Zero Reset - Stages cycling Power Manual Del Usuario

Zero Reset

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 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.
Manual Zero
When paired to a Stages console or 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 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 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.
To manually calibrate the zero offset of the power meter:
• Rotate the power meter one revolution to ensure the power meter
is awake and communicating with the Stages console or head
unit.
• Position the cranks vertically (FIG. 2).
• Follow the instructions supplied with Stages display console or
other display unit being used with the power meter.
Auto-Zero
The power meter will automatically update the zero offset value after
a period of inactivity. No action is required to enable this function,
which will automatically update the zero offset value between uses
and ensure the power meter is functioning at a high level of accuracy.
