Confirm not to change the output data at measuring AF input condition (1 to 4), when you shorten intervals between stationary ray hold and distance measurement integration beginning to MIN 26 S. The value in this item is less than "max" value at any cases. Set AFOUT capacity, distance measurement integration time, and the number of integration under max value, because the "max" value in this item indicates a maximum of IC dynamic range. Establish optional system to be input current to IC less than standard value, because this item's value indicates maximum input current to IC.
