Calculating Between the Heads
The surface displacement, thickness, and height-difference measurements can be performed
by calculating the data acquired from the setting of head A or head B according to the
measurement target.
■
Function Nos. and measurement examples
* Used in combination with the auto offset function.
When transparent object is selected for the measurement mode of head setting, head A and head B perform
surface measurement if
Add-Ab
or
Sub-Ab
is selected.
