3 Terms and definitions
For the purpose of this document, the following terms and definitions apply.
of materials with good transparency, and the transparent window and enclosure
shall be tightly bonded.
4.3.3 Terminals and terminal covers
The wires and terminals shall be secured in such a way as to ensure adequate
and permanent contact to prevent loosening and heat generation. All parts in
each terminal shall be guaranteed to be in contact with any other metal
component with minimal likelihood of corrosion. Terminals that are assembled
together and have different potentials shall be protected against accidental
short circuits. The electric energy meter shall have an independent sealable
terminal cover. The inside of the terminal cover shall be provided with a clear
and permanent wiring diagram, indicating the name and function of each
terminal. The terminal cover shall have sufficient insulation performance and
mechanical strength. Each terminal, screw holding the conductor, and outer or
inner conductor shall not be in contact with the terminal cover.
4.3.4 Buttons
The buttons shall be flexible and reliable; if there is a programming function,
there shall be corresponding measures to prevent unauthorized personnel from
operating.
4.3.5 Nameplate
The outer surface of electric energy meters shall have a nameplate. The
nameplate shall contain the manufacturer's name or trademark, instrument
model, year of manufacture, rated voltage, calibration current, meter constant,
accuracy grade, etc. The mark shall be clear and prevent UV radiation (above
level 7) without fading.
4.3.6 Output interfaces
4.3.6.1 Electric energy test pulse output
The electric energy meter shall have electrical pulse and optical pulse test ports
that are proportional to its electric energy. The electrical pulse shall be output
after opto-isolation, with a pulse width of 40 ms ± 10 ms. The optical pulse uses
LED as power pulse indication. The electric energy test pulse output shall be
accessible from the front.
4.3.6.2 Clock signal output
It is used to test the accuracy of the electric energy meter, and the output
frequency is 1 Hz.
d) The number of electric energy display digits is 8 digits, the factory default
is 2 decimal places, and the unit of measurement is kWh. The number of
decimal places can be selected by programming in 0 ~ 3.
