eZ-Analyst 916994 Toolbar Buttons 5-7
Note: Items 31 through 35 are located at the right end of the toolbar. They are not shown in the
preceding toolbar images due to the width of the complete toolbar graphic. Pages 5-9 and 5-10
depict the types of displays that result from using combinations of these four buttons.
31 32 33 34 35
Function Description / Comments
31 3D Waterfall
View
Used to bring up a 3D Waterfall display.
32 Frequency or
Orders
Slice View
Brings up a display for a chosen frequency. This is a “slice” of
the waterfall or order tracing, taken at a given frequency (or
order).
33 Spectrum
Display Split
View
Brings up a standard spectrum display plus allows for a second
display, either 3D Waterfall or Frequency Slice, but not both.
34 Order Tracking
or Frequency
View
Order
Tracking
This button is used to enable the Order Tracking display mode
or the Frequency View mode.
The Order Tracking display mode provides a means of displaying
data from points which are evenly spaced by RPM, instead of
increments of time. On the x-axis scale of the Order Tracking
display: 1 equals shaft RPM, 2 equals 2 x Shaft RPM, 3 equals 3
x Shaft RPM, etc. Order Tracking presents data in the frequency
domain. To use Order Tracking a tachometer must be assigned
to an enabled channel.
Note that if the and buttons are
both enabled, eZ-Analyst displays the slice view above the order
tracking view. The Order Tracking display can be enabled from
either the Measurement (Real Time) mode or the Playback
mode.
Frequency
View
The Frequency View mode is the standard eZ-Analyst spectrum
view. When this view is enabled the button appears as shown
to the immediate left.
35 Tach Selection
( for use with
Order Tracking )
This pull-down selection list of available enabled tachometer
channels is visible on the toolbar only when Order Tracking
(Button #34) is enabled. The selected tach will apply to
each enabled input channel. Select “Default Tach” when you
want to assign each channel to its default tachometer [as
determined in setup configuration].
Note: Buttons 31, 32, and 33 are enabled for most single-display spectral function views (FV). They are
never enabled for time function views as the x-axis must be in frequency. Any two of these three
functions can be displayed at the same time. See table on followig page in regared to button
combinations and resulting displays.
In regard to button # 34, to enable Order Tracking click the button after verifying the following:
o at least one tachometer is assigned to a channel
o the tach channel is enabled
o no dual-function window is open, e.g., no FRF (see item # 8).
