Measuring function:
he smart energy meter is equipped with 6+1 LCD display, which is used as recording consumption and can’t be reset to zero. The number system is based on units of 10. And unit is kWh.
Another way through RS485 and PC software or HHU(hand held unit)unit can read power consumption
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 24 & 25). Usually, the test pulse output is used as testing accuracy or reading purpose in close quarters.
The test pulse output is a polarity dependant, passive transistor output requiring an external voltage source for correct operation. For this external voltage source, the voltage (Ui) should be 5-27V DC, and the maximum input current (Imax) should be 27mA DC. To connect the impulse output, connect 5-27V DC to connector 25 (anode), and the signal wire (S) to connector 24 (cathode). The meter pulses is indicated on the front panel.
CT rate setting
On the smart meter display appear: CT followed by the currently memorized value .With the set key, you can move the cursor to the right .
