5.2 ADJUSTING GRAPH VIEWS – DISPLAY SCALE
The Display Scale list of parameters allows
you to define the result units (absolute or
logarithmic), number of digits after decimal
point, decimal mark, adjust scale of charts and
toggle a grid.
Scale of results presentation
The Scale parameter defines results units:
linear (Lin) or logarithmic (Log).
For sound measurements the Scale position
is not active. All results are always presented
in dB.
In case of Log, the graphical presentation is
given in the logarithmic scale and the
measurement results are expressed in
decibels (results are calculated in relation to
the values specified in the Reference Levels
screen (path: <Menu> / Auxiliary Setup /
Reference Levels)).
Note: In Vibration modes, parameters can be presented in Logarithmic (dB) or Linear (for example,
m/s
2
) units. It depends on the Scale parameter value. For example, 10 m/s
2
can be presented also
as 140 dB.
Resolution
The Resolution parameter appears when
Scale is Log and defines the number of digits
after the decimal point in the presented
results: one digit after the decimal point
(0.1 dB) or two digits after the decimal point
(0.01 dB).
Scaling the vertical axis
The Dynamics parameter defines the
dynamic range of the plot Y-axis scale. It is
possible to select the range from the set:
10dB, 20dB, 40dB, 80dB, 100dB and 120dB.
