13.6.1 f Stop Display Description
To set f Stop, press F•1 CINELITE DISPLAY to select f Stop and then press F•2 f STOP
SETUP.
On the f Stop display, luminance levels are displayed using f-stop (exposure) values.
The measured f Stop value for a group of measured points is typically displayed using white,
but it will be displayed using yellow when it corresponds to a luminance level of 80 % or
more. Additionally, f Stop values that correspond to luminance levels equal to or less than
0 % cannot be measured. They are displayed in yellow as "****."
