Viewing and saving buffer content
You can view the content of buffers from the front panel.
However, the front panel may not be flexible enough for your particular type of data analysis. For
further analysis, save the contents of the reading buffer to a USB flash drive. The stored file can be
loaded directly into Microsoft
®
Excel or another tool. The file contains all the information the
instrument records about each data point in the reading buffer. When you save the buffer data, you
may indicate a starting or ending point to save only a portion of the data. If you do not specify a
starting and ending point, the entire buffer data is saved. You may also specify the how you want the
time saved with the time format parameter.
You can append the contents of a reading buffer to a file that is already on the USB flash drive. When
you append data, you can specify the starting and ending point in the buffer to save only a portion of
the data and time format as you do when you save the buffer.
All readings are saved in the comma-separated value (.csv) file format. This format stores tabular
data (numbers and text) in plain-text form. You can import the .csv file into a spreadsheet. See the
following figures for an example of a buffer .csv file imported into a spreadsheet.
