The Custom Function screen is used
for applying simple or advanced
mathematical equations to a Task’s
Input value.
Press the “Functions” button to display
a list of available functions.
Scroll down the list and highlight
“h377c()” or “h377f()” in the list. Press
the “Insert Function” button to add
the function to the Custom Function
equation.
If no parameter or Task is specified
within the parentheses “()”, the Task’s
Input value (labeled as “RawValue”
under the User-Defined Tasks section)
will be used. In other words, h377c() is
equivalent to h377c(RawValue).
Press the “OK” button to save the
changes made to the “Custom
Function”.
Press the “OK” button on the “Math & Data Options” menu to return to the Analog Input properties
menu, and “OK” again to return to the “Edit Task” screen.
To add the “AirTemp” Task to the existing Log File, follow the steps outlined in Adding an Output.
