5.12.3 Harmonics 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 each. 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. During delay, you can click on the pause button to
pause.
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.
