3. Продукт бүтүп калдыview
The EARU Single Phase LCD Digital Energy Meter series offers various models (DDS662, DDS662-L, DDS663, DDS667, DDS668) designed for measuring electrical parameters. All models feature an LCD display and are suitable for 35mm DIN rail installation.
Model Variations and Features:
- DDS663, DDS662, DDS662-L: These models do not have a reset button. The temporary kWh reading cannot be reset to zero, and the total kWh reading is also non-resettable.
- DDS667, DDS668: These models include a button for operation. The temporary kWh reading can be reset to zero by holding the button for 6 seconds. The total kWh reading remains non-resettable.
- DDS668: This specific model is designed to always display two values simultaneously, with one of the displayed values always being power.

5. Орнотуу
5.1 DIN Rail Installation
The energy meter is designed for standard 35mm DIN rail installation. It can be directly installed into a household lighting distribution box.
5.2 Зымдарды туташтыруу ыкмалары
The meter supports two wiring configurations:
- Top Input and Bottom Output: Connect the incoming power lines (N and L) to the top terminals and the outgoing load lines to the bottom terminals.
- Top Output and Bottom Input: Connect the incoming power lines (N and L) to the bottom terminals and the outgoing load lines to the top terminals.
6. Операция
The meter provides various readings on its LCD display. Models DDS667 and DDS668 feature a button for cycling through display modes and resetting temporary values.
6.1 Дисплей функциялары
The meter can display the following parameters:
- Total Energy (kWh): Cumulative energy consumption, non-resettable.
- Temporary Energy (kWh): Resettable energy consumption (only for DDS667, DDS668).
- Real Voltage (V): Instantanous voltage.
- Real Current (A): Instantaneous current.
- Real Power (W): Instantaneous active power.
- Жыштык (Гц): Power line frequency.
- Power Factor (PF): Күч фактору.
6.2 Button Operation (DDS667, DDS668)
- Кыска басуу: Press the button briefly to cycle through the different display parameters (Voltage, Current, Power, Frequency, Power Factor, Total kWh, Temporary kWh).
- Узак басуу (6 секунд): For models DDS667 and DDS668, hold the button for 6 seconds to reset the temporary kWh reading to zero. The total kWh reading cannot be reset.
7. Техникалык тейлөө
7.1 Жалпы кам көрүү
- Keep the meter clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid exposing the meter to extreme temperatures, humidity, or direct sunlight for prolonged periods.
- Do not attempt to open or repair the meter yourself, as this may void the warranty and pose safety risks.
7.2 Маалыматтарды сактоо
The meter is designed to retain total energy consumption data even in the event of a power failure. This prevents data measurement errors and loss of accumulated readings due to unexpected power outages.
8. Кыйынчылыктарды
If you encounter any issues with your energy meter, please refer to the following common troubleshooting steps:
- Дисплей жок: Check the power supply connections to ensure they are secure and that the meter is receiving power.
- Туура эмес окуулар: Verify that the wiring is correct according to the diagrams in Section 5.2. Ensure the meter's rated voltage and current match your electrical system.
- Backlight Behavior (DDS667/DDS668): The backlight typically illuminates when a button is pressed and may dim or turn off after a short period to conserve energy. This is normal operation.

9. Колдонуучунун кеңештери
- Power Outage Маалыматтар: Rest assured that your total energy consumption data is saved even if there's a power loss. Only temporary kWh (on applicable models) can be reset.
- Temporary kWh Reset: For models DDS667 and DDS668, remember to hold the button for 6 seconds to reset the temporary kWh reading. A quick press will only cycle through display modes.
- Арткы жарык: The backlight on models with a button (DDS667, DDS668) is not continuously on. It activates when the button is pressed, which is normal behavior and helps save power.
