6.
Start the test.
Click on “Start” to begin the test.
7.
Pause / Resume.
You can use this field to pause the test whenever desired, for example to
not include an event or time period in the Dosimeter test period.
The Dosimeter results may be stored in a memory, or recalled to examine a previous test.
Sound Study Graph
The Sound Study Graph function graphically displays the SPL level over a period of time. Use
this function to analyze noise levels over time, or to record concert or PA sound levels. It can run
in peak or average mode, and any of the A, C, octave-band or 1/3 octave-band filters may be
selected. The time can range from 1 minute to 24 hours. When the function runs, it divides the
time period into 120 equal divisions, sampling the sound level at each period. The SP395
computes either the average or peak SPL for that period, and draws a bar on the graph. This
continues until the total time for the test has expired.
As the function is running, the LEQ is computed and displayed. After the graph is complete, the
full LEQ is displayed, and stored with the graph. The graph can then be stored in one of the
memories, if desired.

The following fields and parameters are displayed in the Sound Study Graph test screen.
1.
Test Function
– Shows the selected test function.
2.
LEQ
- The accumulated LEQ (time-average SPL) is displayed in this field. When a test
is complete, or when a memory is recalled, this field shows the overall LEQ for the entire
graph.
3.
RMS/Peak Mode
- Switches between running the test in RMS average mode or in
absolute peak mode.
4.
Saves - Automatic Memory Save.
If desired, set the number of automatic memory
saves. This is the number to the left of the word “Save.” When multiple saves are
