9-2 Data Store 2400 Series SourceMeter
®
User’s Manual
Data store overview
The SourceMeter has a data store (buffer) to store from 1 to 2500 source-mea-
sure readings. The instrument stores the source-measure readings that are dis-
played during the storage process. Each source-measure reading also includes
the buffer location number and a timestamp. Cmpl will flash in buffer recall if read-
ing is in compliance.
The data store also provides statistical data on the measured readings stored in
the buffer. These include minimum, maximum, mean, and standard deviation.
NOTE When a sweep is performed, the readings are automatically stored in the
buffer.

Storing readings
Perform the following steps to store readings:
1. Set up the SourceMeter for the desired configuration.
2. Press the STORE key.
3. Use the left and right cursor keys, and the SOURCE or RANGE arrow keys
to specify the number of readings to store in the buffer.
4. Press ENTER. The asterisk (*) annunciator turns on to indicate data stor-
age operation. It will turn off when the storage is finished.
5. Turn on the output and (if necessary) trigger the unit to begin taking and
storing readings.
Recalling readings
Readings stored in the buffer are displayed by pressing the RECALL key. The
source-measure readings are positioned at the left side of the display, while the
buffer location number and timestamp are positioned at the right side.
Buffer location number
The buffer location number indicates the memory location of the source-measure
reading. Location #0000 indicates that the displayed source-measure reading is
stored at the first memory location. If limit testing was performed, a “P” or an “F”
will precede the buffer location number to indicate the pass/fail result of the test.
Limit testing is covered in Section 12.
