l Account settling function: 6 kind of settling data, settling time and method can be programmed.
l Communication function: built-in modulated infrared communication interface. GPRS, RF, RS485, RS232, modulated and non-modulated infrared communication interface are optional
Other functions
l Load profile: the average active energy, reactive energy, instant active and reactive energy etc can be recorded separately or assembly
l Event record: the meter can record the happening time and times of losing phase, missing voltage/current, unbalance, voltage deviation and current reversing.
l Cover opening record: this type of meter can record opening time of terminal cover and upper-cover automatically.
l Meter can record time of important event such as power on/off, MD resetting, programming time etc.
l Load control and safety alarm: inner relay will cut off power and buzzer will alarm in the condition of over-load.
