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 ...

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

Use a multimeter to check voltage levels ... Always refer to your e-bike manufacturer’s guidelines for specific calibration settings. Have you tested your e-bike’s performance in cold weather?
