Measuring function:
Consumption indication
On the EM535’S front panel, there are five LED, respectively, for the Active energy pulse light, current reverse ,Phase L1/L2/L3 . The constant of the impulse is shown on the nameplate of the meter
Pulse output
Smart din rail energy meter is equipped with a pulse output which is fully separated from the inside circuit. That generates pulses in proportion to the measured energy. They are test pulse output (pins 20 & 23). Usually, the test pulse output is used as testing accuracy or reading purpose in close quarters.
Communication port
Smart meter has equipped communication port, we can program the meter’s operation data or reading via these 2 ports.(Pin26 pin27) . There are two options for the communication com,RS485 or M-bus.
