26 Maintenance
LP-GS, LP-RF: If you select “Optimal setting”, the software automatically sets the
optimal values for “Laser frequency [kHz]” (LP-GS) and “Pulse cycle [μs]” (LP-RF).
6.
LP-GS051(-L), LP-RC, LP-RF, LP-RV: Use the guide laser to check the position of the
detector.
• Select “Guide laser ON”.
• Set the detector so that the crosshairs of the guide laser radiates on the center of
the detector.
7.
Select “Laser radiation”.
Wear laser protective goggles against laser radiation within the laser controlled
area.
During radiation, the laser power is concentrated onto one point. Long radiation
periods may cause fire and damage to the workpiece.
8.
Select “Yes” to start laser radiation.
9.
Select “Stop” to stop laser radiation.
The laser radiation for measurement automatically stops after about one minute if you
do not select “Stop”.
10.
Check the measurement results of the power meter.
For stable measurement results, it is recommended to obtain the average laser power
value by measuring the laser power after about 30s from the start of laser radiation for
10–30s.
If the measurement value is lower than the specified laser power, change the value for
“Laser power correction [%]” under “System offset” in the “System settings” screen.
Setting range of “Laser power correction [%]”: 50–200
The laser power correction does not change the maximum laser power [W] value. The
correction value is applied to the “Laser power” parameter under “Laser settings”.
If the measurement value is more than 20% below the specified laser power, the laser oscillator
needs maintenance. Contact our sales offices or representatives.
