When performing the optics alignment for the first time after installing
the MiniFlex 600, select Options - Detector Setup - D/teX Ultra, and
enter the same value as Low value in the PHA baseline, and High value
minus the Low value in the PHA window box as the initial value. The
Low value and High value are indicated on the label attached on D/teX
Ultra (see Fig. 5.16). This procedure is unnecessary if the alignment is
already executed and the correct value is entered. Move on to

.
PHA baseline:
Low value written on the label attached on D/teX
Ultra
PHA window:
Value determined by subtracting Low value from
High value. Both are written on the label attached
on D/teX Ultra.
