Save/Load
DataMate allows you to save experiments in LabPro’s FLASH Memory,
recall them later, and delete them when you no longer need them. An
experiment includes all program set-ups, sensor selections, calibrations,
graph settings, and so forth, as well as any data you have collected. Heart
Rate Monitor and Respiration Monitor data, as well as data collected in
Single Point mode, are not saved with experiments because DataMate
calculates the readings.
NOTE: This feature is not available for the TI-83 and TI-83 calculators.
