Calculator Limitations
Calculator memory is an important factor to consider when collecting data with LabPro. Even though
LabPro can store up to 12,000 points, if a calculator has insufficient memory when using a “Get” request,
no data will be retrieved. Each element of a list, and therefore each data value takes up about 10 Bytes of
calculator memory (regardless of the calculator) and calculator programs also occupy memory. Each
calculator supported by LabPro has unique limitations on memory availability for program and data
storage and other limitations that may need to be considered while programming for LabPro. The table
below highlights some calculator features.
Calculator

data points**
TI-73 25 K No limit* 999* 2500
TI-82 28 K 6 99 594
TI-83 27 K No limit* 999* 2700
TI-83 Plus 24 K No limit* 999* 2400
TI-85 28 K No limit* 2800* 2800
TI-86 96 K No limit* 6000* 9600
TI-89 188 K No limit* No limit* 18800
TI-92 68 K No limit* No limit* 6800
TI-92 Plus 188 K No limit* No limit* 18800
*Number will vary depending on available memory.
**These numbers are approximate, are based on a free memory, using 10 Byte/data point standard. The
TI-82 is limited to 6 lists of 99 points/list.
