SELECT SURFACE
Select one or two surfaces to be measured from a
maximum of four measurement target surfaces. The
number of surfaces to be selected differs according
to the setting of [MEASUREMENT].
[MAX] (Maximum)
[MAX] measures the target surface of the highest
light intensity peak picked up from the peaks that
exceed the light intensity level. [MAX] can be
performed on many measurement targets including
an opaque object to measure its displacement and
slant.

[M1], [M2]
[M1] and [M2] measure the highest and the second-
highest light intensity peaks picked up from the
peaks that exceed the light intensity level. The one
nearer to the measuring unit is measured as M1 and
the other as M2.
It is useful to measure the surface displacement,
backside displacement and thickness of a target
such as transparent glass that has very close
measured values on the surface and backside.
To measure in [M1] and [M2], more than one light
intensity peak exceeding the light intensity level is
needed.
