Logger Pro only allows the importing of “approximate” data from the family of calculators including the TI-89, TI-92, TI-92 Plus and Voyage 200. To ensure that Logger Pro will be able to import data from your calculator, the calculator must be set to approximate mode. To set your calculator to approximate mode:

  1. Press [MODE].
  2. Move the cursor down to Exact/Approx……
  3. Move the cursor to the right to expand the menu of choices.
  4. Move the cursor to 3:Approximate.
  5. Press [ENTER] twice to save the change.

The DataMate program will automatically set your calculator to the approximate mode.
