When the detected power value is less than 1.0W, it is regarded as the local power consumption, and the time is not accumulated. Operating Current: 16A Measurement Accuracy: 2% Packing List: 1 * Power Meter 1 * User Manual 1 * Screwdriver Safety Alarm Function - LCD Overload Warning. The battery alarm value can be set. When the power exceeds the set value, exceeds 3680W or the current exceeds 16A, the OVERLOAD icon will flash on the LCD screen to inform the user that the house is protected. Safe use of electricity is very helpful to reduce energy consumption and ensure safety. Multi-function socket - monitoring equipment power (w), cumulative electricity consumption (kwh), cumulative electricity cost (cost), carbon dioxide emissions (KgC02), working day electricity consumption (DAY), voltage (V), ampere ( A) and power factor (POWER FACTOR), AC frequency (Hz) and minimum and maximum power, ideal for monitoring energy in household appliances. Real-time monitoring of energy consumption and flow based on daily consumption records to ensure reasonable energy consumption, saving you energy and money. Two alternatives can be configured according to the instructions - single rate mode and dual rate mode. Double rate is often used for time division. Data Retention - Memory data retention allows you to disconnect the device from the meter or unplug the meter from the outlet. The latest data is saved, and the counters can be moved and displayed without data loss.
