Screen Explanation
This screen appears when the LabPro is disconnected from the
calculator or when the LabPro loses power. When the LabPro and
calculator are reconnected, the calculator may not recheck the
sensor setup, and this error results.
Press
CLEAR
to reset the LabPro to initial conditions (In general,
whenever you see something on the screen that does not look
correct, press
CLEAR
to reset.), and then set up the channel again.
Or press
GRAPH
(On TI-89, TI-89 Titanium, TI-92, TI-92 Plus) to
recalibrate channels but retain data collection parameters.
These four screens usually appear when there is not enough
memory available in the calculator to collect any or all of the data
and then graph it. Reduce the number of data points you are trying
to collect.
Following are estimates of the number of data points that can be
collected if the calculator RAM memory has been reset prior to
sending DataMate to the calculator:

* This is the limit of the TI-82/83 Plus calculator list.
** For the TI-89 and 92 Plus, the first value is the number of
points that can be collected with 1.xx Calculator Operating
System; the second value is the number that can be collected with
2.03 calculator operating system. The 2.03 Operating System
optimizes the calculator memory; we recommend you upgrade to
the 2.03 (or higher) code. The latest code is available at:
http://www.ti.com/calc/docs/downloads.htm.
*** This is the limit of the TI-89/92 Plus calculator data variable.
Note: If you use DataMate’s curve fit option, the memory available
for collecting data will be less than that shown above because more
calculator memory is required for curve fitting.
Using a TI-89, TI-92 or TI-92 Plus, if the memory error occurs
because too many data points were attempted, you must go into
the memory management of the calculator and delete the "cbldata"
data var. Then restart DataMate and begin data collection.
Remember to reduce the number of points collected.
