| *1 The laser classification for FDA(CDRH) is implemented based on IEC60825-1 in accordance with the requirements of Laser Notice No. 50. *2 This value is from a case in which measurement has been performed with a reference distance with 4,096 times of averaging. *3 The measurement targets are KEYENCE standard targets. This value is from a case in which the average height of the default setting area has been measured in height mode. All other settings are default. *4 The measurement target is a pin gauge. This value is from a case in which the position of the intersection between the rounded surface of the pin gauge and the edge level has been measured in position mode. All other settings are default. *5 The measurement targets are KEYENCE standard targets. The profile data is from a case in which measurement has been performed with 64 times of smoothing and 8 times of averaging. All other settings are default. *6 The linearity will differ depending on the measurement area. *7 For high-speed mode, when the measurement area is at its minimum, binning is ON, image capture mode is set to standard, and parallel image capture is ON. All other settings are default. For advanced function mode, when the measurement area is at its minimum, binning is ON and image capture mode is set to standard. All other settings are default. *8 This value is from a case in which the sensor head cable (CB-B*) or extension cable (CB-B*E) has been connected. *9 This is the illuminance for the light-receiving surface of the sensor head during white paper measurement when light has been shined onto the white paper. *10 The sensor head must be mounted on a metal plate for use. |
