● Reading waveforms continuously
When continuously reading waveforms with the same waveform ID, repeatedly send the
commands described in
3.
and subsequent steps. The update interval of compressed
waveform information is 64 ms. Leave an interval of at least 1 ms when sending each com-
mand.
5.
To check the beam axis status, execute either of the following commands.
5-1.
To check the beam axis adjustment status after reading the waveform,
send the “Beam axis adjustment status at the time of waveform reading” command
(READ). (Command code: 0x03B1)
5-2.
To check the beam axis adjustment status without reading waveforms,
send the “Beam axis adjustment status” command (READ). (Command code: 0x0361)
If the response is normal, the following response data will be returned.

Beam axis state Reserved
Details of beam axis status
Bit15 Bit14 Bit13 Beam axis state
0 0 0 Immediately after beam axis adjustment starts
0 0 1 Beam axis aligned state
0 1 0 Receiver has shifted toward TOP side (emitter has shifted toward BOTTOM side)
0 1 1 Receiver has shifted toward BOTTOM side
1 0 0 Beam axis is completely out of alignment (fully blocked state)
1 0 1 The light intensity is too much
1 1 0 The light intensity has decreased
1 1 1 Objects intercepting light or stains (adhering substances) exist inside measurement area
6.
To register the reference waveform after checking the beam axis adjustment status, send
the “Reference waveform registration execution” command (WRITE). (Command code:
0x0362)
Write data “0”.
Notes: 1) To save data in EEPROM when registering the reference waveform with the command, set the “Refer-
ence waveform save [BW.SAVE]” command (READ/WRITE) (command code: 0x0307) to ON before-
hand.
2) By default, data is not saved in EEPROM when the reference waveform is registered with the com-
mand. When the power is turned OFF and then ON again, the reference waveform returns to the pre-
registration state.
After the command is executed, the system is automatically reset from beam axis adjust-
ment mode .
