Key installation points

Conventionally, multiple reflective sensors were used to perform this difference check. However, these differences checks were unstable due to the rounded surfaces on the heads of the screws.
With the IV2 Series, three separate locations can be checked simultaneously with a single unit.
Furthermore, the Outline Tool can be used for stable difference checks regardless of the rounded surfaces on the screws and regardless of variations in the brightness due to the reflected light.
