Source: Inepro Metering 'PRO380 Series user manual' V2.18, appendix 3.2 (Modbus register map); older V1.14 register numbers are still served by the meter but are not modelled here. Every value is an IEEE-754 single-precision float read with function code 03 (ABCD word order). Power registers are in kW/kvar/kVA and are scaled to W/var/VA; energies are already in kWh/kvarh. A 120 ohm resistor across terminals 22/23 may be needed on a short test bus."
