features the high precision, small size and simple installation. It integrates the measurement of all
electrical parameters with the comprehensive electricity metering and management provides
various data on previous 48 months, checks the 31st harmonic content and the total harmonic
content. It is fitted with RS485 communication port and adapted to MODBUS-RTU .ADL400 can
be used in all kinds of control systems, SCADA systems and energy management systems. The
meter meet the related technical requirements of electricity meter in the IEC62053-21standards.

7.1 Measurement
It can measure the electrical parameter,include U、I、P、Q、S、PF、F、1~31th harmonic。
If：U = 220.1V，f = 49.98Hz, I = 1.99A，P = 0.439kW
Such as:U = 220.1V，f = 49.98Hz, I = 1.99A，P = 0.439kW
7.2 Calculating
Can measure the active energy、forward active energy、reversing active energy、forward
reactive energy、reversing reactive energy。
7.3 Timing
Two timing table，four time zone，one table have fourteen timing，four rate。
7.4 Demand
The description about demand:
Table 3 Demand description list
Demand
The average power in the demand cycle.
Maximum
demand
The maximum value of demand in a period of time.

- 6 -
Slip time
A recurrence method to measure the demand from any time point
during a period shorter than the demand period. The demand
measured by this means is called sliding demand. The recurrence
time is sliding window time.
Demand
cycle
The time period between two same average value of demand.
The default demand cycle is 15 minutes, slip time is 1 minute.
The meter can measure 4 kinds of maximum demand: forward active, reversing active,
inductive reactive, capacitive reactive maximum demand and the occur time.
7.5 History data statistics
The meter can record last 48 months or last 90 days history energy in each tariff.

Note:
1 All the display menus above are in the model of ADL400 three phases four lines with
multi-tariff rate function and can be changed by the keys.
2 There will not be power or power factor on each phase and will only show total power and
power factor (Active, reactive, apparent) under the three phase three lines.
3 There will not be date, time, maximum demand and energy by time without the function of
multi-tariff rate.
8.3 Key Menu
Keep press at any main menu and get in “PASS” interface, and then press
show “0000”, and enter the code. If you enter a wrong code, it will show “fail” and back
to main menu; and if you enter a right code, you can set the parameter. After setting the parameter
and keep press , it will show “save” and save the change by pressing in “yes” interface
and quit without save by pressing in “no” interface.

9 Communication description
The meter adapts MODBUS-RTU protocol, and the baud rate can be chosen from 1200bps、
2400 bps、4800 bps、9600bps and 19200 bps. The parity is None.
The meter needs shielded twisted pair conductors to connect. Customers should consider the
whole network’s parameters such like communication wire’s length, the direction, communication
transformer and network cover range, etc.
Note:
1、Wiring should follow the wiring requirements;
2、Connect all the meter in the RS485 net work even some do not need to communication,

- 12 -
which is benefit for error checking and testing;
3、Use two color wires in connecting wires and all the A port use the same color.
4、No longer than 1200 meters of RS485 bus line.
