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.

3. A value attained by using an aluminum jig to secure the distance between the Sensor Head and the measurement object. The CCD standard mode is used.
 4. Defined as 1/e2 (13.5%) of the center light intensity.This may be influenced when light leakage also exists outside the defined area and the reflectivity of the light around the measurement object is higher than that of the measurement object.
 5. A typical value of the measurement range (width direction) near the measurement center distance. This is not a guaranteed value.
 6. Protection structure of connector area is IP40.

1. The measurement cycles stated here are values for FIXED/AUTO sensitivity modes. The measurement cycle increases when the MULTI sensitivity/high-speed MULTI sensitivity mode is selected and according to other settings. When the high power mode is set to ON, the shortest measurement cycle becomes 95 ms regardless of the CCD mode setting. Also, when gang-mounting Controllers and Data Storage Units, the measurement cycle increases approximately 22 ms. The actual measurement cycle can be checked by the ECO monitor in RUN mode.

1. The controller link unit is necessary for linking.
 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 completed.The maximum number of logging differs according to set conditions.
 3. Measurement values for 65,000 measurements can be saved even when two sensor controllers are connected and each performs eight tasks.
 4. The value is the maximum number achieved in the following conditions. One sensor controller performs one measurement task. Either profiles or measurement values are logged.
