Issue: 
Customer  would like to check whether the displayed and recorded meter data is scaled and what the scaling is. 

Product Line:
ION8650 Meters

Environment:
Power Metering

Resolution:
There are two sets of scaling factors implemented to scale the PT/CT parameters: one is the PT/CT ratio in the Power Meter Module, while the other is the PT/CT ratio in the Factory Module. The Factory Module's PT/CT ratio will only be used to scale data if the PT and CT ratios in the Power Meter Module are both 1:1. There is a framework in the meter, referred to as SOV (Scaled Operational Value), that validates the above condition.
The attached documentation describes which measurements in the ION8650 are scaled and how:
