9.2. INSTALLATION
How often do I need to calibrate my ROTOR Inspider?
To ensure accurate measurement, it is necessary
to correctly calibrate (zero-offset) the power meter.
It is not necessary to zero-offset your power meter
before every ride, but it is convenient to do it every
week or two. It must be calibrated when:
-Power meter is installed on the bicycle
-Chainrings are installed or changed.
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.
ROTOR's INpower technology requires these two
calibration steps 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 power meters 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 power meter using either your
head unit, the U s e r S o f t w a r e , which you can find and
download for free from ROTOR's website, or the
ROTOR Power app for smartphones.
