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 ...

Sadly this chip has no serial port, but he did find an I2C EEPROM which he correctly guessed held calibration settings. Removing this chip gave him a meter with slightly off calibration ...

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

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