This macro enables you to ignore the uncertainty values that you have entered for your references (support devices and/or piston gauges) in COMPASS for Flow. This macro allows you to specify your reference uncertainty (in % Reading and/or % Span) according to ranges of flow. This correlates to having different standards for different ranges of flow.
See the below Word document for the macro code that can be pasted into a new Global macro in COMPASS for Flow software.
