⿎ Laser Check
Execute the laser check when measuring the laser power to be applied for radiation using power meter.
WARNING
1.
Press [ADJUS.] in the operation screen.
2.
Press [LSR.CHK. (Laser Check)].
3.
By pressing [START] laser will be radiated to the central of
marking field.
4.
The laser radiation is stopped by pressing [STOP].
Even without "stop" or "interrupt" command, the laser radiation
automatically stops after about one minute and the shutter is closed.
Reference
• Use the laser check function when measuring the laser power output with the commercially available laser power meter.
• When the laser it needs to radiate the laser only to one point for the purpose of the laser marker being performed as the
processing device, use the arbitrary point radiation function. Refer to "4-10-6 Point Radiation Condition" (P.212).
• In laser check function, only the following settings are valid.
• Laser power
• Laser pulse cycle (only LP-V / LP-W series)
• Duty cycle (only LP-W series)
• Laser frequency (only LP-400 series)
• Power offset in system offset setting
CAUTION
• Be sure to use the protective goggle and enclosure during radiating laser.
• During the radiation, the laser energy is concentrated to one point. Use due
caution with long period radiation, it may cause a fire or damage to the object.
• Once the laser check is started, the radiation will not be interrupted until [Stop]
is pressed.
• For the laser power measurement, use a laser power meter that has the
damage threshold (max. power density) of more than 10 kW/cm
• The laser detector diameter of the laser power meter should be more than 10
mm.
• Place the detector of the laser power meter at the one-third to half of the
specified work distance of the laser marker. Do not place the power meter
detector at the focal point (specified work distance) of the laser marker. It may
cause damage to the power meter.
