Adaptive Waveform Capture	The adaptive waveform capture is used to record longer events than can’t be
	recorded with the disturbance waveform capture. For example, using the
	adaptive waveform capture you could get a detailed view of an entire recloser
	sequence. Each time a sag or swell is detected, the circuit monitor triggers
	the waveform capture. The circuit monitor initiates an adaptive waveform
	capture automatically when an alarm condition occurs, or the waveform
	capture can also be triggered by an external device such as a protective
	relay. The unique feature of the adaptive waveform capture is that it can be
	enabled to stop recording at the dropout of the alarm, which allows you to
	capture data while the alarm is true. You can also initiate this waveform
	capture at any time.
	In SMS, for the adaptive waveform capture, you select the sample rate, and
	how many seconds of the event the circuit monitor will capture (see
	Table 8–2). You can also select how many channels to record. Selecting
	fewer channels lets you record more seconds.
	Table 8–2: Available Resolutions for Adaptive Waveform Captures
	Samples per Cycle	Max. Duration
	(Resolution)	(with per-phase current and voltage channels)
	16	110 seconds
	32	55 seconds
	64	27 seconds
	128	13 seconds
	256	6 seconds
	512	3 seconds

Choose fewer samples per cycle when you want to see more total seconds; choose fewer channels to see a longer duration. See the SMS online help for instructions on setting up adaptive waveform captures.

NOTE: The circuit monitor also records the status of up to 16 digital inputs that can be displayed along with the waveform capture. This is configured by default.
