7-4 Buffer (Data Store)
Perform the following steps to store readings:
1.
2.
3.
4.
Recalling readings
Readings stored in the buffer are displayed by pressing the RECALL key.
Repeatedly pressing RECALL will cycle through Buffer 1 then Buffer 2 for Chan-
nel A and then Channel B (Model 2602/2612 only). A message will be displayed if
a buffer is empty.
The reading display is on the top left, while the buffer location number is on the
right. The source values are positioned at the lower left side of the display (if
enabled), while the timestamp (if used) is positioned at the lower right side. When
toggling between buffers with RECALL, the source display field will identify the
buffer: Src1A (Buffer 1, Channel A), then Src2A (Buffer 2, Channel A); followed by
(Model 2602/2612 only) Src1B (Buffer 1, Channel B) then Src2B (Buffer 2,
Channel B).
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 0000000.001 seconds. Subsequent readings are
timestamped relative to the time storage was started, and the interval between
readings will depend on the reading rate.
Displaying other buffer readings
To display the other source-measure readings stored in the buffer, display the
desired memory location number. Use the Rotary Knob to increment and
decrement the selected digit of the location number. Cursor position is controlled
by the Rotary Knob or CURSOR keys.
To exit from the data store recall mode, press EXIT.
2600S-901-01 Rev. A / May 2006
Set up the SourceMeter for the desired settings and buffer configuration
using the configuration menu described above.
Turn on the output.
Press the STORE key. The asterisk (*) annunciator turns on to indicate
data storage operation is enabled. It will turn off when the storage is fin-
ished.
Press EXIT to stop data storage before it finishes.
