Brackets
Brackets can be used in formulas to change the priority of the operation.
Example: sqrt(@101/2+@102); (@201+@202+@203)/3

* priority determines the order of operations in the formula (the highest priority
is 0)
Notes
•
All analog values should be scaled before making calculations;
therefore, it is very important to fill the
Raw Min, Raw Max, Scale Min,
Scale Max
fields with Normalized values that are used in calculations.
•
After editing the formula, the program automatically validates this
formula and shows the result in the status area. If the formula is
incorrect, the background of the edited formula is changed to pink and
an error message is displayed in the status area.
•
By clicking on the
button, a new formula row with default settings
is added.
By clicking on the
button, the selected formula row is removed.
