126 Data Collection
configure itself using the first available sensor. Any sensor that is
already being controlled by a Data Collection tool is considered
unavailable.
Data Collection controls
The Data Collection tool controls available are:
Running an experiment and collecting data
1. When the desired sensor is connected and the Data Collection page
is set up as desired, press the Start icon ( ).
2. If Lists & Spreadsheet is on your page, you see each sample collected
populate the rows in the table. The sampling data points are plotted
on the graph.
3. When all data points are collected, Data Collection automatically
stops. If desired, you can press Stop ( ) prior to the end of the
experiment.
4. To rerun the experiment without retaining the current data, press
START ( ). The data displayed is erased when the new experiment is
started.
Data Collection names
The naming system for Data Collection data includes a group designator
and a member designator (group.member). For example, in a
temperature versus time experiment, the data is named run0.temp_C and
run0.time_s. Remember that TI-Nspireé computer software is case
insensitive: RUN0.TEMP_C and run0.temp_c reference the same set of
data.
