⿎ Confirm laser output (Daily inspection)
Confirm the laser output regularly in order to maintain consistent marking quality.
The laser output should be measured with a commercially available meter using the following steps:
Reference
• For LP-V/LP-W series, the current power ratio in comparison with the power at the delivery state can be checked by
using "power check" function. Refer to Operation/Maintenance Manual "4-16-4 Power check" (P.265).
1.
Prepare a commercially available power meter.
Notice
• Be sure to use the calibrated power meter.
• The power meter with the detector having the damage threshold (maximum average power density) of more than 10kW/
cm2 should be used.
• Also the size of the detector should be more than φ10mm.
• A difference may arise under the high/low temperature. Measuring power with normal temperature (20 to 30 Celsius
degree) is recommended.
• Before measuring the laser power, make sure there is no contamination in the laser emission port. If the laser emission
port is contaminated or damaged, an error may result in the measurement of the laser power.
2.
Install the power meter.
Put the detector of the laser power meter vertically down from the center of the laser emission port and place it at the
one-third to half of the specified work distance of the laser marker.

Notice
• Do not install the power meter within the focal length (specified work distance) of the laser marker. This may cause
destruction of the power meter.
