*1 The value obtained after 64 times averaging at the reference distance.The target is KEYENCE standard object. The value is the average of the widths in the Height mode.
*2 The value obtained after 64 times averaging at the reference distance.The target is ø10 mm ø0.39" pin gauge. The value is the edge in the Position mode after 16 times of the Smoothing.
*3 The target is KEYENCE standard object. The value is the average of the widths in the Height mode.
*4 With initial setting, minimum measuring range, and single smoothing processing
*5 The illumination on the receiver of the sensor head when targeting an illuminated white paper.
