Storing readings

You can append measurements to the reading buffer or override existing measurements in the
reading buffer.
Complete the following steps to append or override measurements:
1. Set up the SourceMeter for the desired settings and buffer configuration using the
configuration menu described above.
2. Turn on the output.
3. Press CONFIG > STORE and then select TRIG-MODE.
4. Choose one of the following:
– APPEND
– OVERRIDE
5. Press EXIT to return to the main menu.

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 Channel A and then Channel B (Model 2602/
2612/2636 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 time stamp (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 2602/2612/2636 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.
Time stamp
If the time stamp is enabled, the first source-measure reading stored in the buffer (#0000001) is
time stamped at 0000000.001 seconds. Subsequent readings are time stamped relative to the
time storage was started, and the interval between readings will depend on the reading rate.
