Illuminant/Observer Selection...continued
3) To exit press [FUNCTION].
When "Function Key" is pressed,
the instrument will automatically
convert the stored spectral
references (if any) to tristimulus
for the different illum/obs
selected. The unit will also ask if
you would like the references to
be cleared. If you do not want the
references cleared (or you do not
have any entered), disregard the
procedure below.
Clearing References
The "Clear Reference" function is
useful if the Illum/Obs is being
changed often, and many
references exist in the instrument
that are not being used. This will
enable the operator to speed up
the time it takes the instrument to
recalculate to a different
illum/obs.
Press [DIF] to enter clear reference
function. After the "Dif Key" is
pressed "CLEAR REFERENCES
↓NO YES↓" is displayed. Press
[DIF] to clear or [FUNCTION] not
to clear.
> You must press the "Dif" key
while the unit is recalculating
the references to activate this
function.
> If the clearing procedure is
carried out, all references
(measured & numerically
entered) will be removed.
> Refer to Section 3.5 for a more
detailed explanation on
measured and numerically
entered references.
