Main highlights

Various monitoring parameters: the socket can monitor the power (W), energy (kWh), volts, amps, hertz, power factor, cost, minimum and maximum (W), cumulative days and time of your devices. By switching 8 display modes, you can easily know the different parameters during the operation of the device. The electricity meter can also calculate and show how much electricity your devices use and how much electricity bill it costs in the cumulative time.
Premium material: The entire body of our wattage meter is made of high-quality PC material, which makes our electricity meter socket more durable. The standard DE socket and the plug are suitable for all DE standard devices.
Overload protection: the standard overcharge power is 3680 W. When the power of the device exceeds the overcharge power, the LCD displays "overload" and emits a "beep" to warn the user. All buttons lose their function and can only be reactivated once the overload alarm has been fixed by increasing the setting value or removing the device.
KWH alarm settings: you can set a power consumption limit and when the accumulated power consumption reaches the set value, the kwh meter socket will output a "beep" stronger, and the "KWH" arm flashes continuously to alert the user. If you want to silence the alarm, you can set a higher power consumption limit or reset the power consumption limit (Note: reset will clear all settings).
Data storage function: the socket tester will record your power consumption data when you remove the ammeter socket from the socket or remove devices from the socket electricity meter. All setting data and cumulative data (electricity quantity, cost, unit price) are stored. You can see the last data directly the next time you use the energy meter (without current, voltage, power, power factors). This function can also automatically save the data when there is a sudden power failure.
Backlight: With white backlight and black numbers, the LCD display of our power consumption meter socket can display the data clearer and help you read the data that is easier day and night. The backlight only lights up when the ammeter is connected to AC connection. You can set the time for the screen to turn off automatically or press the "Down" button to manually turn the backlight on and off.
Adjustable backlight time: Our electricity meter socket has 5 options for backlight. The default backlight time is 10 minutes (bL-0). If you want to change the backlight time, you press the "Up" and "Down" button at the same time to enter the background time setting, and then press "Up" and "Down" to select the backlight time (bL-0 =10 minutes, bL-1=1 hour, bL-2=4 hours, bL-3=8 hours, bL-4=Always off), finally press the "Set to set the backlight time settings.
