6.3.2 Automatic Full-Scale Range Setting

The OPT4041 has an automatic full-scale range setting feature that eliminates the need to predict and set the optimal range for the device. In this mode, the device automatically selects the optimal full-scale range for varying lighting condition each measurement. The device has a high degree of result matching between the full-scale range settings. This matching eliminates the problem of varying results or the need for range-specific, user-calibrated gain factors when different full-scale ranges are chosen.
