Energy Measurement The meter can measure both forward and reverse energy. Total energy data displayed by LCD, the display format XXXXXX.XX kWh, and store energy data of last 1 to12 month.
Demand Measurement The meter can measure active demand, display format XXXXXX.XX kW, and can store last 12 months demand data. Demand interval can be set from 1 minute to 60 minutes; slide time can be set from 1 to interval time. When slide time equals demand interval, demand calculation method use interval type.
Tariff Control: Support 1, 2, 3, 4 Four Tariffs, Support Any Programming Tariffs And Time Periods, Support Special Tariff Setting For Public Holiday Period. Maximum Setting 80 Public Holidays; 30 Time Zones in One Year; 16 Tariff Periods in One Day.
Communication: Support two communication modes: Near infrared and micro-power wireless (RF).
Users can use the RF and near-infrared mode to complete the meter data reading, parameter setting functions. RF is applied in the AMI system, connecting the meter to the terminating network, for users to use the AMI master station system remote data collecting, parameter settings.
Communication protocol complied with IEC62056-21; DLMS/COSEM.
Transportation and Storage
Energy meter transport and unpacking should not be subject to severe impact, and should according to GB/T15464-1995 “Instrumentation packaging technology” to transport and store.
Inventory and storage should be placed in the original packaging; stack height should not be more than five. Storage place should be kept clean, environment temperature 0℃～40℃. No more than 85% relative humidity, and should not contain corrosive gases.
