OSCILLOGRAPH SETUP
The Oscillograph Recorder provides comprehensive
data recording (voltage, current, and status input/
output signals) for all monitored waveforms (at 16,
32 or 64 samples per cycle). Oscillograph data can
be downloaded using the communications ports to
any PC compatible personal computer running the
CapTalk
®
S-6280 Communications Software. Once
downloaded, the waveform data can be examined
and printed using CapPlot Analysis Software. The
waveform data is also available in COMTRADE file
format. Oscillograph records are retained if power
to the control is interrupted.
The general information required to be input to
complete the Oscillograph Setup includes:
• Number of Partitions – When untriggered,
the recorder continuously records
waveform data, keeping the data in a buffer
memory. The recorder's memory may be
partitioned into 1 to 16 partitions. Tables
4-1, 4-2 and 4-3 illustrate the number of
cycles of waveform data per partition.
When triggered, the time stamp is
recorded, and the recorder continues
recording for a user-defined period. The
snapshot of the waveform is stored in
memory for later retrieval using CapPlot
Analysis Software.
• Samples/Cycle – The number of samples/
cycle can be selected to either 16, 32 or
64 samples/cycle.
•
Post-Trigger Delay – A post-trigger delay
of 5% to 95% must be specified. After
triggering, the recorder will continue to
store data for the programmed portion of
the total record before re-arming for the
next record. For example, a setting of 80%
will result in a record with 20% pretrigger
data, and 80% post-trigger data.
•
Inputs and Outputs
– The recorder
can be triggered remotely through serial
communications using CapTalk, or
automatically, using programmed status
signals (Figure 4-13).
