t mark out of the box. The screw is not blocked with one hand so you have to get a third Put your hand to keep the sensor distance at the same level, and also screw it with two hands without losing the mark, because the sensor is quite loose without the screw tightened.In general, it is difficult to operate, but it can be improved by some adjustment I advise you to place this sensor on a table with the screw on the edge of the table so it doesn't roll off the edge of the table as it is light weight and rolls easily.
