The Formulator
The Formulator allows you to make data calculations on test data and on the results of other
Formulator calculations. The Formulator provides a variety of computational functions, common
mathematical operators, and common constants. Some of these may be used for real-time, in-test
calculations for test data. Others can be used only for post-test data computations. Clarius
automatically inserts the Formulator calculation results into the Run worksheet, in addition to the raw
data.
A formula created by the Formulator is an equation that is made from a series of functions, operators,
constants, and arguments.
A formula created using the Formulator calculates any combination of the following:
• Test data.
• Secondary data created by other Formulator formulas.
• Standard constants from the list of constants.
Formulator functions may be limited to specific sets of data. For example:
• Some of the functions operate on only on Run tab columns of values (vectors) only.
• Some operate on single values (scalars) only.
• Some operate on both single values (scalars) and columns of values (vectors).
The results of some calculations may be a column of values (vector) in the Analyze Run worksheet
tab or a column that contains only a single value (scalar).
Configure Formulator calculations
The Formulator allows you to do simple in-test calculations on test data and complex post-test data
calculations. You can use the following operators and functions for in-test, real-time calculations on
test data:
• Operators: +, -, *, /, ^
• General functions: ABS, SQRT, EXP, LOG, LN, DELTA
A variety of other functions may be used for post-test calculations. Refer to
Formulator function
reference (on page 6-228).
