Solution 11255: Troubleshooting Error 1 Message on the BA II Plus™ or BA II Plus™ Professional.

Why did I receive an Error 1 message on the BA II Plus or BA II Plus Professional?

The Error 1 message that appears is a result of an overflow. Check the following causes to determine what information was input incorrectly:

1) Attempted a calculation whose result is outside the range of the calculator i.e. (9.9999999999999E99).
2) Attempted to divide by zero (May occur in an internal calculation by the calculator).
3) Attempted to compute 1/x when x is zero.
4) In the statistics worksheet, attempted a calculation when all X values or Y values are equal.

Please see the BA II Plus or BA II Plus Professional guidebooks for additional information.
