I recently bought a Pioneer dual sided power meter, but it's not working properly. Both left and right side have new batteries and display an orange light, so it's in dual sided ant+ mode. When I search the power meter I find him directly. Calibration is performed as instructed but gives very high values like 11847. When I ride it, most of the time I get no reading, sometimes it gives some reading but this is incorrect. What is wrong or what can I do?
