Our hack begins with the datasheet for the meter’s microprocessor. [Kerry] then tacked on a few wires, and dumped, modified, and reflashed the calibration and configuration EEPROM. With a single ...

Properly calibrating your e-bike motor for cold weather can significantly improve performance and battery life during winter ...

If true, this would make the meter unlikely to have any way to field calibrate it. Of course, the meter may calibrate itself on startup using some known internal reference, but it is hard to tell ...

Calibration is the process of assigning engineering units and uncertainties to digital counts (or meter deflections if measuring a current/voltage/resistance, etc ...
