Error conditions
Error message “ E ” will appear on the display and further calculation
becomes impossible when any of the following condition occur.
1) You attempted to divide by 0
2) When allowable input range of function calculations exceeds the
range specified
3) When result of function calculations exceeds the range specified
4) When the [ ( ] key is used more than 13 levels in a single
expression
5) When USL
<
LSL value
To release the above errors, please press [ ON/C ].
Basic Calculations
Use MAIN ( [ MODE ] 1 ( MAIN ) ) mode for basic calculations.
Arithmetic calculation
Arithmetic operations are performed by pressing the keys in the same
sequence as in the expression.
