• Multiple Monitoring Parameters: This plug-in power meter features 6 modes to monitor power (W), energy (kWh), volts (V), current (A), and costs (€). Use the power meter to identify the largest electricity consumption and reduce energy costs.


Figure 2: Six Monitoring Modes. This diagram illustrates the six different parameters the power meter can monitor: Power (W), Cumulative Power Consumption (kWh), Voltage (V), Cumulative Electricity Costs (€), Current (A), and Electricity Price (€/kWh). An example of the meter plugged into a wall socket with an appliance (oven) is shown.

• 180° Rotatable Display: The electricity meter's display can be rotated forwards, backwards, or horizontally to achieve any angle. Even if sockets are installed in very high/low positions or narrow corners, values can be easily read. This power meter socket adapts to various installation scenarios, saving you from neck strain or bending down to view дысплей.

• Лёгкае кіраванне: Two simple buttons make operation easy – no need to worry about complex instructions. The energy cost meter comes with an easy-to-understand instruction manual in German.
• Функцыя памяці: The plug-in power meter automatically saves data in case of a sudden power failure or disconnection between the socket, power meter, and power supply. Upon restart, the last saved data is reloaded to prevent data loss.
• Data Deletion and Reset: Press the reset button to clear accumulated data (kWh, costs), while retaining the price setting. Use a stylus (not a needle) to press the RESET button and avoid damage.


Figure 5: Data Storage and Reset. This image illustrates the power meter's data storage capability, showing how it retains consumption data even when unplugged. It also points out the location of the recessed reset button, which requires a stylus to operate.

• Папярэджанне аб перагрузцы: The preset overload threshold is 3680 W. If the power exceeds this limit, "ENERGY OVERLOAD" flashes on the display. For safety reasons, immediately switch off the device. This power meter is an ideal choice to save energy, electricity, and money.

3. Настройка

Setting up your MECHEER Plug-in Power Meter is straightforward:

1. Распакуйце: Carefully remove the power meter from its packaging.
2. Падключыць: Insert the power meter into a standard electrical wall socket.
3. Падключыць прыладу: Plug the appliance you wish to monitor into the socket on the front of the power meter.
4. Пачатковы дысплей: The display will light up, showing the current power consumption (W) or the last recorded data if the memory function is active.

The device is designed for immediate use with minimal setup required.

4. Рэжымы працы

The power meter features two simple buttons: "MODE" and "RESET" (recessed). The "MODE" button allows you to cycle through the various monitoring displays:

• Магутнасць (Вт): Displays the instantaneous power consumption of the connected device in Watts.
• Энергія (кВт·г): Shows the cumulative energy consumed in kilowatt-hours.
• Вольт (В): Паказвае бягучы томtage крыніцы харчавання.
• Ток (А): Displays the current drawn by the connected device in Ampэрэс.
• Costs (€): Shows the cumulative cost of energy consumed based on the set unit price.
• Unit Price (€/kWh): Дазваляе вам view and set the cost per kilowatt-hour.

Setting the Unit Price

To set the unit price for cost calculation:

1. Press the "MODE" button repeatedly until the display shows the "€/kWh" mode.
2. While in this mode, use the "UP" button (often integrated with MODE or a separate button, refer to device markings) to adjust the unit price. The setting range is 00.00 €/kWh to 99.99 €/kWh.
3. The device will automatically save the set price.

5. Кіраванне дадзенымі

Функцыя памяці

The power meter is equipped with a memory function that automatically saves accumulated data (kWh and costs) even if there is a sudden power failure or if the device is unplugged. When power is restored, the last saved data will be reloaded, preventing data loss and ensuring continuous monitoring.

Скід даных

To clear the accumulated data (kWh and costs) while retaining the set unit price, locate the recessed "RESET" button on the device. Use a stylus or a non-sharp, pointed object (do not use a needle) to gently press this button. This will reset the cumulative readings to zero.

6. Safety Warnings and Tips

Папярэджанне аб перагрузцы

The power meter has a preset overload threshold of 3680 Вт. If the power consumption of the connected device exceeds this limit, the display will flash "ENERGY OVERLOAD". For your safety and to prevent damage to the device or connected appliances, immediately switch off the overloaded device.

Агульныя парады

• Avoid excessive rotation of the display to prevent cable breakage or internal damage.
• Data can only be read when the wattmeter is properly connected to a live electrical socket.
• The electrical socket records kWh data only when the device's operating power exceeds 0.3 W. Devices consuming less than 0.3W may not have their energy consumption accurately recorded.

8. Выпраўленне непаладак

• Дысплей пусты: Ensure the power meter is securely plugged into a live electrical socket. Data can only be read when the wattmeter is connected to a socket.
• Data not accumulating for low-power devices: The electrical socket records kWh data only when the device's operating power exceeds 0.3 W. For very low-power devices (e.g., standby mode), the consumption might not be registered.
• "ENERGY OVERLOAD" flashing: This indicates the connected appliance is drawing more than 3680 W. Immediately unplug the appliance and use it with a power source that can handle its load, or reduce its power consumption.
• Display rotation feels stiff or makes noise: Avoid excessive rotation of the display beyond its intended range (180° horizontal, 90° vertical) to prevent internal cable breakage.
• Reset button not working: Ensure you are using a stylus or a non-sharp, pointed object to press the recessed reset button. Do not use a needle or sharp object that could damage the internal mechanism.
