FCU display
The particle sizes displayed can be selected with the keys
+
and
.
The "tendency arrow" serves to display even very slight changes
(: increasing contamination,
↓
: decreasing contamination). It even
indicates changes which would not otherwise be remarked upon by the
specification of Contamination Class alone.
If the determined contamination lies above the specified display range
(see page 99), >25 >23 or >12 / >15 are shown in all particle size
ranges.
5 One can select between differential and cumulative displays of
numbers of particles by using the keys
. The selected
presentation is indicated in the display by a "D" (differential) or "C"
(cumulative) behind the display of the expired measurement time.
Differential representation means: particle count in the particle size
ranges:
FCU 201x:
5-15 µm, 15-25 µm, 25-50 µm, >50 µm
FCU 211x:
2-5 µm, 5-15 µm, 15-25 µm , >25 µm
FCU 221x:
4-6 µm

, 6-14 µm

Cumulative representation means: particle count in the particle size
ranges:
FCU 201x:
>5 µm, >15 µm, >25 µm, >50 µm
FCU 211x:
>2 µm, >5 µm, >15 µm, >25 µm
FCU 221x:
>4 µm

If the determined particle count lies above the specified display range
(see page 99), ">>>>>>>“ is shown in all particle size ranges as the
particle count.
