Features: - Power consumption of the Power Meter Monitor: 0.5 W -Operating voltage: 230VAC -Frequency display: 50HZ -Operating current: max 16A -Wide voltage range: 230V-250V - Wattage (Watts) display is 0W~9999W; but the actual power display (Watts) is 0~3680W -Timing display range: 0 seconds ~ 9999 days -Voltage display range: 0V~9999V -Current Display (Amps): 0.000A ~ 16.000A -Frequency display: 0Hz ~ 9999Hz -Price display range: 0.00COST/KWH¡ «99.99COST/KWH -Total KWh and cost display: 0.000KWh-9999KWh, 0.00 COST----9999 COST Overload alarm: When the current exceeds 16A or the power exceeds 3680W, the "overload alarm" symbol flashes. When the captured power value is less than 1.0W, it is regarded as local power consumption and time is not accumulated. Working Current: ≤ 16A Measurement accuracy: ± 2% Packing List: 1 * Power Meter 1 * User Manual 1 * Screwdriver Safety Alert Function - The LCD display shows overload warning. You can set a power alarm value. When the power exceeds the set value, exceeds 3680W or the current exceeds 16A, the “OVERLOAD” icon will flash on the LCD to warn the user that the family is protected. Electrical safety, which is very useful for reducing energy consumption and ensuring safety. Multi-function socket - monitoring device power (w), accumulated energy consumption (kwh), accumulated electricity costs (COST), carbon dioxide emissions (KgC02), days of electricity (DAY), voltage (V), ampere (A) and power factor (POWER FACTOR), AC frequency (Hz) and minimum and maximum power, ideal for energy monitoring in household appliances. Monitor energy consumption and currents in real time based on daily consumption records to ensure adequate power consumption, saving you energy and money. Two abs methods - single rate mode and dual rate mode can be set according to the instructions. The double rate is generally used for time division. Data hold function - With the memory data hold function, you can disconnect the device from the electricity meter or remove the electricity meter of the socket. The last data is saved, and the meter can be moved and displayed without losing any data. Note: The data is manual measurement, please allow 1-119cm error, due to the differences between light and screen, there will be a certain color difference, the specific received in kind prevail.
