How to read energy registers from a CM2xxx series meter?

Issue
How to read energy registers from a CM2000 series meter?

Product Line
CM2000 series meter

Cause 
Customer is having issues reading KWh via modbus registers 

Environment 
CM2000

Resolution
The CM2000 series energy is stored in 4 registers (except Incremental Energy, which is stored in 3 registers). These registers use the Modulo 10,000 format which uses the following formula:
R4*10,000^3 + R3*10,000^2 + R2*10,000 + R1

Details explaining Mod 10k as well as examples can be found in FA212766.

The CM2000 energy registers are listed below as a reference:
