Display setup for spectrum
B1. Display Setup for measurement: Spectrum / Time waveform
Zoom: Step size when zooming the
X and Y-axis
.
Zoom Mode
: The zoom is made around the main cursor or the
gap between the delta and main cursor.
Cursor: Cross (
short
) or line cursor (
long
);
line type
for the line
cursor
Graph type: A spectrum can be displayed in a
curve diagram
('continuous')
or a
bar chart ('poles')
. 'Gradient' colors the area
under the graph. For a sound spectrum select the 'octave' or
the 'third octave' option. A time waveform can be displayed
in Cartesian coordinates (
X-Y diagram
) or on a
circular plot
.
When taking measurements with DC coupling, the DC component
in the signal can be hidden (Option: ‘AC only’).
Suffix for 1/1000 or 1000: Instead of '1/1000' or '1000', the X-axis
can be labeled with the abbreviation 'm' (milli) or 'k' (kilo).
Amplitude (spectrum): Amplitudes in
RMS
or peak values (
0-peak,
peak-peak
). RMS value of entire spectrum: see p. 4-11.
Order display (spectrum): Scaling of the X-axis in Hz (
No
) or orders
(
Yes
). The shaft RPM must be known (measured or entered).
Amplitude scaling (spectrum): linear or logarithmic (in decibels).
Default display mode (spectrum): Information that appears in the
lower pane by default (
Max 10, time waveform, band alarms,
frequency marker, trending parameters, cursor coordinates
).
Speed Marker (Time signal): Display of the trigger signals in the
diagram. In the circular plot, the arrow indicates the direction of
rotation.
Continuous measurement (live mode): see section X on page 4-17.
B2. Display Setup for Trend: Spectrum (Waterfall diagram)
Cursor & Amplitude: s. section B1; in a waterfall diagram, a
grid
can
be superimposed for easier evaluation of the data.
