prompted to perform the System Check. Press Ok when asked to mount
the wafer.
6. In the Sample Alignment dialog box, select Automatic-Quick under the
Sample Height Alignment drop menu. If the calibration wafer has already
been aligned, click ‘Current Position’ to enter the current Z-height. Press
OK. This will take 1-2 minutes. If the System Check is successful, the
system is now ready to take data.
7. If the Psi and Delta data show a “step” at the Detector Switch Point (for
NIR systems), the Receiver unit may need to have the iris(es) opened up
(shown in Chapter 4). They may have been closed previously to avoid a
detector overload, but with the focusing optics present and off sample,
they can be opened to allow more light into the fiber(s).
