Product
ION7550/ION7650, ION8600, ION8800, ION8650, PM8000, ION7400, ION9000
Cause
The documentation does not describe what 1/2 Class System VA represents.
Resolution
1/2 class system VA refers to the VA's at half of the current class of the meter  (for class 20 it is @ 10 amps and for class 2 it is @ 1 amp)
For more information on the line loss calculation in ION meters, please refer to document 7EN72-0208
