If no operations are performed while the displays are flashing, direct
measurement mode will end in the time selected for Custom Setting c2
([Auto meter-off delay], pg. 279). The default setting is six seconds.

Presetd-O
The new value for white balance will be stored in
preset d-O, automatically replacing the previous
value for this preset (no confirmation dialog will
be displayed). A thumbnail will be displayed in
the preset white balance list.
To use the new value for white balance, select preset d-O (if no value has
been measured for white balance before d-O is selected, white balance
will be set to a color temperature of 5,200 K, the same as [Direct sunlight]).
The new white balance value will remain in preset d-O until white balance
is measured again. By copying preset d-O to one of the other presets
before measuring a new value for white balance, up to five white balance
values can be stored (pg. 141).
