■ 操作步骤operating set_up
Fix them in accordance with the demands of the testing distance then according to thr packing paper you use,refer to the Guide Grids（for reference of light source choice）to decide on the light source（take the green one as example）,and then decide the bright mark sensors on or the dark one to meet your machine’s need.Now you can adjust the sensitivity according to the following three steps（take,as example,that the output mark sensors on is a bring one,the packing paper is of light color ａnd the background is dark color）.
First,move the packing paper,cast the light on the background outside the sign.Turn the sensitivity control counter clockwise till to the end,then turn it clockwise till the indicator light just turns red,and remember the position of the sensitivity control is in the position of Point A as in Picture 1.If the sensitivity control is turned to the “High”position ａnd the indicator light still does not turn red,then the “High”position is Point A.
Second,move the packing paper again,and when you cast the light on the center of the sign,the indicator light will turn red.Then turn the knob counter clockwise slowly till the indicator lamp just goes out,and remember the sensitivity control is in the position of Point B as shown in Picture 2.
After operating the above two steps correctly,you can then turn the sensitivity control to a position between Point A ａnd Point B,that is,Position C as shown in Picture 3,and now the adjustment is finished.The longer the distance between Point A ａnd B is,the higher the ratio of the chromatic aberration ａnd the stabler the test will be.The distance must be at least one scale between Point A ａnd Point B,otherwise the test will not be stable.
固定好光电开关，使检测距离符合要求。根据您所用的包装纸用色标颜色确定光源,（以绿色光源为例）再根据您机械的需要决定输出方式的亮动或暗动.按以下三步调节灵敏度（以下以输出方式,包装标签纸为浅色,背景为深色为例）（1）移动包装纸, 使投光点落在标记之外的背景区,将灵敏度反向旋到底,然后顺时针慢慢旋至指示灯恰好亮记住此时电位器位置如图1的A点位置。（2）再移动包装纸,使光点恰好落在标记中央,然后逆时针慢慢旋转灵敏度旋钮直至指示灯恰好熄灭记住此时电位器位置如图2的B点清位置。（3）正确完成以上两步后,再将电位器旋到A点与B点的中间C位置即可如图（三）此时调节完毕.A,B两点距离越大说明色差比较大,检测越稳定.
