151 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:1. Prepare a commercially available power meter.ワㄐㄕㄊㄆ• 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 1kW/cm2should be used.• Also the size of the detector should be more than φ20 mm.• A difference may arise under the high/low temperature. Measuring power with normal temperature (20 to 30 Celsiusdegree) is recommended.• Before measuring the laser power, make sure there is no contamination in the laser emission port. If the laser emissionport 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 thefollowing distance, i.e. one-third to half of the specified work distance of the laser marker.Laser marker model Installation distance for detector of power meter *LP-GS051 Approx. 45 mmLP-GS052 Approx. 35 mm* The values represent the recommended values for the case where the damage threshold (maximum average powerdensity) of the detector of power meter is 1kW/cm2.Laser marker headDetector of power meterLaser beamWork pieceInstallation distance fordetector of power meterWork distance(at base position)ワㄐㄕㄊㄆ• Do not install the power meter within the focal length of the laser marker. This may cause destruction of the power meter.• Do not use “guide pointer” function to confirm the setting position of the power meter detector. Since the guide pointeris emitted obliquely, with the above described installation distance, guide pointer does not indicate the center of themarking field and you cannot use it as a reference.ME-LPGS-SM-8
