Command 4 - Conversion Equation Setup
{ 4, Equation Number, Equation Type, Number Format, Constants }
Equation Number
* 0 Clear All equations.
1 Equation 1 (Channel 1)
2 Equation 2 (Channel 2)
3 Equation 3 (Channel 3)
4 Equation 4 (SONIC channel)
*1
Polynomial: Input constants in sequence, from n = 0 to 9.
*3
Input of zero for constants can be skipped if all remaining constants are not used.
•
When the conversion result of the "conversion equation" selected by Command 4 causes an overflow, the EA-200 sends a result of zero (0) to the calculator.
