Auto Zero and Manual Zero.
When to perform the Zero procedure
For best results, you should perform the Manual Zero procedure before you start 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 feel that you are getting inaccurate
data.
Manual Zero
We recommend that the Manual Zero procedure be performed with the rider off of the bike.
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 +/- 500. 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.
