When Using Measurement Results Externally (Scan Edge Position)

Values Available in Expression

When this processing unit is selected in the "Unit" area of the Setting Expression window, the measurement items available in expressions are displayed in the sub-menu.

The measurement items displayed in the sub-menu are explained below.

For how to set up expression, see
