Users now have the ability to use formula evaluation to configure complex uncertainty budget component calculation scenarios (i.e. some calculations involve more than one measurement parameter or posses conditional logic).Uncertainty budget formulas can use the following operators and variables:


Mathematical operators
Multiply       * 
Divide         /  
Add            + 
Subtract      -

Math functions
Pow(x, y)  - raise a number "x" to a power "y"
Sqrt(x)      - return square root of "x"

Exclusion condition operators
Less than             < 
Greater than        > 
Less or equal      <= 
Greater or equal >=
Equal                  == 
Not equal           !=
Conditional AND   && 
Conditional OR      ||
Variables
Measurement Point - variable from current measurement point
@Nominal
@Mean

Navigate to your uncertainty budgets by clicking 'Administration' from the main menu bar then 'Sites'. Next, click the site name that your budgets are for. Next click 'Uncertainty' from the left side of the screen.


Once here, select a budget you would like to modify. 

Next, click into the 'Uncertainty Component' tab to add or edit the components of this uncertainty budget.

Once in the component, input your formula in the 'Uncertainty Evaluation Formula' field. Utilize the '+' to add in variables to the equation.
