Main functions
1. Display and indication: It adopts a large screen LCD with
abundant graphics and hint text. The displayed contents can be
scrolled automatically or by button, and the displayed items can be
configured as per the requirements. It is with backlight. Meter can
be read during power outage.
2. Measurement: It can measure voltage, current, active power,
reactive power, apparent power, power factor, import and export
active maximum demand, and four quadrant reactive maximum demand.
It is with high accuracy. Class 0.2S, Class 0.5S or Class 1 for kWh
are available.
3. TOU: 4tariffs; Built-in 2 sets of time zone tables and 2 sets of
daily period tables, which can be configured as per the
requirements. The switching time for both 2 sets of time zone
tables and 2 sets of daily period tables can be set to achieve the
mutual switching. It can be set 14 time intervals and 254 holidays.
4. Data snapshot: It supports freezing which include daily
freezing, hourly freezing, occasional freezing, immediate freezing.
5. Event logs: It can separately record latest 10 times events,
such as power outage, programming, time correction, meter cover
open and terminal cover open, reset of events, reset of meter, etc.
6. Communication interface: The meter has one far infrared
interface, one RS485. Interfaces are independent.
