6Power meter AnAtomyPOWER METER ANATOMYCadence Sensor RingCadence Sensor Ring LabelBattery CompartmentCrankarm Spider Serial Number/ANT+ IDLED
7INSTALLATIONINSTALLATIONMAGNET INSTALLATIONQuarq power meters measure cadence using a magnet, or if a magnet is not present, by using an accelerometer that is built into the power meter.Using a magnet is the best method for measuring cadence; it is accurate to +/- 1.5% regardless of environmental conditions. When properly installed, the magnet should be in line with the cadence sensors and within 2-8 mm of the sensor ring. If necessary, magnets may be stacked to achieve the proper distance to the sensor.NOTICEDo not allow the magnet to contact the power meter.If the magnet becomes dislodged or is removed, the built in accelerometer is automatically enabled.Using the accelerometer to measure cadence offers the convenience of not having to install a magnet. The accelerometer was specically developed for bikes that have limited options for magnet placement. While the magnet provides the most accurate cadence measurement, the accuracy of the accelerometer is excellent up to 160 rpm and in all environmental conditions except those that produce severe vibrations. It is easier to install the magnet when the cranks are not installed on the frame.BB Cup Mount Cable Guide Mount Adhesive Putty
8BB Cup Mount InstallatIonBB CUP MOUNT INSTALLATIONThe BB Cup Mount is only compatible with threaded bottom brackets. It does not work with frames that have bearings pressed into the bottom bracket (BB30, PF30, etc.). Frames using threaded bottom bracket adapters (ie. SRAM GXP30 BB Adapter) may use the BB Cup Mount if the mount is installed onto the threaded drive side bottom bracket cup.1. If necessary, remove the existing cranks and bottom bracket. 2. Slide the BB Cup Mount over the threads of the drive side bearing cup with the magnet facing away from the frame.3. Hold the magnet at the 9 o’clock position while the bottom bracket is tightened to the manufacturer’s recommended torque.4. Conrm the magnet is within 2-8 mm (1/16”-3/8”) of the sensor.2-8 mm(1/16”-3/8”)
9Cable Guide Mount installationCABLE GUIDE MOUNT INSTALLATIONThe Cable Guide Mount should only be used when the cable guide is fastened with a screw. If the cable guide is fastened with a rivet, use the Bottom Bracket Cup Mount or Adhesive Putty instead. NOTICEDo not allow the magnet to contact the power meter. When properly installed, the magnet should be in line with the cadence sensors and within 2-8 mm (1/16”-3/8”) of the sensors.1. Remove the existing cranks.2. Loosen the cable guide screw. It may be helpful to shift the front derailleur to the small chainring position, and the rear derailleur to the smallest cog. This will reduce the cable tension, and make it easier to slide the cable guide mount under the cable guide.3. Slide the mount under the cable guide. The guide can be installed with the magnet pointed down (as illustrated) or up.4. Reinstall the cranks.5. Tighten the cable guide screw.6. Conrm the magnet is within 2-8 mm (1/16”-3/8”) of the sensor.2-8 mm(1/16”-3/8”)
10Adhesive Putty instAllAtionADHESIVE PUTTY INSTALLATIONThe included adhesive putty will permanently attach the magnet to your frame. Other non-permanent attachment options include: hot glue, some epoxies, electrical tape, or similar adhesives.NOTICEDo not allow the magnet to contact the power meter. When properly installed, the magnet should be in line with the cadence sensors and within 2-8 mm (1/16”-3/8”) of the sensors. Depending on your frame, you may need to stack magnets to achieve this distance.1. Remove the existing cranks.2. Use the included sandpaper to gently scuff the frame where the magnet will be mounted. The center of the magnet should be positioned between 27.5 mm and 30 mm (1” - 1 1/8”) from the center of the bottom bracket.3. Clean the frame with the included alcohol pad prior to attaching the magnet. 4. Knead both colors of adhesive putty with your ngers until you have one consistent color.5. Place a 6 mm (1/4”) diameter ball of putty on the back of the magnet, and then press the magnet onto the frame. 6. Use a toothpick to carefully remove any excess putty before it dries. The putty will set up in about 10 minutes, and will cure in 1 hour.7. Reinstall the cranks.8. Conrm the magnet is within 2-8 mm (1/16”-3/8”) of the sensor.2110020 30 4034578692134130 1408921345mm/inchOFF ON ZERO100 1202134576

12PairingPAIRINGBefore pairing your power meter to a computer, make sure you are at least 10 meters (30 feet) from any other ANT+™ device. This will keep you from accidentally pairing to another person’s ANT+ device. To pair the power meter with an ANT+ computer, rst spin the crank backwards 2-3 times to wake the power meter and begin broadcasting ANT+ messages. The power meter will shut off after 10 minutes of inactivity.Follow the pairing instructions specic to your ANT+ computer.GARMIN® EDGE® 800Quick Tap On/O → tap the Dumbbell icon → Search“Power Meter Detected” will ash up on your screen when the units are paired.GARMIN EDGE 500Menu → Settings → Bike Settings → Bike 1 → ANT+Power → Search“Power Meter Detected” will ash up on your screen when the units are paired.GARMIN EDGE 510, 810Connections → tap the Dumbbell icon → SearchGARMIN EDGE 1000Drag Screen Down → Sensors → Add Sensors → Power“Power Meter Detected” will appear on your screen when the units are paired.
13ZeroingZEROINGThe power meter must be zeroed to compensate for environmental changes. The power meter can be zeroed two ways: Auto Zero and Manual Zero. When to perform the Zero procedureFor best results, you should perform the Manual Zero procedure before each ride. The Auto Zero procedure can be performed instead of a Manual Zero or if your computer cannot send a “Calibrate” command; if the temperature changes greatly during your ride; or if you are getting inaccurate data.Manual Zero The Manual Zero procedure should be performed before every ride with the rider off the bike and with the drive-side crank arm at 6 o’clock.The power meter may be zeroed manually by sending the “Calibrate” command from an ANT+™ compatible bike computer. The power meter will return the Zero Offset value (or “Current Calibration” on some computers) to the computer; however, not all ANT+ computers will display the value. The Zero Offset is typically between +/- 1000. Some units will always have a Zero Offset value outside of this range without any impact on performance. What is more important is that the pre- and post-ride Zero Offset values are within 50 points of each other. If the pre- and post-ride Zero Offset values frequently vary by more than 50, or if day-to-day values vary widely, please call Quarq customer service.When performing the Manual Zero procedure, put the drive side crank arm in the 6 o’clock position, keeping the cranks stationary with no force on the pedals. Follow the pairing instructions specic to your ANT+ computer to send the “Calibrate” command. The LED will ash one time when zeroing is complete.GARMIN® EDGE® 800Quick Tap On/O → tap the Dumbbell icon → CalibrateGARMIN® EDGE® 500Menu → Settings → Bike Settings → Bike 1 → Ant+Power → CalibrateGARMIN® EDGE® 510 & 810Connections → tap the Dumbbell icon → CalibrateGARMIN EDGE® 1000Drag Screen Down → Sensors → 'SENSOR NAME' → Sensor Detail → Calibrate
14ZEROING CONTINUEDZEROING CONTINUEDAuto Zero Spin the crank backwards for 4-5 complete revolutions. The LED will ash one time when zeroing is complete. The computer will not display the Zero Offset value. The Auto Zero procedure may be performed while coasting with the rider on the bike, stopped using one or both feet, or by hand with the rider off of the bike. Zero Offset StabilizationWith a new power meter or newly installed chainrings, the zero offset takes 2-3 rides to stabilize. During this time you should perform the Manual Zero procedure regularly to ensure accurate power readings. Short, hard efforts in both chainrings on your rst ride will speed up stabilization.
15CHAINRINGSCHAINRINGSCHAINRING INFORMATIONOn power meters with OmniCal™ you can swap chainrings without impacting accuracy� They do not need recalibration when you change chainrings or chainring sizes� Power meters with OmniCal™ only require re-calibration when moving from two chainrings to a single chainring, like moving to a Force CX 1 X-Sync chainring�XX1 power meters do not have OmniCal™� They are factory calibrated for 32T and 34T X-Sync chainrings� XX1 power meters require recalibration if you install a 36T or 38T X-Sync chainring�Re-calibration can be done using Qalvin, Quarq's diagonstics App�The zero offset will change whenever chainrings are removed and/or reinstalled� The zero offset will take 2-3 rides to stabilize� Recalibration is never required if you are replacing worn chainring(s) with new chainrings of the same make and mode�
