Setting the Measurement Mode According to the Measuring Target

Specifying the features of the measuring target stabilizes the detection.

Select the corresponding type from the following list.

• To obtain optimal control over detection of the four surfaces, the sampling rate of [Transparent

object 2] is quadrupled at maximum. Be sure to attach the ND filter (

page 1-9).

• When selecting the transparent object, transparent object 2, or multi-reflective object, set

the sampling rate (

page 3-39) to other than 20 µs (other than 20 µs and 50 µs when

transparent object 2 is selected in the LK-G85/G80/G87/G82/G155/G150/G157/G152/
G405/G400/G407/G402, and other than 20 µs, 50 µs and 100 µs when transparent object 2
is selected in the LK-G505/G500/G507/G502).
