7 Monitoring Modes: This energy meter socket monitors multiple parameters including time, cost, accumulated energy consumption (kWh), voltage (V), frequency (Hz), current (A), power factor, minimum and maximum power (W), and the unit price of electricity to help monitor device usage. Memory and Backlight Function: Automatic data backup in case of power failure. The date can be retained for up to 90 days; however, instantaneous data such as voltage is not saved. After plugging in the device, press any button to activate the backlight for 10 seconds. The large LCD display ensures easy reading. Overload Protection and Safety: "OVERLOAD" flashes on the LCD screen when the connected load exceeds 3680W or 16A, and the power consumption socket will automatically cut off power. Users should check the load and reconnect after resolving the issue. Easy to Use: Press the "FUNC" button to select monitoring modes, the "COST" button to set the electricity unit price, and the "UP" and "DOWN" buttons to adjust the unit price. The "RESET" button clears all settings, including the unit price. Precision and Real-Time Monitoring: Designed with professional accuracy and quality construction, this energy meter provides reliable energy consumption readings. Real-time monitoring helps reduce electricity waste, supporting energy and cost savings.
