5. Measurement
This meter is designed to measure two types of energy:
z Import active energy
z Reverse active energy
Dual tarrif measurement on both import active and export active. Import active and reactive
measurement +A=+A -A=|-A|。
Store import and export energy data of 12 months.
z Tarrif: 2 tarrif
z Tarrif schedule: 8 tarrif schedules, each have 16 time frames max.
z Week table：Max 12 week types, in each week type, it can be appointed with tarrif from
Monday to Sunday.
z Season table：Max 12 season types. Each season can be appointed with week type that
needs to be used in this season.
z Holiday： Max 120 holidays. Each holiday can be appointed with tarrif that needs to be
used in this holiday. Among them, public holiday can be appointed as special holiday and
annually periodic holidays.

7. Display mode
This meter is designed with two display modes:
z Normal scrolling display
z Power outage display
Normal scrolling display
Under this display mode, LCD shows import active and export active energy in
each 8 seconds. Details as below:
Total import active： 000 T1+T2

T1 import：001 T1
T2 import：002 T2
Total export：010 T1+T2
T1 export：011 T1
T2 export：012 T2
Power outage display
When power supply is not available, meter can display import active energy.
Such display mode is realized by meter’s back-up battery.
8. Back-up battery
This meter is equipped with high quality lithium back-up battery. Back-up
battery is used to keep LCD display when power supply is not available. This
battery is tested and installed inside the meter in the factory. For safety
consideration and in order to keep the battery working in a good condition,
meter should be installed where is far away from heat-emitting household
compliance, such as stove. When the battery is in low voltage condition,
will be shown on LCD as indication.
9. LED Indication
LED is available for the meter. LED is on to indicate the meter is connected to
power supply and it flashes to indicate energy consumption.
10. Self Diagnostic
10.1 Reverse Energy
This meter is designed with reverse energy detection functionality. Once the
8 / 18
Single Phase Electronic Meter
reverse energy is detected, the symbol will be shown on LCD. The
reverse energy indication will disappear once the reverse energy event is
removed.
Note: The power threshold of reverse energy is 5% of Un*Ib. When reverse
energy exists, and the current power exceeds the power threshold, then this
event will be detected as reverse energy.
10.2 Meter Malfunction
This meter is designed to be able to detect meter’s parameter error and
hardware error. Below is segment displayed on LCD indicating detected error.
Parameter error will be displayed such as E10 or E20 or E30 in decimal.
When parameter or hardware error is detected, error indication will be
displayed on LCD. After error is removed and the meter is repowered, the
indication will disappear automatically.
11. Installation
11.1 General Consideration
Meter should be installed correctly as it could determine meter’s functionality
and lifespan. Please follow the prescribed procedures carefully.
When selecting a suitable position for the meter, the following should be
considered:
General safety consideration in case of possible electric shock, fire, etc.
For safety consideration, and avoid damage to the meter, install the meter
where is far away from any water tap.
Keep the energy meter away from a stove or any house hold compliance
which produces heating exceeds meter’s limited heat withstand.

11.2 Meter Handling
When handling this meter, please avoid the following actions:
Avoid drop meter during the installation.
Make sure meter is installed where is arid and ventilated.
Do not attempt to open the meter cover.
Do not add any additional or external voltages to the meter other than what
is specified by the supplier.
11.3 Meter Connection
Please follow the instruction to arrange the wire connection:
a) Use copper cable as the lead-in wire to terminal block.
b) Screw out the wire-fasten screw so that the connection wires can be
inserted into.
c) Remove the plastic cover of the connection wire long enough so that the
wire-fasten screws can contact each connected wire.
d) Screw the wire-fasten screws to fix the connection wires.
e) Pull the connected wires to check whether they are connected tightly.
NOTE: The screws in the terminal block should be screwed down tightly to
avoid burnt because of bad contact or thin lead-in wire.
Terminal wiring diagram is as below.
