Measuring Function
On the EM537’S front panel, there are three LED, active/reactive energy pulse light, and alarm indicator lights .
Meter can measure import active energy , export active energy , four-quadrant reactive energy. solar wattmeter
With time-division measurement function, user can store or calculate active and reactive energy according to the time interval of4 tariffs ( T1, T2, T3, T4).
Demand function
The meter can calculate the forward and reverse active/reactive demand and the demand occurrence time.
Data store function
The meter can store total active energy, forward/reverse active total energy and time-sharing energy. Also include the reactive forward/reverse total energy and time-sharing energy, four-quadrant reactive total energy and time-sharing energy.The meter can store current and previous 12months data.
tou function
The internal clock circuit of energy meter has time automatic switching function. Calendar, clock and rate can be set and adjustment through RS485, infrared interface. At least 4 tariffs and 12 time interval can be set within a natural day
Electricity parameters measurement and monitoring
The meter can measure: voltage, current, active power, reactive power, apparent power,power factor and frequency of each phase. Also can display the direction of the current and power. The resolution of frequency is 0.01Hz. the accuracy of Voltage,current,activepower,reactive power and apparent power is 1%.
Summer/winter time switch permit/prohibition
Smart meter provide automatic summer/winter time switch accomplished at 02.00 on the last Sunday of March(forward 1 hours) and at 03:00 on the last Sunday of October(back 1 Hours).
Communication Function
With an infrared COM and a RS485 COM. Its physical layers are independent with each other.The meter can realize data acquisition, broadcast time setting, read, program and manage through hand-held terminals, data acquisition terminal, test equipments and computers.
Alarm function
When the meter connect wire wrong example: current reverse, lost phase and reversed phase sequence , the meter will display , the ALARM led will be on.
U1 U2 U3
The missing letter means no voltage connection on that phase. The blinking letter means the voltage connection are not correct.
I1 I2 I3
The missing letter means no current connection on that phase
-I1 -I2 -I3
means the current connection is reversed
