The sample rate is controlled with a list on the toolbar. The actual sample rate
that is achieved depends on the features that are enabled and the type of probe.
The actual sample rate may also vary depending on the speed of the computer
and how busy it is performing other operations. The Sam/Sec label indicates the
actual sample rate.
Avoid other tasks during data logging, or the sample rate may vary.
Irregular time stamp intervals in the recorded data can occur if this is
ignored.

The Zoom-Out button becomes active after data has been recorded or data has
been loaded from a file. To view the data after a recording session, click the
Zoom-Out button. The graph is capable of displaying a maximum of 32,000 data
samples. To view data in excess of 32k samples, the data needs to be saved to a
file. The data will be saved in multiple files of 32k samples each. These files can
be individually loaded for later viewing.
To use the Zoom-In function, click the Zoom-In button, then click the graph and
hold down the mouse button. Drag the mouse pointer down and to the right to
select the area, and then release the button when the appropriate area is
selected. The Zoom-In function only zooms the horizontal axis, not the vertical.
Click the Scatter-Graph-Live button to return to viewing live probe data.

To use this feature, select the View menu and enable Moving Average. The
Moving-Average-Box will display on the main screen. Enabling Moving
Average changes the log function to record one sample per second over the
selected time period (for example, a six-minute average will average and record
360 data samples). Click the Log icon to measure and record the time-based-
exposure to EMF. An elapsed timer will display the time of exposure along with
the moving average. The Elapsed Time label will flash when the selected time
interval is reached.
