and plug the meter into the USB port. Open the software, press SETUP
on the meter, go to Com Port(C) and select Com3(M).
To import and view the data, go to DataLogger(D) at the top of the
window and this will open a new window. The words Accepting data

disappear when the transfer is complete. You will notice that there is no
information on the graph. This is because you have not selected the data

On the left hand side of the DataLogger window you will see three
columns that have the headings Set, DATE and TIME. Highlight the row
of information you wish to view in blue by clicking on the row once.
With the row still highlighted, double click on the row and the data you

To display information in each of these boxes, double click on any part
of the graph once to display a green line and double click again on a
different part of the graph (must be to the right of the green line) to display
a blue line. The green line is CursorA and the blue line is CursorB. By
using these cursors it allows you to focus on a sample of all the data
recorded and find out information about the sample in the boxes below
the graph.
CursorA 46.2 @ 03:51:03 displays the time and sound of the recorded
data where CursorA is positioned.
CursorB 62.6 @ 04:09:13 displays the time and sound of the recorded
data where CursorB is positioned.
Max.Between A and B 70.7 @ 04:02:23 is the maximum sound detected
by the meter between the two cursors and the time at which this sound
was recorded.
Min.Between A and B 40.5 @ 03:57:43 is the minimum sound detected
by the meter between the two cursors and the time at which this sound
was recorded.
Avg.Between A and B 45.962 is the average from all the data between
the two cursors.
To remove the cursors, press Undo Zoom or double click somewhere
else on the graph where you would like CursorA to be moved to. You
can also use the cursors when zoomed in on part of the graph, but this
can only be done after you have zoomed in on the point you wish to view.
If you try to zoom in after you have placed the cursors on the graph or
zoom out with the cursors on the graph they will disappear and have to
be placed on the graph again.
