To edit the circumference, press and hold the right button until you see OK. The
digit you are editing will be flashing, and short presses of the left and right
buttons will cause the value to increase or decrease.
When the digit is set how you like it, then press and hold the right button to save
this and move over to the next digit. If you accidentally saved the wrong number,
you can press and hold the left button to go back to the previous digit.
Once the last digit is entered, the new value will be saved and you will be back to
navigating the speedometer setup menu.
6.2.3 Set Your Pole Count
The Cycle Analyst also needs to know how many
times the speed signal will toggle up and down with
each wheel rotation. With a CA3-DP device using a
direct drive motor this will be the number of magnetic pole pairs in the hub.
For geared hub motors that have an internal speed sensor, the #poles should be
set to the number of speed pulses on each turn of the wheel. Bafang and many
other geared motor manufacturers seem to have standardized on 6 pulse internal
speed sensors. If in doubt, simply count the number of times the 'P' arrow toggles
when the wheel is turned one revolution.
