* This is the limit of the TI-82, TI-83 Plus, and TI-83 Plus Silver
Edition calculator list.
** This is the data variable limit for these calculators. You must
have Operating System (OS) version 2.05 or higher. The
latest OS is available at education.ti.com/softwareupdates.
If using a TI-89, TI-92, TI-92 Plus, or Voyage 200 PLT and a
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.
This screen usually appears when the user is running
DataMate and one of the DataMate subprograms has
been deleted from the calculator memory. All of the
subprograms must be present in order for DataMate to
function properly. (All related programs begin with
"DATxxxx.")
Reset the RAM on the calculator, then transfer the
DataMate program from CBL 2™ to the calculator and
begin again.
This screen appears on a TI-83 Plus calculator when one
of the variables accessed by the DataMate app has been
archived in the calculator memory. These variables are:
lists: L1 - L11, list C, list M
real: A - Z
matrix: [A]
string: Str0 - Str6
Go into Memory Management and unarchive any of the
above variables.
Note: For the TI-89, TI-92 Plus, and Voyage™ 200 PLT, to
unarchive any variable press

You have attempted a calculation outside the valid
range. The most common cause of this error is trying to
perform a power curve fit on Time Graph data. In Time
Graph, DataMate collects a data point at time x=0. When
the curve fit equation tries to divide by the 0, this error
occurs.
The easiest way to correct this is to use the SELECT
REGION option to eliminate the x=0 point from the
graph. Then try the power curve fit option again.
