1. The value obtained after 64 times Averaging at the reference distance.
2. The target is KEYENCE standard object. (White diffusing material). The value is the average of the widths in the Height mode.
3. The target is ø10 mm pin gauge. The value is the edge in the Position mode after 16 times of the Smoothing.
4. When the measuring range is the minimum in the initial setting.
5. The illumination on the receiver of the sensor head when targeting an illuminated white paper.
