When the proper adapter is mounted to the MAVOSPEC, the Menu "Sphere Correction"
will be displayed in Quick config panel.
Before performing the actual self-absorption procedure, start the procedure with the
open sphere and check if the auxiliary light source is being turned on during the
measurement, as well as the yellow diode on Sphere Controller. If not, the wiring of
Sphere Controller as well as settings of COM port has to be checked.
When the auxiliary light source works correctly, remove the DUT (Device Under Test)
from the sphere together with the post, open Sphere correction dialog once again and
click the Next button.
NOTE: Cover the entrance aperture to cut off the ambient light.
