The monitor is placed in a calibration mode in which it reads the output signal from the sensor and normalizes the output signal to a convenient scale. The normalized reading is used to compute a calibration coefficient. The calibration coefficient is stored in a non-volatile memory integrated with the carbon monoxide monitor. | |
