■操作步骤operation procedure
固定好光电开关,使检距符合要求。根据您使用的需要确定开关的光源；再根据工作需要选择亮动或暗动，并按照以下三步骤调节灵敏度。
1、移动包装纸或我们称之为底色、让投光点落到标记之外的背景区；将灵敏度旋钮反旋到底，然后顺时针慢慢转至指示灯刚好亮，记住此时电位器位置如图（一）的A点。若旋到高点的位置指示灯都不亮则高位置就为A点。
2、再移动包装纸让投光点照在需检测的标记上、指示灯应是亮的，此时应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的位置;如图（二）的B点.
3、正确完成以上两步后,再将电位器旋到A点与B点的中间即可如图（3）调节完毕。A、B两点距离越大说明色比较大检测越稳定但A、B两点*少要有一格的距离否则检测将不稳定。
Fix them in accordance with the demands of the testing distance.Then according to the 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 outpue mark sensors on is a bright 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 tumed to the High position ａnd the indicator light still does not turm 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.
