3.2 Presentation of the screen-keyboard group
The
screen/keyboard
group gives to the instrument a modern ergonomy. It mainly participates to the quick
familiarization of the sound level meter.
A press, a touch or a very light finger slipped on keyboard icon is enough to trigger the corresponding action of
the sensitive key.
The
measurement configuration
is made by moving a reversed video cursor in reserved areas, then by
choosing the concerned parameter or function.
For instance:
•
Time weighting and time constant selection:
A or C
and
Slow
,
Fast
or
Impulse
.
•
Selection of measurement mode
Reserved areas appear according to two 3D type formats:
•
Inner shadow to the frame:
simulates a shifted back area in which parameters can be modified or
displayed measurement results.
•
External shadow to the frame:
simulates a shifted forward area in which different propositions of the
menu can be chosen to go to an other configuration or validation screen.
