4. Operating Instructions
Powering On/Off:
The PP5 power meter automatically activates when pedaling is detected and enters sleep mode after a period of inactivity to conserve battery.
Connecting to Cycling Computer/App:
The PP5 supports both ANT+ and Bluetooth Low Energy (BLE) protocols. To connect:
- Ensure the power meter is awake (pedal a few revolutions).
- On your cycling computer or smartphone app (e.g., Garmin, Wahoo, Zwift), navigate to the sensor pairing menu.
- Select to add a new power meter sensor. The PP5 should appear in the list of available devices.
- Select the PP5 and complete the pairing process.

Calibration:
For optimal accuracy, it is recommended to perform a zero-offset calibration before each ride, or if the bike has been moved or experienced significant temperature changes. Consult your cycling computer's manual for specific instructions on performing a zero-offset calibration for a power meter.
Understanding Power Data:
The PP5 provides various metrics to help analyze your cycling performance:
- Power (Watts): The amount of work you are doing.
- Cadence (RPM): Your pedaling revolutions per minute.
- Left/Right Balance: The power distribution between your left and right legs.
- Pedaling Smoothness: An indicator of how consistently you apply power throughout the pedal stroke.
