Piezo Approach

The piezo approach panel (Figure 60, 61) provides functionality to detect the sample surface and compute the sensitivity of the reader sensor (further details are given in the technology reference).

Approach Range: The Z-piezo has an extension range of 20 µm

Start (µm): Starting extension of the Z-piezo

Max (µm): Maximum extension of the Z-piezo

The approach stops if the surface is found before the maximum specified Z-piezo extension.

Step (nm): Incremental extension of the Z-piezo

Tempo (µs): Time interval between Z-piezo extensions
