4 -11 Reading received light waveforms (For the HG-T only)
When reading received light waveforms, select measured waveforms, reference waveforms,
or waveforms during beam axis adjustment (Note 1), so that you can read waveform data and
other information.
Note: For details on waveforms during beam axis adjustment, refer to
“4-12 Registering the reference wave-
.
4-11-1 Format of received light waveform
Reading received light waveforms makes it possible to obtain simplified received light wave
-
forms that represent the maximum received light width (CMOS cell) of the receiver by 256 areas
(0 to 255) and the received light intensity by 256 gradations (0 to 255).
●
Measurement start point and measurement end point
Measurement start points and measurement end points can be obtained only in reference
waveform acquisition mode. Obtaining the measurement start point and measurement end point
makes it possible to know the range that is used for measurement within the simplified received
light waveform.

Edge information and edge position
Edge information can be obtained as information indicating a rising edge or falling edge at each
edge position (edge information 1) and effective edge mode information (edge information 2).
Edge positions are points on the borderline between light interception and light entry within the
received light intensity waveform when a measured object is inserted. The edge position on the
top side is 0.
