anti-thermal deformation. Meter case is double insulation, its protection grade is IP54 (IEC60529).
Meter terminals are made of brass with nickel plated, which is suitable even for tropical climate.
Meter is equipped with sealable terminal cover.
Keypad prepayment Meter has two deduction modes: energy deduction mode and money
(amount) deduction mode.
Energy deduction mode:
Meter calculates consumption based on energy consumed (i.e. kWh). The credit recharged in the
meter is also energy (i.e. kWh).
Money (amount) deduction Mode:
Meter should be configured with tariff (flat tariff, TOU tariff or step tariff)first. Credit in the meter is
displayed as money amount. Balance amount will be deducted when every 0.01kWh is
consumed (i.e. 0.01kWh X tariff rate is the amount to be deducted every time) .
Money (amount) deduction----TOU tariff application instruction:
4 tariff rates and 12 time shifts can be programmed each day. According to electricity using

5.2 Weekly tariff
According to working day and weekend day, daily tariff codes for a week can be defined.
Weekly tariff defines effective day tariff table types on variety of occasions from Monday to
Sunday. The administrative department can store maximum 12 different weekly tariff tables. It can
set different daily tariff tables for every day of a week to differentiate each other (such as
difference between working day and weekend). It can also set the same daily tariff code to use
the same type of tariff.
There are 8 bytes for each weekly tariff. The first byte is the number of weekly tariff , while for
the last 7 bytes, each byte is in accordance with the number of daily tariff from Monday to
Sunday.
8X12=92 bytes in total.
5.3 Seasonal tariff
Based on the cost of electricity generation and the anticipation on the electricity market, different
weekly tariff adopted in each season can be defined.
Seasonal tariff defines the choices of weekly tariff table in practical use. Energy administration
department could define up to 12 seasonal tariffs in different periods and situations. So the
administration can work on the seasonal differences of tariff shift. The seasonal tariff table is
annually repeatable as the year factor is not taken into consideration. The simplest situation is
that there is only one weekly tariff number and the unique tariff number is used from January 1st,
(Seasonal tariff is like year time zone. State Grid demands 2 time zones in a year.)

Seasonal tariff table
Starting from Jan.1st, the starting date (Month and Date) of each season is the ending date
(Month and Date) of the last season. Sequence in ascending order is MM/DD.
4X12=48 bytes in total.
5.4 Holiday Tariff
In public holidays and festivals, the administration can select the particular daily tariff table in
special days. So the particular tariff forms holiday tariff.
Holiday tariff defines different daily tariff in public holidays and festivals. Meter can store up to 100
special days. For regular holidays (same day for every year, for example Jan 1st ), a special code
“A1H” can be set. In the host computer or HHU, MMDD can be set to show this day is valid for
every year. For the unfixed holidays (different day in different year, for example Easter Day or
Chinese Spring Festival), data should be input each year in the term of YYMMDD. Maximum 50
Festivals can be set in this type of meter as well as there are 50 tables in this meter. Estimated
validity period should be arranged and the time shifts of the festival tariff table should be modified
in practical use.
70 Shenzhen Inhemeter Co., Ltd
www: inhemeter.com Three-phase CT/PT Operated Keypad Energy Meter
The basic unit is 5 bytes, the first byte is the number of holiday tariff, the second, third and fourth
bytes are respectively YY/MM/DD of the holidays. The fifth byte is the number of daily tariff, all
5X50=250 bytes in total.

Every tariff is in correspondence with four tariff rates: forward active / reverse active / forward
reactive/ reverse reactive. There are 8 tariffs, and every tariff is in correspondence with four tariff
rates. Tariff rate consists of tariff code, forward active rate(four bytes) / reverse active rate(four
bytes) / forward reactive rate(four bytes) / reverse reactive rate(four bytes) . 8X（1+4X4）=136
bytes in total.
5.6 Confirmation of valid daily tariff
At 00:00:00 each day, the energy meter will select proper daily tariff number from Holiday Tariff
table, Seasonal Tariff table and Weekly Tariff table, then the daily tariff table of that day can be
selected to RAM from ERROM. (For the energy meter which RAM is relatively small, time Daily
tariff table of the present and the next period can be put in). At 0 second each minute, the energy
meter will process the period of daily tariff, according to the present daily tariff table, to conduct
tariff measurement control. It can be referred as follow:

5.7 Spare tariff
As the changes of resource and the energy supply, as well as electricity generation,
transportation and the electricity cost, tariff should be changed accordingly. Due to big quantity of
energy meters and the dispersion of locations, it’s impossible to modify the tariff for all meters at
the same time. In order to solve this problem, a set of spare tariff which is pre-stored in the meter
is applied.
Utility can set activation date for the spare tariff. When the spare tairff is activated, meter will start
to use new seasonal, weekly, daily and holiday tariff. After activation, the previous tariff will be no
73 Shenzhen Inhemeter Co., Ltd
www: inhemeter.com Three-phase CT/PT Operated Keypad Energy Meter
longer valid. In such way, utility can upload spare tariff to meters and on activation date all meters
will excute new tariff.
Spare tariff and its activation date will be saved temporarily in the meter, after activation, the old
tariff information will be deleted and meter will be able to accept another set of spare tariff.
5.8 Step Tariff Measurement Function (Optional)
DTZ1513 Three phase CT/PT connected energy meter can define different step tariff rate
according to monthly consumption. The step tariff rate consists of units as follow:

5.9 Tariff Data Settings
The tariff (holiday tariff, seasonal tariff, weekly tariff, daily tariff and spare tariff) can be
programmed by the tariff setting software organized by the R&D Center of INHEMETER. After
setting and confirmation, communication data module will be generated in accordance with
energy meter’s communication protocol, and data can be loaded to the meter through follows:
A. Infrared (HHU or PC) local setting
B. RS-485 communication port (HHU or PC) local settings
C. Remote batch setting
When it is not factory settings (such as on site modification or user preference):
A: To modify tariff and electricity rate by local communication, operator needs to turn on the
programming switch (with seal protection), which needs password authentication.
B: To modify tariff and electricity rate by remote communication, operator must go through
authorization and password authentication via data management center, it can also go through all
or selected meter type/meter No. to modify the tariff and electricity rate in batch mode. Meanwhile
meter must be allowed in remote programming mode.

8.3 Load control function
DTZ1513 CT/PT connected prepayment keypad meter has load control function.
The load control function of DTZ1513 CT connected prepayment keypad meter complies with the
load control algorithm method specially mentioned in SCSSCAAA9 item 7.7.2 of Eskom.
Notice: Meter load control function cannot be used to protect load security protection. It is
normally used to control the users average load upper thresholdin a associated area. (mainly
concerned with grid security, cable loss reduction and power supply cable load limit). Load
connected to CT/PT means primary winding load
(Transformation ration algorithm)
Automatic delay recovery mode after over load power off.
A. If one phase load is beyond load threshold value 132.000kWh (OBIS code 21.35.0 data
item), the alarm will sound and LED indicator will flash, and LCD on MCU/CIU will display
overload information, and switch to display on real time present overload phase power.
Above 2 LCD display by shift, which means it is in overload status and current load is 140.80kW.
B. If the consumption load is beyond load threshold for more than 45 seconds, the built-in relay
will cut off power at 45th second. After 150 seconds, the relay will connect automatically (power
supply will not work during the 150 seconds). And LCD on MCU/CIU will display remaining time
for power recovery (unit: second; it means remaining lock time. The remaining lock time will
reduce by a second interval).
If the user does not low down the consumption load, which is beyond threshold value, above
process will repeat (Power off- Delay recovery- Power off).
C. Within 30 minutes, if tripping occur for 5 times, meter will cut off power supply and last for 30

A: After finishing the test before installation, installation operation and circulation status check
after installation, the pre-stored electricity can be reset to zero by installation worker before
officially handing over to users.
Carry-out ways: In the stage of installation, while registering user and meter information in the
power vending system, the system will generate the TOKEN code specialized in clearing up
power consumption credit. After finishing the circulation check status and before officially handing
over to users, installation workers will input this TOKEN code into keypad prepayment energy
meter to clear up power consumption credit (clear up pre-stored electricity).
B: After completing measurement meter testing, installation and inspection of electricity
circulation status after the installation, energy meter can be formally delivered to users in the prior
record by a meter installer residual value of the stored power to submit the sale of electricity
management system.
Specific carrying out ways: After completing measurement meter testing, installation and
inspection of power after the installation, energy meter can be formally delivered to users in the
prior by a meter installer record residual value of the stored charge and get the user to confirm it;
installer will record the pre-stored electricity meter to log on to the remaining value of the stored
power management system for the sale of electricity from the sale of electricity management
system in the user when the first purchase deducted.
C: Give the pre-stored power to users for free.
Since the quantity of pre-stored electricity is not very big, then it can be given to users for free use
after energy meter test, installation and circulation statuses check.
D: The pre-stored power will be deducted with one time by power vending management system.
According to pre-stored power in the energy meter before delivery, power vending management
system will deduct it while users open an account and purchase the power.
20.3 Load threshold presetting
The purpose of pre-set load threshold is to facilitate measurement test before installation of
energy meter. According to the user information and load threshold permitted by utilities, the
special load threshold TOKEN code will be generated by the power vending management system,
and then users input it into related energy meter to finish load threshold setting.
In the process of using the meter, if the actual load of users changes, then they can apply for load
threshold change anytime. If the application is authorized, the specific TOKEN code used for load
threshold will be generated by power vending management system, then users input this TOKEN
to the related meter and finish load threshold changes.
