Customizing data collection
You can start recording data using the default settings, or complete one or more
of the following tasks to change the sampling rate or sampling mode.
Setting the sample rate
With the SPARK in periodic sampling mode (the default mode), complete these
steps to set how many data points are recorded each second or how much time
elapses between data points:
1. Touch the Sampling Options button.
The Sampling Options screen opens.
2. Touch the Sample Rate Unit: box and select Hz, seconds, minutes, or
hours.
3. Touch the Sample Rate: box and select a value.
4. Touch OK.
Putting the SPARK into periodic sampling mode
In periodic sampling mode (the default mode, sometimes known as
“continuous” mode), the SPARK records data points at regular intervals. If the
SPARK is in manual sampling mode, complete these steps to put it into periodic
sampling mode:
1. Touch the Sampling Options button.
The Sampling Options screen opens.
