Notes:
IMPORTANT!
The standard is dramatically affected
by smudge marks and dust; and must
be kept clean.
The Calibration Values for the white spot are affected by the
environment and cleaning method of the standard.
If the white spot does not measure correctly, it could be that the unit
needs to be calibrated; there is dust in the optics; or the standard has
smudge marks or is dirty.
The ceramic standard should be cleaned using a mild soap and warm
water solution, thoroughly rinsed with warm water, and wiped dry with a
clean, lint free cloth.
