (6 o'clock position) FG 8, and the bike is
stable.
Note: please see error code #32 in the troubleshooting section below.
The power meter sensor will determine if the crank is positioned in an
acceptable orientation during the zero reset process.
3. Access the settings function of the wireless display.
4. Select the power sensor (many times the power sensor is located within a
"BIKE" setting).
5. Select the "CALIBRATE" or "Zero" function.
6. Calibration of the zero o set will begin and take only a few seconds to
complete.
7. Upon completion the display will show a message indicating success or
failure of the procedure.
Calibration time out
When using a Garmin® display unit with the heart rate (HR) sensor enabled, it
is possible the calibration process will take too long and time out before
completion. To resolve this either turn o the HR sensor on your Garmin while
you calibrate your power meter (you can turn it back on once the power
meter is calibrated) or put the HR strap on and ensure it has been detected by
the display before you attempt to calibrate the zero o set.
