Item 10, fi g. 5.3.
Sliding your fi nger up and down the icon will respectively increase
and decrease the display brightness. Tapping the icon will change the brightness to
the point where it is tapped.
5.2.14 Cleanliness level settings icon
Item 11, fi g. 5.3.
This icon allows access to setting of the alarm levels associated
with the selected reporting format.
Alarms can be set on combinations of cleanliness codes, water content and
temperature. The available codes, and their interpretation, vary according to the set
test Format. For example, it is possible to set a threshold of “NAS 11” or
“ISO 18/16/15” or “AS4059E 8B-F”, etc.
In general, there are upper and lower limits that can be set for the cleanliness level,
also for water content and temperature if applicable. An alarm, if enabled, will
become active if any of the associated (upper/lower) limits are exceeded.
However, if a fi eld is left empty (blank) this is interpreted as a “don’t care” setting.
