3. Select the buffer to display. The data or statistics are displayed.
•
If data is being recalled, the reading display is on the top left, and the buffer location number is on the
right. The source values are positioned at the lower left side of the display (if enabled); the timestamp (if
used) is positioned at the lower right side.
•
If statistics are being recalled, the information includes values for MEAN, STD DEV, SAMPLE SIZE,
MINIMUM, MAXIMUM, and PK-PK.
•
The source display field identifies the buffer: SrcA1 (buffer 1) or SrcA2 (buffer 2).
Buffer location number
The buffer location number indicates the memory location of the source-measure reading. For
example, location #000001 indicates that the displayed source-measure reading is stored at the first
memory location.
Timestamp
If the timestamp is enabled, the first source-measure reading stored in the buffer (#0000001) is
timestamped at 0.000 seconds. Subsequent readings are timestamped relative to when the first
measurement was made. The interval between readings depends on the reading rate.
