I recently installed the magnetless speed and cadence sensors on my new bike. I could pair easily with my Edge 500. During my first ride, speed recording was intermittent, sometimes showing zero or values clearly wrong. The cadence readings seems to be ok.
I returned the sensor to the LBS and they gave me a new set. The problem still persists. Is there any compatibility problem with 500 or am I just very unlucky to get two different units with the same problem?
Tried to:
- flip the sensor direction;
- approximate the Edge unit to the sensor (when trying with the bike mounted on a repair stand).
- remove the battery, wait 30 seconds
No improvement.
I've also measured the battery voltage using a multimeter, it shows 3.02V.
Do someone have a clue of what may be happening?
PS: On my other bike, with conventional sensors, I get correct readings using the same Edge 500 unit.
