5.3.08 Output Equations Menu

When Main Menu 1 is displayed, pressing a key adjacent to the Output Equations
item opens the Output Equations Menu, shown in figure 5-10.
The Output Equations menu is used to define more complex calculations on the
instrument outputs than are possible using the basic ratio and log ratio options. There
are two user-defined equations, Equation 1 and Equation 2, which take the following
form:-
⎛
Equation =
⎜
⎝
where the operator "±" may be set to either addition or subtraction, and the variables
A, B, C and D can be chosen from the following list:-
