When trying to set the black level it is sometimes difficult to reach any

external light sources, even with the skirt in place.

If in doubt - do as David T suggests for the white luminance value using
PreCal and then set Optical to Standard calibration mode. You'll still need
to set the black level but it will be by eyeball rather than instrument.
Some folk reckon this method is more accurate and consistent - I'm not
arguing either way ;-)
