Page 4: Important Notes
The device is not waterproof as by design it has pressure measurement holes. aerosensor should be removed in wet conditions. If you think it will rain whilst you are out riding or the road may be wet in places then take a 3mm hex key wit you so you can remove the device and put it in your jersey pocket for the rest of your ride. -

• aerosensor should be level - use a horizontal object to the side of the bike (like floor markings), and visually align the bottom of Aerosensor with the horizontal line. An example is shown below, where a horizontal line on the wall is used. Note that the device is tolerant to pitch misalignment within +/-5°. -

Duck tape along length of tapeswitch Direction of travel aerodrome listens for aerosensor and the LED flashes when it receives data. It is only able to transmit the lap trigger when this is happening. Make sure aerodrome is situated in a position where it can receive data from aerosensor when bike is at or just past the Tapeswitch. - Page 12 ACS Instructions V7.0...

1. The aerosensor ACS CIQ app can be download from the Garmin Connect IQ website: https://apps.garmin.com/ 2. Simply search for “aerosensor” and the app will come up, or use this link: https://apps.garmin.com/en-US/apps/0170243b-0384-4072-9e85-57030e4949a6 3. Install to the Garmin head unit as per the instructions on the CIQ app website. -

A typical value would be 0.98, i.e. 2% drivetrain loss. 5. CTF calibration offset: Used for CTF power meters. 6. Time av period: This is the time period used by aerosensor to average the CdA value, default is 30 seconds. - Page 16 The device automatically creates laps for each CdA measurement period. Editing Parameters: The aerosensor device must be turned on and connected before taking the following steps. 1. Go to Menu-> aerosensor Settings-> aerosensor Parameters. 2. Ensure that the parameters have been received (“20 parameters received” under “Get Layout”...

Page 17: Velodrome Testing - Track Layout
Velodrome testing - Track layout When aerosensor is in track calculation mode it uses lap distance and speed to calculate lean angle to compensate for centre of gravity location. This only works when aerodrome is being used. A typical track layout is shown below, of which you can input the track measurements by editing parameters directly in the CIQ app. -
Page 18: Velodrome Testing - Calculation Mode
Screen sequence shown below. Velodrome testing - Calculation mode At the velodrome aerosensor can ignore the barometer, since elevation is roughly constant, and should use the track map. If the track map is not known, or aerodrome is not available, you can use a trackless mode. -

Lap 6 1.03 Lap 7 1.14 The average of these values is 1.09. 1.09 x 1.18 = 1.29. You should go into aerosensor settings -> parameters and enter this new value. This value varies a little with your body position so for accurate CdA data periodically repeat this process. -
Page 24: Quick Start Checklist
✓ Make sure aerodrome is situated in a position where it can receive data from aerosensor when bike is at or just past the tapeswitch. It is normally best to position 1-2m downstream of where the lap trigger is placed. - Page 25 ✓ For road testing we recommend out and back testing (between 500m and 1000m ideally) per configuration. ✓ For track testing we recommend 6-8 laps per configuration. The more laps the better for accuracy. ✓ Always start and end a test with the same configuration to be sure of repeatability. ACS Instructions V7.0...
