Since the last update I'm having trouble to calibrate my quarq power meter. Please does anyone knows how to fix that ?

agalhardo are You sure that is it the result of the last fw update? What kind of Quarq is it ? Does it have bluetooth? if Yes, can You calibrate it via AXS app on your mobile? btw , if it is newer Quarq (Dzero, DFour or AXS), in the latest firmware for it (version #11) there is "magic-zero" feature which is autozeroing your powermeter by itself (autocalibration), dont need to manually zeroing on headunit (or via AXS app). If it older (so has no bluetooth only ANT+ ) then You should get an another headunit (different than 1030) and trying to zeroing with that, and You will see it is ok or not. If You have Quarq Rival spindle-based powermeter, that has also BT connection so You can try to zeroing it via AXS app (the Rival has no magiczero feature so You need to zeroing it before every ride)

I have the same Problem since Last update
