www.vernier.com for all the info you need. Please look at the new 12 bit
Lab Pro using data logger software. You can also visit www.ti.com. The
CBR and CBL2 need a graphing calculator, such as the 83/83+ (73,86,89,92
also). The Data Pro doubles as a CBL2 and a "ULI" interface for laptops.
All is menu driven with very clear language. The big plus is that its
footprint is non-existent, as opposed to a desktop and it can be carried
anywhere......................CBL2/Lab Pro/83+ also have Flash memory, so
when Vernier/Texas Instruments design an inprovement, you simply download
the new base code and have a un-to date tool. That alone is worth the
price of admission. The calculators have menus in five or six different
languages as well. All programs to run the CBR/CBL2 are available at both
sites.
good luck and enjoy. Email off line for more info or help.
(There is info at both sites for "overseas" sales.)
