I originally used them with an 800 and the "setting of angles" is done by ensuring that the batteries have been removed for >10secs to clear the memory of the pods, then spinning up to >90rpm for a minute or so, levelling the cranks so both pods are downwards and performing a static calibration.
you are then supposed to do a dynamic calibration performed by back pedalling smoothly over 30rpm for 8-10 revs until a message pops up saying "Power Sensor Calibrated”
apparently this supposed to be done every ride, although the battery out bit can probably be left to when moving the pedals between bikes...
Ace, thanks Sainos. That's really helpful. I've done all that when shifting the unit around except the battery removal.... i presume it's been under-reading all this time then :-)
yes, id presume that too, I went through a phase where I didn't remove the batteries and it was under reading chronically, probably to about the tune of 60w based on a time trial I did at the time. was tearing my hair out trying to work out what had happened to my legs!
