CHAPTER 2
– Measurement functions
In
DELTA Mode
(= comparison mode) the
measured values are compared to reference
values. The mode is activated by navigating
to the “soft key” with the triangle symbol and
selecting it.
In the example on the left side a Yellow patch
was measured.
The measured solid density is:
Y = 1.25
This is 0.20 less than the set reference (= tar-
get) density of Y = 1.45.
The measured value is outside the limits of
the set tolerance of ± 0.06. Therefore it is
marked with a cross symbol in the round icon.
A checkmark symbol would be shown in case
of a measurement within the tolerance limits.
The setting of
reference values
and
toler-
ances
is done in the menu under the item
measurement conditions.
In the
Density Reference Setup
up to five
data sets (REF 1 – 5) for reference (= target)
densities can be edited. Reference densities
recommended for the five defined paper
classes are already pre-set.
The tolerances define the lower and upper
limits around the reference values. In this ex-
ample for Yellow:
1.45 + 0.06 = 1.51
1.45 - 0.06 = 1.39
