Calibrating power PODs and slope

Suunto Ambit2 S automatically calibrates your power POD when it finds the POD. You can also calibrate the power POD manually at any time during an exercise.

To manually calibrate a power POD:

1. While you are in a sport mode, keep Next pressed to access the options menu.
2. Stop pedaling and lift your feet off the pedals.
3. Scroll to Calibrate Power POD with Light Lock and select with Next.

Suunto Ambit2 S starts calibrating the POD and indicates if the calibration succeeded or failed. The bottom row of the display shows the current frequency used with the power POD. The previous frequency is shown in parentheses.

If your power POD has an auto zero feature, you can turn this on/off through your Suunto Ambit2 S.

To set auto zero on/off:

1. After the calibration is completed, press Start Stop.
2. Set auto zero On/Off with Light Lock and accept with Next.
3. Wait until the setting is completed.
4. Repeat procedure if setting fails or power POD is lost.

You can calibrate the slope for power PODs that use Crank Torque Frequency (CTF).

To calibrate the slope:

1. After the power POD calibration is complete, press Start Stop.
2. Set the correct value according to your power POD manual with Light Lock and accept with Next.
3. Wait until the setting is completed.
4. Repeat procedure if setting fails or power POD is lost.
