Remarks
• The internal shutter is automatically
opened and closed at the time of
start and stop of radiation.
• In the readout data this field
indicates the emission on/off of the
laser radiation for measurement.
• To set the subsequent settings
without laser radiation, set the
radiation on/off to "0".
When this data is omitted, laser is
radiated with the power used in the last
settings (or the initial value 20 if the
power has not been specified).
• For LP-GS/LP-RC series, set the
laser frequency (Max. 2-byte).
• For LP-RF series, set the laser
pulse cycle (Max. 5-byte).
Specifies whether the system offset
value of laser power applies to the
power settings of this function or not.
