1. Producte acabatview
The Techbee Plug-in Electrical Meter Socket is an advanced device designed to help you monitor and manage your electricity consumption. It provides comprehensive data on various electrical parameters, allowing you to identify energy-intensive appliances and optimize your power usage for energy saving and environmental protection.

Figure 1.1: Techbee Plug-in Electrical Meter Socket Electricity Usage Monitor (Model JK-PM04) with its packaging.
Característiques principals:
- Energy-saving and Environmental Protection: Measures power consumption and calculates total energy costs for rational electricity planning.
- Multi-functional Monitoring: Offers 11 display modes including power (Watt), total energy used (kWh), carbon emissions (CO₂), voltage (Volt), current (Amp), frequency (Hz), power factor, cost per kWh, minimum power, and maximum power.
- Protecció multicapa: Features warning indicators (screen flash and LED) for preset power, energy cost, or consumption limits. Default overload limit is 3680W, with a recommendation to set it to 1800W for initial use.
- User-friendly Display: Large, easy-to-read display set at a 45-degree angle for optimal visibility.
- Partial Reset Function: Allows deletion of measurement data without affecting original settings (e.g., cost/kWh).
- Bateria incorporada: Retains settings and measured data even when unplugged.
2. Configuració i ús inicial
Follow these steps to set up your Techbee Power Meter:
- Desembalatge: Carefully remove the power meter from its packaging.
- Pel·lícula protectora: A transparent protective film is present on the screen. You may remove it for clearer visibility or keep it as preferred.
- Encès: Plug the meter directly into a standard electrical wall socket. The display should illuminate. If the screen remains blank or buttons are unresponsive, plugging it into a live socket will resolve the issue as it powers the internal battery and display.
- Initial Overload Setting: The default overload power limit is 3680W. Before using the energy meter, it is recommended to set the overload power to 1800W for general household appliances. Refer to Section 3.2 for instructions on setting alarm thresholds.
- Connecteu l'aparell: Plug the appliance you wish to monitor into the socket on the front of the power meter.

Figure 2.1: The meter features a large display and a built-in battery for convenience.
3. Instruccions de funcionament
The Techbee Power Meter features four control buttons: MODE, SET, UP, i ABAIX.
3.1. Modes de visualització
Premeu el botó MODE button to cycle through the 11 different display modes. Each mode provides specific electrical data:
- Watt / Total Cost: Displays current power consumption in Watts and accumulated cost.
- Total kWh Used: Shows the total kilowatt-hours consumed.
- Carbon Emissions (CO₂): Displays CO₂ emissions based on energy consumption.
- Voltage / Freqüència: Mostra el volum actualtage (V) and frequency (Hz) of the power supply.
- Current / Power Factor: Displays the current (Amp) and power factor.
- Cost per kWh: Permet configurar i viewing the cost per kilowatt-hour.
- Potència mínima: Shows the lowest recorded power consumption.
- Potència màxima: Shows the highest recorded power consumption.
- Alarma de sobrecàrrega: Displays the set overload power limit.
- Alarm of kWh: Displays the set kWh alarm limit.
- Alarm of Cost: Displays the set cost alarm limit.

Figura 3.1: Mésview of the 11 monitoring modes available on the device.
3.2. Setting Alarm Thresholds and Cost
To set specific values like cost per kWh or alarm limits:
- Premeu el botó MODE button until you reach the desired setting mode (e.g., "Cost per kWh", "Overload Alarm", "Alarm of kWh", or "Alarm of Cost").
- Premeu el botó SET button. The digit you can adjust will start flashing.
- Utilitza el UP i ABAIX botons per ajustar el valor.
- Premeu SET again to move to the next digit or to confirm the setting.
- Once all digits are set, press MODE per sortir del mode de configuració.

Figure 3.2: The device provides visual alarms (flashing LED and screen indicators) when set thresholds are exceeded.
3.3. Resetting Data
The meter allows for partial data reset, which means you can clear accumulated measurement data (like total kWh or total cost) without losing your custom settings (like cost per kWh or alarm thresholds). To reset measurement data, press and hold the ABAIX button for approximately 5 seconds until the relevant data clears.
3.4. Monitoring Appliance Consumption
The meter can precisely detect power usage down to 0.5W, allowing you to identify even the tiniest standby power consumption from your devices. This helps in tracking and reducing unnecessary electricity usage across various household appliances.

4. Manteniment
To ensure the longevity and accurate performance of your Techbee Power Meter, follow these maintenance guidelines:
- Neteja: Netegeu el dispositiu amb un drap suau i sec. No utilitzeu productes de neteja abrasius ni dissolvents, ja que poden danyar la pantalla o laasing.
- Emmagatzematge: Guardeu el mesurador en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
- Bateria: The meter includes a built-in Lithium Metal battery. This battery is not user-replaceable and is designed to retain settings and data when the device is unplugged.
- Eviteu la humitat: Do not expose the device to water or high humidity. It is designed for indoor use only.
5. Solució De Problemes
If you encounter any issues with your Techbee Power Meter, refer to the following common problems and solutions:
| Problema | Causa possible | Solució |
|---|---|---|
| Screen is blank or buttons are unresponsive. | Meter is not receiving power or internal battery needs charging. | Plug the meter into a live electrical socket. This will power the unit and charge the internal battery. |
| Display is difficult to read. | Lack of backlight in low-light conditions. | Use a flashlight to illuminate the screen for better visibility. Ensure adequate ambient lighting. |
| Overload alarm activates frequently. | Connected appliance exceeds the set overload limit. | Reduce the load on the circuit or adjust the overload limit if appropriate (refer to Section 3.2). Ensure the total wattage does not exceed the meter's maximum capacity (15A). |
| Data not resetting correctly. | Incorrect reset procedure. | Assegureu-vos que manteniu premut el botó ABAIX button for approximately 5 seconds to perform a partial reset. |
