If Product A is 87 octane and Product C is 92
octane, subtract Product A from Product C to find
the range. In this case, the range is 5. Take .5 (the
normal tolerance requirement) and divide it by
5. Multiply the result (.1) by 100 to find the
percentage of error the dispenser must maintain to
achieve the octane rating required for the blended
product. See the calculations in Figure 7.9 to arrive
at this number.
12. Use the information in the "How to Calculate Error
Range" illustration to calculate a new blend error
range percentage.
13. To change the setting, use the 0 through 9 buttons
on the keypad to enter a new blend error range.
NOTE: If an error is made, press the correct
number. The new number replaces the
error.
