Common Mistakes to Avoid

1. Ignoring Temperature Changes

Reason: Power meters are sensitive to temperature fluctuations. Readings can be significantly affected by temperature changes, leading to inaccurate power data.
Solution: Ensure your power meter is properly temperature compensated, either through automated calibration or by using a temperature-compensating factor provided by the manufacturer.

2. Failing to Follow Manufacturer Instructions

Reason: Each power meter model has specific calibration procedures and recommendations. Deviation from these instructions can lead to incorrect calibration and potentially damage the device.
Solution: Carefully read and follow the manufacturer's instructions for your specific power meter model before attempting any calibration.

FAQs

How often should I calibrate my bicycle power meter?
Most manufacturers recommend calibrating your power meter every 2-4 weeks, or after significant changes in temperature or after a crash. However, it's a good practice to check your calibration regularly and calibrate if you suspect readings are off.
What if I don't have a calibration tool or the device's instructions are unclear?
Contact your power meter's manufacturer directly. They'll likely have detailed instructions, videos, or even troubleshooting support available on their website or through customer service. In some cases, a local bike shop specializing in power meters can also assist with calibration.
