The TI-73, 82, 83, 85 only have enough memory available to load one of the Vernier program groups at a time. The TI-86, 83+, 89, 92, 92+, Voyage 200 have enough memory available to load all three programs. If your calculator is currently full, you will need to clear out some of the memory before loading the programs.

If you are using a TI-89, TI-92+, or Voyage 200, there is an additional concern with using all of these programs on your calculator. If you switch back and forth between ChemBio, Physics, and DataMate you will need to do the following between switches:

  1. Press F6
  2. Choose 1:Clear a-z
  3. Press Enter

This will clear several of the variables the programs use and force the next program you run to start from scratch. This is only necessary when switching between DataMate and ChemBio or Physics.
