Read Levels
Click on a graph to place a cursor.
For single measurements, the cursor shows dB levels for all visible parameters and time information. The time inform-
ation is the measurement start with the total measurement time (in parentheses).
For logged measurements, the cursor shows dB levels for all visible parameters and time information. The time inform-
ation is the time at which the cursor is placed and the logging interval (in parentheses).
✐ Note:
l You can view frequency analysis data for the time at which the cursor is placed in the Spectrum view
l For long measurements, measurement data will be down-sampled to display the entire logging profile in the win-
dow. This means that the logging interval will be scaled 10, 100 or more times depending on the length of the
measurement and the logging interval used. When you zoom in on the profile, the scale of the data will auto-
matically adjust
You can use the left and right arrow keys on your keyboard to move the cursor or click on the time readout in the lower
graph and enter a specific time to jump to that time.
Select a Range
In either of the graphs, click and drag to select a range.
You can adjust the boundaries of the range by clicking and dragging the left or right cursor in the lower graph.
Zoom
There are many ways to get a closer look at your data:
l In the large graph, click on a measurement number to zoom in on the measurement
l Select a range, then right-click and select Zoom. Select Unzoom to zoom out
l Double-click the y-axis to scale the graph to the shown levels
Hint: When you zoom in, you can use the overview to stay oriented within the project.
