Defining a Math Function
Select and highlight a blank line – they are numbered 1 through 60 - in either
Default or Current File math and then click on the ‘Change’ button. This will
bring up a window showing the different types of calculations available.
Interpreter includes a range of pre-defined functions to simplify performing
Math operations. For more complex calculations Interpreter includes the
Expression Evaluator, where users can enter the expression or function that
they wish to calculate.
Whether using the Expression Evaluator or the pre-defined functions, it will be
necessary to select one or more Source (input) channels. Clicking on the
‘Select’ button next to each source channel will bring up a list of all available
channels, not just those in the currently logged file.
After choosing the Source channel and selecting any other options, choose
the result channel. Again, a list of all channels is displayed after clicking on
the ‘Select’ button. Care should be taken to select a channel with appropriate
units for the result.
