Display setup
Display setup for time waveform
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.
