The raw data from an integer register read will not give the user a complete real-world value. A multiplier must be applied to the Integer register value to complete the information. The multiplier used to calculate the actual real-world value varies depending on the register being read and the CT size.
As stated in the register listing for the Energy Meter:
"For measured data, the float format registers are recommended. The Integer format registers can be difficult to use for the measured data, as a multiplier must be used for each one to get the correct value. Most of the multipliers change depending on the CT Size. Reading the float format registers avoids the need to use multipliers."
