Syn ERROR
Ma ERROR
Go ERROR
Ne ERROR
Stk ERROR
Meaning
1 Calculation formula contains an error.
2 Formula in a program contains an error.
1 Calculation result exceeds calculation
range.
2 Calculation is outside the input range of
a function.
3 Illogical operation (division by zero, etc.)
4 Poor precision in Σ calculation results.
5 Poor precision in differential calculation
results.
6 Poor precision in integration calculation
results.
7 Cannot find results of equation calcula-
tions.
1 No corresponding Lbl n for Goto n.
2 No program stored in program area Prog
“file name”.
• Nesting of subroutines by Prog “file name”
exceeds 10 levels.
• Execution of calculations that exceed the
capacity of the stack for numeric values or
stack for commands.
Countermeasure
1 Use or to display the point
where the error was generated and cor-
rect it.
2 Use or to display the point
where the error was generated and then
correct the program.
1234
Check the input numeric value and cor-
rect it.
When using memories, check that the
numeric values stored in memories are
correct.
5 Try using a smaller value for
∆
x (x incre-
ment/decrement).
6 Try changing the tolerance “tol” when
using Gauss-Kronrod Rule or the num-
ber of divisions “n” when using Simpson’s
Rule to another value.
7 Check the coefficients of the equation.
1 Correctly input a Lbl n to correspond to
the Goto n, or delete the Goto n if not
required.
2 Store a program in program area Prog
“file name”, or delete the Prog “file name”
if not required.
• Ensure that Prog “file name” is not used to
return from subroutines to main routine. If
used, delete any unnecessary Prog “file
name”.
• Trace the subroutine jump destinations
and ensure that no jumps are made back
to the original program area. Ensure that
returns are made correctly.
• Simplify the formulas to keep stacks within
10 levels for the numeric values and 26
levels for the commands.
• Divide the formula into two or more parts.
