EXAMPLE OF USING THE PAUSE mode

In Figure 1, nine cycles of vibration data have been recorded. Upon entering the Pause

mode, the real time data collection and display are frozen. The 9th cycle of data is at the

bottom of the display and is the active spectrum.

In Figure 2, the 3-D Raster display has been scrolled using the down key so that the fifth

recorded cycle is at the bottom of the display. It is now the active spectrum. The up and

down keys are active as long as data is available, if only one spectrum is displayed on the

screen the down arrow key becomes inactive.

Pressing ! changes Figure 2 to Figure 3 (the 2-D spectral display) where details

associated with the active spectrum (5th cycle) are displayed. In the 2-D display, the

amplitude range may be adjusted to filter out spectral clutter

Pressing ! changes the display to Figure 4 (3-D Barchart). The determination of bar

heights is based upon the default amplitude range. The data may be saved by pressing

^. Pressing ! cycles back to the 3-D Raster display.

NOTE

Only the number of spectrums displayed in the 3-D Raster

display are used to build the 3-D Barchart: If only one spectrum

was visible on the 3-D Raster display, then only one set of bars

would be displayed on the 3-D Raster display.
