average height of and OMRON standard measurement object for the
beam line. The CCD high-resolution mode is used. Linearity varies de-
pending on the measurement object.

Note: 1 . Obtained by setting an OMRON standard measurement object at the
measurement center distance and determining the average height of
the beam line. The conditions are given in the table below. However,
satisfactory resolution cannot e attained in strong electromagnetic
fields. The minimum resolution of the ZG2-WDS8T/WDS3VT is
0.25 µm, even when the average number of operations is increased.
Resolution does not go any lower.

. A value attained by using an aluminum jig to secure the distance be-
tween the Sensor Head and the measurement object. The CCD stan-
dard mode is used.
4 . Defined as 1/e

enced when light leakage also exists outside the defined area and the
reflectivity of the light around the measurement object is higher than
that of measurement object.

2 . Data is saved in the memory of the main unit during logging. The data
is automatically saved in a memory card after logging is complet-
ed.The maximum number of logging differs according to set condi-
tions. For details, refer to the Users Manual.
