Upgraded Watt Power Meter Plug Home Electrical Usage Monitor Consumption, Energy Voltage Amps Kill Tester with Backlight, Overload Protection, 7 Modes Display

This power meter plug can monitor power (W), energy (kWh), volts, amps, hertz, power factor, cost, minimum and maximum power (W), cumulative days, and time for various appliances. By switching among 7 display modes, you can conveniently view different parameters while an appliance is running. The home energy monitor can calculate and display the power consumption of an appliance and the estimated electricity cost over cumulative time.
Enhanced LCD Display: Featuring a large 2.36 inch x 1.85 inch screen with a clearer backlit monitor, this electrical usage meter presents data clearly and is easily readable day or night. The 180° wide viewing angle is excellent for reading and recording data from any position, eliminating the need to stand directly in front of or bend over to view the numbers.
Adjustable Backlight Time: This upgraded watt meter provides 5 backlight time options. The default duration is 10 minutes (bL-0). To change the backlight time, press and hold the "UP" and "DOWN" buttons simultaneously to enter the setting, then press "UP" or "DOWN" to choose the desired time (bL-0 = 10 minutes, bL-1 = 1 hour, bL-2 = 4 hours, bL-3 = 8 hours, bL-4 = always on). Finally, press the "COST" button to save the setting.
Overload Protection: When the connected appliance's power exceeds the set overload limit, the LCD will show "OVERLOAD" as a warning. All buttons will become inoperative until the load power is reduced or removed. The default overload power is 3680W and is adjustable from 0 to 3680W. It is generally recommended to set the overload power to 1800W before initial use. To enter the setting, press the "function" button for more than 3 seconds.
Data Memory Function: This wattage meter retains power consumption data even when unplugged from the socket or when appliances are disconnected from it. The last recorded data is immediately visible upon the next use. This function also automatically saves data in case of a sudden power outage.
Monitor Your Energy Usage: This watt meter power analyzer helps track electricity consumption and manage power usage to potentially lower bills. It functions as a voltage, kilowatt, current, and electricity meter
