Setting the Zero-offset before every ride is recommended to ensure the most accurate data.
The Zero-offset can be compared to zeroing a bathroom scale before weighing yourself; the
scale must start at 0 to measure an accurate weight.
From the Real-Time screen press MODE and SET simultaneously to enter the Zero-offset
mode. You will see two numbers; the top number is the current offset of the PowerMeter
and the lower number shows the previously stored offset. Hit SET once and the lower num-
ber will update to store the current offset. You have successfully completed the Zero-offset.
The Zero-offset is affected by temperature and humidity and can change slightly from day
to day and during a ride. The SRM PowerMeter has the ability to automatically update the
Zero-offset to account for these changes. The "Auto" function is activated when the word
Auto appears in the Zero-offset screen, this is the default setting in the PowerControl. A
speed sensor must be installed and transmitting in order for the Auto Zero-offset to func-
tion.
Altitude can be adjusted from the Zero-offset screen by pressing MODE. Use the PRO and
SET button to view or adjust elevation.
