About distance value
Meaning of the measured distance value x at each step are as follows.
Range of the distance value Meaning
x < 23 Measurement error. Distance cannot be measured due to the influence
of interfering light and noise.
23 ≤ x < 120000 Measured distance value [mm]
120000 ≤ x There is a non light-reflecting object or non-detectable object

8. Multi-echo function
This sensor can receive four reflected waves (1st reflected wave, 2nd reflected wave, 3rd reflected wave, last
reflected wave) at maximum for one step, and can obtain the distance value as well as the level value from each
wave.
When a light transmitting object, rain, fog, dust, and/or a boundary of an object, etc. exist ahead of a laser beam,
both the light reflected by these and the light reflected by the reflective object located behind them return to the
sensor.
The capability of obtaining distance values and the level values from multiple reflected lights in the same
direction such as above is called the multi-echo function.
However, if the distance between two reflective objects is too near, or the reflectance is too low, detection of the
multi-echo may not be possible.
