Basic Knowledge for Operation

The ZG2 series is a non-destructive type sensor that measures cross-section shapes by
emitting a wide band of laser light onto the object and capturing light reflected from the
object by a CCD. This CCD imaging information is used to generate a profile of the
object's shape, and dimensional shapes, such as height, steps, width, position, points of
intersection, inclination, and cross-sectional area, can be measured instantaneously from
the cross-section shape of the object.

Profile Screen

A cross-section shape of the measurement object displayed on screen is called a
"profile." Profiles are displayed on screen as a yellow line.
In the RUN/ADJ modes, the measurement state can be visually checked by these
profiles. Also, in the FUN mode, profiles can be used to set the measurement conditions.
Height measurement items are already set as the default, so it is possible to know
immediately the detection status of the Sensor Head by setting the operation mode to the
RUN mode.
On the ZG2 series, measurement points in the height and width directions are measured
on the vertical (Z-axis) and horizontal (X-axis) axes, respectively. Measurement values
are displayed as numerical values prefixed with a + (plus) or - (minus) sign depending on
the coordinate position.
