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 ±0.75 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 +14 (NEAR side) to –8.2 mm (FAR side). When the
sampling rate is 20 µs, the value becomes +14 (NEAR side) to +8.7 mm (NEAR side).
