What are Parameter Units and why do I need to set them?

Parameter Units are used by Enviro Data for comparison to regulatory limits and the unit conversion feature. (Unit conversion allows you to determine the target units for a conversion during import or reporting.) You can associate one reporting unit or Parameter Unit for each combination of a parameter and matrix.

For use with Regulatory Limits, the Parameter Units (and the matrix) must be the same as the units (and matrix) of the limits you are checking against.

They are also used during import checking, the Validation module, and in some reports.

You can view and edit Parameter Units by going to the EDITOR's Setup section, clicking on Manage Lookups and then clicking on Parameters.This will open the PARAMETERS form seen below. You can select the parameter desired in the Go to Parameter dropdown. Both the Matrix and Parameter Units can be set by using dropdowns in the appropriate text box. Note that both the Matrix and Units chosen must be present in their appropriate lookup table.

 In order to have these work with you data, make sure you also set Unit Conversion in the Display Options form as shown below.
