6.6.3 Flicker Replay Options
Data replay capability is an important diagnostic feature of the CTS 3.0 system. The end user
has a great deal of control over the replay process. These user settings are located in the
Options menu. The following options are available to control the replay process:
Menu Item Description
Recall Type This option offers four choices for playback of data. Data is stored in
acquisition windows or buffers. For Harmonics, acquisition windows are
either 10, 12 or 16 cycles. For Flicker, acquisition windows are 1 second.
Available recall choices are:
Every Window: Every acquisition window is shown
Every failed/distorted
Window
Only acquisition windows with one or more
failures are shown.
Every Failed Source
Window
Only acquisition windows with high AC source
distortion are shown.
Every Failed Current
Window
Only
Recall Size Amount of acquisition buffers or windows to be loaded from disk to
memory during playback. The more windows are loaded, the further the
user can back up in the data stream during playback. Thus, when
selecting 100 buffers, the replay can be stopped and reversed up to 100
buffers.
The recall size ranges from 0 to 1000 buffers.
Replay Delay Selects the time to wait between display data buffers during replay mode.
On a fast PC, it may be useful to increase this time or the replay will run by
too fast to see anything meaningful.
Available delay times between buffers are 0.0 seconds for the fastest
speed to 5.0 seconds for the slowest speed.
Display Rate This setting determines how many buffers are skipped for display
purposes. While all data buffers are read from disk, only the selected
buffer interval set here is displayed in the graphs.
Available rates range from Every Acquisition to All the way to the End.
The last setting means the data is read from disk all at once and the last
buffer is displayed right away. The user can then back up using the VCR
style keys in the lower left corner of the screen.
