Measurement display interface description：
1. Under measurement status, press “ ”/ “ ”to switch display of 3 phase phase voltage, 3 phase current, 3 phase
active power, 3 phase reactive power, 3 phase appearance power, 3 phase power factor, total power, frequency etc
2. Press “ ”/ “ ” increase or decrease key to switch display of total active power, forward active power, backward active
power, total reactive power, forward reactive power, backward reactive power.
3. DO1, DO2 are used as the alarm output status indication in the alarm mode, and the switch output status indication is
made in the "remote" mode of the switch quantity.
4. COM flashing means communicate is acting.
5. P(Kwh) means Total Active Energy (algebraic sum of forward active energy and backward active energy); Q(Kvarh)
means Total Reactive Energy (algebraic sum of forward reactive energy and backward reactive energy).
