Checking
After calibration, set the Measurement Aperture on the Checking Tile
( Spare Working Standard ). A deviation between the shown value and
the labeled value should be less than or equal to 1 GU. If the deviation
goes beyond this scope, it's shown that the certified gloss values of the
working standards may be changed. Thus the gloss values should be
certified again.
Check a meter only when it is used for a long period, or a result of
measurement is doubtful. It is not necessary to be check for every
time measuring.
