9.2. INSTALLATION
How often do I need to calibrate my ROTOR
2INpower?
To assure accurate measurement, it is necessary
to correctly calibrate the cranks. It is not
necessary to calibrate your 2INpower before
every ride, but it must be calibrated when:
-Power meter is installed on the bicycle
-Pedals are installed or changed
-Chainrings are installed, requiring the cranks to
be disassembled.
Calibration is not required after charging the
battery.
Calibrating a second time is recommended after
30 hours of riding.
Read the user manual carefully to successfully
complete the calibration process.
Why do I have to calibrate twice?
The calibration process requires pressing the
calibration button twice on your head unit.
Inpower technology requires this second
calibration step because not only force has to be
calibrated, but angle too.
It is very important that you follow the steps
described in the user manual for correct
calibration. This assures an accurate power
measurement.
What are the calibration values?
ROTOR 2INpower requires angle and force
calibration. After the calibration button is pressed
the first time, you must see a value of 1000 on
your device's screen. After the calibration button
is pressed a second time, the screen's value must
be between +/-200. This second calibration value
is specific to each power meter.
If I have doubts that I've correctly calibrated my
power meter.
Read the user manual carefully and calibrate the
cranks as explained.
If you have doubts about correct calibration,
repeat the entire calibration process and
compare the two values obtained in the last step
of each process. Variations of +/-5 units are normal.
You can calibrate your cranks using either your head
unit or the User Software, which can be downloaded
for free from ROTOR's website. Read the User Software
manual for information about how to calibrate with it.
