 * @brief Calibrate the calibration data
 *
 * @param voltage     : Voltage value

 *                      calec   -> calibrate with the standard buffer solution, two buffer solutions(1413us/cm and 12.88ms/cm) will be automaticlly recognized
 *                      exitec  -> save the calibrated parameters and exit from EC calibration mode
