- Positive/reverse active power, positive/reverse apparent power,
reactive power in 1,2,3,4 quadrants and active/reactive power in A,
B, C phase which can be measured. It can set tagged words of
active/reactive combination, aim at positive/reverse active power
and reactive power in 4 quadrants, to restructure active
combination, reactive combination 1 and reactive combination 2.
- All power can be time-share measured by total and max 4 tariffs.
(No time-share measurement for power in A, B, C phases)
- It can storage power data for 12 settlement period.
- For positive/reverse active power, positive/reverse apparent power,
reactive power in 1,2,3,4 quadrants and
active/reactive power in A, B, C phases, the valid range is
0~999999.99, and unit is kWh or kvarh.
Ø For active combination, reactive combination 1 and reactive
combination 2 power, the valid range is –799999.99~799999.99, and
unit is kWh or kvarh.

- It can set solution for 2 time zones, 2 daily periods and switching
time (yy/mm/dd/hh/mm) of both two.1st time zone and daily period
solution is default selection, when reach switching time of time
zone, it changes to 2nd solution of time zone, and when reach
switching time of daily period, it changes to 2nd solution of daily
period. Then set switching time again for 2 solutions,when reach
switching time of time zone, it changes to 1st solution of time
zone, and when reach switching time of daily period, it changes to
1st solution of daily period. Switching time would be clear since
changes of time zone solution and daily period solution.
- Max 4 tariffs. Each time zone solution can set 14 time zones as
max, with starting time and meter number of daily period which is
used. Each daily period solution can set 8 daily periods as max, 14
periods per day, with starting time and tariff which is used.
Minimum interval of periods is 15 mins., and period interval is
larger than actual demand cycle valve, can be set over 00:00.
Public holiday can be set, including date and daily period meter
number of each public holiday.
- Weekend holiday can be set, which controlled by tagged word, daily
period meter number can also be set for each weekend holiday.
- If the same for public holiday and weekend holiday, daily period
meter number of public holiday will be used.
- Automatic changeover of century calendar, time, leap year.
- If tariff number in the period of daily period is larger than
tariffs, or the tariffs is 0, the power in the period reckon in

No device inside can be adjust by user.
When installing and using, there should be tight enough for each
connection line, to avoid from any bad connection which would cause
heating to damage the meter. Make sure of the right connection of
input and output. Please install the meter on local where is dry
and ventilated. Don’t put in the place under direct highlight,
especial for infrared window. When using infrared communication, it
should take more attention to avoid from any disturb from highlight
to infrared interface, and please adjust the distance and angel of
infrared, to make sure of reliable communication.
＊ Use only isolated tools.
＊ Place the meter only in dry surroundings.
＊ Make sure the used wires are suitable for the max current the
meter can measure.
＊ Make sure the AC wires are installed correctly before activating
＊ Do not touch the meter connecting clamps directly with your bare
hands, with metal, blank wire or other material as you will have
the chance of an electricity shock and a possible chance for health
＊ Make sure the protection cover is placed after installation and
has been sealed.
＊ Installation, maintenance and repair should only be done by a
＊ Never break the seals or open the front cover as this might
influence the functionality of the meter.
＊ Do not through, drop, kick or other physical violence to the
meter as there are high precision components inside that will break
or make the meter measure inaccurate.
＊ Do not mount the meter in area's with harm gas, dust, mildew or
insects or on unstable surfaces.
