DDS353 Series,

Meter Type	Measurement
DDS353	kWh Total =Forward energy+Reverse energy
DDS353AF	KWh Total=Forward energy only
DDS353F+R	1 = kWh total ( forward + reverse) 2 = kWh (forward energy [import]) 3 = kWh (reverse energy [export])
DDS353F-R	1 = kWh total (calculated by forward - reverse) 2 = V (Voltage) 3 = A (Ampere - current load) 4 = W (Watt - current active power) 5 = Hz (Frequency) 6 = PF (power factor)
DDS353AI	1 = kWh total ( forward + reverse) 2 = V (Voltage) 3 = A (Ampere - current load) 4 = W (Watt - current active power) 5 = Hz (Frequency) 6 = PF (power factor)
DDS353FI	1=Forward energy only 2= V (Voltage) 3= A (Ampere - current load) 4= W (Watt - current active power) 5= Hz (Frequency) 6 = PF (power factor)
DDS353F+R+I	1 = kWh total ( forward +reverse) 2 = kWh (forward energy [import]) 3 = kWh (reverse energy [export]) 4 = V (Voltage) 5 = A (Ampere - current load) 6 = W (Watt - current active power) 7 = Hz (Frequency) 8 = PF (power factor)
DDS353F-R-I	1 = Total Kwh（Forward - Reverse) 2 = Forwarder energy display 3 = reverse energy display 4 = V (Voltage) 5 = A (Ampere - current load) 6 = W (Watt - current active power) 7 = Hz (Frequency) 8 = PF (power factor)
