4.14 User Variables

Eight Flex Control Parameters are available as general purpose variable storage. They are named UserVariable1

through UserVariable8. The User Variables Window is used to document and manually specify the value of each

user variable. If a lookup table output value is mapped to one of these user variables, then the lookup table output

value will overwrite the user variable in this tab. User variables can also be selected as inputs to the lookup tables. It

is important that the user variables not be selected as both lookup table input parameters and output parameters.
