It is important that the measurement aper-
ture always covers the color patches com-
pletely during the entire scan.
When using color bars with a patch height

smaller than 4,5 mm, the edge of the mea-
surement head of the device has to be placed
exactly at the upper edge of the color bar, to
ensure that the measurement head is posi-
tioned correctly on the patches.
 When using color bars with a patch height
higher than 4,5 mm, the measurement head
has to be placed with the measurement aper-
ture at the bottom edge of the color bar.


move the measurement device from the hori-
zontal track, position it with the measurement
head on a single measurement patch and
press the green measurement button shortly.
