The measurement range is shown in the figure below.

* The value inside the parentheses ( ) is when the sampling rate is 20 µs. Note that the

measurement range narrows, disabling measurements at the reference position.

• The laser emission LED at both diffuse reflection and specular reflection lights in

green within ±2 mm of the reference position, and lights in orange in the other
positions in the measurement range.

• Select the mounting mode (

page 3-12) according to the installation conditions.

The measurement range when measuring a mirror surface or a glass surface at the time of
specular reflection setup is between +39 (NEAR side) to –24 mm (FAR side). When the
sampling rate is 20 µs, the value becomes +39 (NEAR side) to +22 mm (NEAR side).
