■ LK-G505/LK-G500/LK-G507/LK-G502
The measurement range is shown in the figure below.
*1 The value inside the parentheses ( ) is when the sampling rate is 50 µs.
*2 The value inside the parentheses ( ) is when the sampling rate is 20 µs.
Note that the measurement range narrows in either case, disabling measurements at the
reference position.
• The laser emission LED at both diffuse reflection and specular reflection lights in
green within ±12.5 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.
When using LK-G505/G500/G507/G502, select function No. G-1 or G-0 (page 33).
The measurement range when measuring a mirror surface or a glass surface at the time of
specular reflection setup is between +173 (NEAR side) to +49.5 mm (NEAR side). When the
sampling rate is 50 µs, the value becomes +173 (NEAR side) to +125 mm (NEAR side). Note
that the measurement is disabled when the sampling rate is 20 µs.
