CHAPTER 2: JOULE GPS OVERVIEW & SETUP USER The Joule GPS allows sharing of the same device with multiple users (i.e. Rachel, Jim, Bob). Each user can have multiple bikes (e.g. TT bike, Road bike, MTB); each bike can have multiple sensors associated with it (e.g. -
Page 9: Sensor And Pairing
CHAPTER 2: JOULE GPS OVERVIEW & SETUP SENSORS & PAIRING Pairing is a term used to describe the association of your Joule GPS with a particular sensor that is broadcasting an ANT+ signal (e.g. a PowerTap hub, a Heart Rate strap, a remote cadence sensor, a remote speed sensor, etc.). -

Page 19: Sensor Details
Power If your power meter is a hub-based power meter, like a PowerTap, the wheel circumference can be entered here. The default wheel size of 2096mm represents a 700x23 wheel. Ignore circumference if your power meter is not hub-based. Auto Zero and Manual Zero options refer to calibration and are discussed in the next pages. -
Page 20: Calibration
TIP: The accuracy of any power meter is dependant on many variables, especially temperature. Fluxuations in temperature affect the internal strain guages, which affects the reported torque value (power is calculated from torque). The PowerTap Auto Zero feature continually adjusts the calibration of your device, compensating, in real time, for environmental factors like temperature, assuring that you have the most accurate power data throughout your ride. -
Page 21: Calibration
The calibration delta number does not correspond to a Watt value. It is there to simply assist visually during the action of increasing or decreasing the RU Watt value. Reset Reset to Default will reset all values to the factory default calibration. Joule GPS User Guide page 21... -

Compass calibration, etc. Waypoints assist with remembering and navigating to a particular location. Routes allow you to follow a particular predefined path. Waypoints can be created directly on the Joule GPS and stored on the Joule or in the PowerTap PowerAgent software application (available on both Mac and PC). Routes can be created from previous rides in PowerAgent and uploaded to the Joule. -
Page 23: Waypoints
WAYPOINTS For the purposes of the Joule GPS, waypoints are single specific locations on earth. Your home can be a waypoint. Your favorite trail head or cafe can be a waypoint. The Joule GPS can create, delete, select, and store waypoints. Each waypoint you create is stored on the device. -

CHAPTER 5: NAVIGATION COMPASS The Joule GPS contains a magnetic compass. The arrow near the right side of the Title bar on the dashboard points North, regardless of your direction of travel. It is good practice to calibrate the compass upon receipt of the device as well as after each firmware upgrade. -
Page 29: History Reports
HISTORY REPORTS The Joule GPS can create and display reports comparing one of your rides to the average of what you have done over a previous time frame. History reports by the last ride or any selected ride are compiled and compared to averages over 2 weeks, 4 weeks, 8 weeks, 6 months or 12 months prior to the selected ride. - Page 30 Note: Total view is the total values achieved for ZERO 0:11:57 0:08:14 WATTS each report metric over the average of two ZERO weeks, four weeks, etc. WATTS Joule GPS User Guide page 30...

Page 32: Workouts
TRAINING with PowerBeam PRO using Scripted WORKOUTS Workouts for the PowerBeam Pro can be imported to the Joule GPS from Power Agent. Within this “scripted” workout, resistance can be based on target slope (mimicking the resistance of a specific grade or incline), target power (a specific resistance value in terms of watts), power range (resistance within a range of wattage values) or power zone (a... -
