Data Collection – Choose Data Collection from the
Sensors menu to set the data-collection mode and
associated parameters. The parameters listed will
depend on the mode selected. Data-collection
modes include Time Based, Events with Entry,
Selected Events, Photogate Timing, Full Spectrum,
Gas Chromatograph, Drop Counting, and Data
Matrix.
o Mode: Time-Based – Time-
ased data collection
is the default data-collection mode for most
sensors. In this mode, sensor readings are
recorded at regular time intervals.
Adjustable parameters for this mode include the
rate (or interval) and duration of data collection.
The total number of samples to be collected
based on these parameters will be displayed.
Warning Messages
Under some circumstances, the Rate and Duration fields may be highlighted in yellow or
red. The yellow warning indicates that the rate has been set to a value slower or faster
than what is recommended for the connected sensor, or that the number of samples
could lead to performance issues. You can still collect data using these settings;
however, you may have undesirable results.
The red warning indicates one of the following, and you cannot exit the dialog box until
the warning condition has been resolved:
The rate has been set to a value slower or faster than what a connected device
and/or sensor configuration can support
The number of samples exceeds the storage available
The number of samples exceeds 2000 (for rates faster than 80,000 samples/s)
