Getting Your FTP Estimate The device uses your user profile information from the initial setup to estimate your functional threshold power (FTP). For a more accurate FTP value, you can conduct an FTP test using a paired power meter and heart rate monitor. Select > My Stats > Power > FTP . Your FTP estimate appears as a value measured in watts per kilogram, your power output in watts, and a position on the color gauge. For more information, see the appendix ( FTP Ratings , page 84 ). Automatically Calculating FTP Before the device can calculate your functional threshold power (FTP), you must have a paired power meter and heart rate monitor ( Pairing Your Wireless Sensors , page 49 ).
The estimate may seem inaccurate at first. The device requires a few rides to learn about your cycling performance. 1 Select > My Stats > Power > FTP > > Auto Detect FTP . My Stats Edge® 540 Owner's Manual 21 Purple Superior Blue Excellent Green Good Orange Fair Red Untrained
