Insert parentheses into formulas as required by the application.
To insert parenthesis:
U Press the +-*/... soft key repeatedly until parenthesis ( ) are shown
on the right of the screen
U Press the open ( or close ) parenthesis dimension key
Parentheses are combined with arithmetic operators, math functions,
constants and variables to define dimensions:
Units of measure
Dimensions acquire units of measure from channel functions,
dimension functions and constants used in their defining formulas. For
example, formulas containing numeric channel functions and numeric
constants will produce numeric dimensions without units of measure.
Parentheses in a formula.
Example:
A = (Pi*(C1exp2))/4
Where:
(C1exp2) is the quantity C1 raised to the second power
(Pi*(C1exp2)) is the entire numerator grouped as a single variable
for division.
If combining and mixing units of measure in formulas
violates standard math or physics conventions, type or
mismatch errors will be generated.
