SETTING THE CAPTURE PERIOD
By default, the feature is enabled with the capture period set to once per hour and Channels 1 through 16 selected
for capture. With these settings, the values of the first 16 Meter and Status channels are saved at the top of each
hour.
The capture period can be set in increments of 10 seconds, with the smallest allowable period being 10 seconds.
The maximum period that can be set is approximately 182 hours. Actual capture times are calculated by repeatedly
applying the period beginning at midnight the night before the value was programmed. For example, setting the
period to 001:15:00 (one hour and fifteen minutes), results in potential capture times at midnight, 1:15AM,
2:30AM, 3:45AM, etc.
SPECIFYING CAPTURE CHANNELS
Captured data always includes Channel 1, and can be set to include up to the entire 256 channels. A large block of
memory is reserved to store the captured values locally on the ARC Plus SL. When this memory fills up, the oldest
set of captured data is discarded, making room for a new capture. In this way, the most recent captures are always
available for download via AutoPilot. The table below gives examples of the number of captures that can be stored
in the available memory before the oldest capture is discarded.
Caution: Changing the Highest Channel causes the ARC Plus to erase all previous captures.
Download the captures with AutoPilot before changing this value.
