Zero Reset Procedure
The torque applied to the securing hardware can impart some strain into
the crank material that is easily accounted for by performing a zero reset
on the power meter. Any time the power meter is removed from the bike
and reinstalled, a zero reset should also be performed. Ambient temperature
shifts can also affect the zero reset to some extent. To ensure maximum
accuracy, it is advisable to zero reset (or "calibrate") before each ride.
When paired to a compatible head unit, the power meter and head unit are in
two-way communication and the head unit is able to send a command to the
power meter to perform a zero reset and in some cases, the resulting zero
reset value(s) will be sent back from the power meter to the display unit and
be shown on the screen. Please note the displayed zero reset value(s) will
NOT be zero, but rather a number that corresponds to the measurement taken
by the sensor. The head unit will also indicate if the procedure succeeded
or failed. This process may be referred to as zero reset, calibration, or zero
offset depending on the head unit manufacturer.
Although the process for performing a zero reset will vary depending on the
head unit manufacturer, it should roughly follow these general steps. Consult
1.
Rotate the power meter crank(s) one rotation to ensure the unit is awake.
Verify that the power meter has been paired to and is communicating
with the head unit.
2.
Position the cranks vertically (see page 5) with the bike in a stable
position. Note: See error code #32 in the troubleshooting section below.
3.
Access the settings function of the head unit.
4.
Select the power meter from the menu and select the "Calibrate" or
"Zero Reset" function.
5.
which should take a few seconds to complete.
6.
Compatible head units may show a success message featuring the
zero offset value(s) for one or both (Stages Power LR) sensors.
