Cursor Mode – Only available for Spectrum plot displays. The button cycles through the following four modes.
Normal (gauge values) – A free-moving single cursor provides a point for each trace displayed. This is the
only cursor that can be used with multiple traces.
Harmonic – Can only be used when 1 trace is displayed. Results in several cursors positioned to the right of
the primary cursor and at intervals that are at twice the x-axis value of the primary cursor. For example: When
the primary cursor is at 100 Hz, the first harmonic cursor will be at 200 Hz, the second at 400 Hz, the third at
600 Hz, etc. Moving the primary cursor to 400 Hz would result in the first harmonic cursor residing at 800 Hz,
the second at 1200 Hz, etc. If Display Gauge Values is selected, the applicable values will be shown for all
cursors. Harmonic cursors can only be moved by moving the primary cursor.
Side Band – Can only be used when 1 trace is displayed. Results in several cursors spaced at even intervals
on both sides of the primary cursor. Unlike the harmonic cursors, the sideband cursors can be moved by the
user. Once adjusted, they remain in position at until the next adjustment. If Display Gauge Values is selected,
the applicable values will be shown for all cursors.
12
Peak List – Can only be used when 1 trace is displayed. On a real-time or playing plot, the cursor will
automatically position itself at the highest point on the trace.
13 Annotation - Active with Polar, Waterfall, and Shaft Centerline Plots. Use this button to superimpose RPM or Time
values onto the displayed data.
14 Overlay Limits – For Spectrum, Stripchart, and Polar plot windows. Superimposes the limit values onto the displayed
data.
15 Runout Compensation – displays a graph of the RunOut compensated values. RunOut compensation is a vector math
operation in which the referenced first-order amplitude and phase vector is subtracted from the displayed first order
vector. This option is only available for Bode and Polar plots.
16 Overlay Bearing Clearance Circle – Superimposes the bearing clearance circle over the plot display. This feature can
be used with the following plot types: Orbit, Shaft Centerline, Bode, Stripchart, and Time Waveform.
17 Band Pass Filter Selection – Used with Time and Orbit plots. Allows the user to apply an nX filter to time data for Time
and Orbit plot displays.
18 Shaft Revolution Filter – Used with Time and Orbit plots. This filter selection is used to limit the amount of data
displayed. The limitation is set by selecting “n,” where “n” is equal to the number of shaft revolutions. The Shaft
Revolution Filter is used to make the plot display cleaner by reducing clutter from excess data.
