CBL Interfacing
Calculators
We recommend using the TI 82 or a more recent,
similar model, the TI 83 when setting up a Calculator Based Laboratory.
The TI 85 and TI 92 can also be used with much of the probeware
discussed on this forum, but the facilitators are less familiar
with their use at this time. Therefore the following discussion
is limited to the TI 82/83.
TI-82 Graphics Calculator
The TI-82 is suggested for use with the CBL. Two features make
it better suited for this environment:
- It displays the lists in a spreadsheet manner, which allows
you to easily look at and edit more than one list at a time; and
- The trace mode in the 82 allows you to read individual data
points when they are displayed on the screen.
Neither of these features are available in the TI-85.
The TI-82 calculator is fully compatible with the CBL system.
Programs entered on the calculator control the data gathering
process on the CBL. The calculator also supports interactive graphical
analysis and data analysis features, including data input of up
to 99 entries in six lists, eight regression models, and four
types of data plots. It is also possible to split the screen,
displaying both a graph and a data table.
TI-85/CBL Graphics Calculator
This calculator contains programming commands making it compatible
with the CBL. Note, however, that it lacks several features the
TI-82 has (above). The calculator provides access to more lists,
with the length of the lists limited only by the available memory.
