When performing a zero reset on a left/right Stages Power meter in the Stages Power app, you will notice you receive separate values for ADC and temperature for each corresponding power meter. These readings will not match exactly between left and right sides, but this does not indicate a problem. 


Each power sensor is calibrated individually as a single meter and has been programmed to adjust power readings based on its own sensor.  As long as both sensors are adjusting for increases and decreases in temperature, the temperature readings do not need to match between both power meters in a left right set.
