Screen
Explanation
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the variables accessed by the DataMate app has been
archived in the calculator memory.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.
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.
The calculator tried to draw a graph but was not able to use
the window settings. This problem can occur if you collect
data and the data does not change (for example, the
temperature does not change). If DataMate tries to autoscale
the graph of this data (which it usually does), the calculator
may not be able to set the y-axis scale.
Press Íto quit. Press pand set the x-axis or y-axis
scales, making sure that the maximum value exceeds the
minimum. Then press sto draw the graph again.
This screen can appear when running DataMate on a
TI-89/92/92 Plus. It is caused by a loss of communications
between the calculator and the CBL 2 and usually means
there is a problem with the link port on the calculator.
Check that the cable is securely connected to the calculator
and the CBL 2. Then restart the program.
