MECHEER Power Meter Plug Instruction Manual

1. Introduction

The MECHEER Power Meter Plug is an advanced electricity usage monitor designed to help you track and manage the power consumption of your home appliances. This device provides detailed insights into various electrical parameters, enabling you to identify energy-intensive devices and optimize your electricity usage.

It features a large, clear LCD display with adjustable backlight, multiple display modes, and built-in overload protection, making it a versatile tool for energy monitoring.

2. Safety Information

WARNING!

• DO NOT use this device in a wet environment.
• DO NOT connect the power meter to a multi-plug outlet to measure multiple electrical appliances simultaneously, as this may cause the total power to exceed the threshold of 1800W and result in a short circuit.

NOTICE:

• Consumption and time will NOT be measured or counted when your device is in standby or not working, or if the rated power of your device is smaller than 0.5 watts. However, energy consumption is always measured once the device is plugged in.
• The device saves electricity quantity, cost, electricity price, and cumulative time. It does NOT save current, voltage, power, or power factors.
• If there is an abnormal display or no response, reset the electric meter by pressing the RESET button.
• The power of electrical appliances connected to this device must not exceed 1800W.

5. Operating Instructions

The MECHEER Power Meter Plug offers 7 display modes to monitor various electrical parameters. Use the FUNCTION and COST buttons to navigate through these modes and settings.

5.1. Display Modes

Press the FUNCTION button to cycle through the 7 display modes:

Figure 5.1: Overview of the 7 display modes available on the power meter.

1. Mode 1: Time/Watt/Cost Display - Shows cumulative time, current power consumption (Watts), and estimated cost.
2. Mode 2: Time/Cumulative Electrical Quantity Display - Shows cumulative time and total energy consumed (kWh).
3. Mode 3: Time/Voltage/Frequency Display - Shows cumulative time, current voltage (Volts), and frequency (Hertz).
4. Mode 4: Time/Current/Power Factor Display - Shows cumulative time, current amperage (Amps), and power factor.
5. Mode 5: Time/Minimum Power Display - Shows cumulative time and the minimum recorded power (Watts).
6. Mode 6: Time/Maximal Power Display - Shows cumulative time and the maximum recorded power (Watts).
7. Mode 7: Time/Price Display - Shows cumulative time and allows setting the electricity price. You can access Mode 7 directly by pressing the COST button.

5.2. Setting Electricity Price (Mode 7)

To calculate the cost of electricity, you need to set the price per kilowatt-hour (kWh).

1. Press the COST button to enter Mode 7.
2. Use the UP and DOWN buttons to adjust the electricity price per kWh.
3. Press the COST button again to save the setting.

5.3. Adjustable Backlight Time

The backlight duration can be customized to suit your needs.

1. Press and hold the UP and DOWN buttons simultaneously for a few seconds to enter the backlight time setting. The display will show "bL-0" and flash.
2. Press UP or DOWN to select the desired backlight time option:
   
   • bL-0 = 10 minutes (default)
   • bL-1 = 1 hour
   • bL-2 = 4 hours
   • bL-3 = 8 hours
   • bL-4 = Always on
3. Press the COST button to save the backlight time setting.
4. To manually turn off the backlight, press the DOWN button.

5.4. Overload Protection

The device features overload protection to prevent damage. The default overload power is 3680W, but it is recommended to set it to 1800W for typical household use.

1. To adjust the overload power, press the FUNCTION button for more than 3 seconds.
2. Use the UP and DOWN buttons to set the desired overload threshold (0 to 3680W).
3. Press the FUNCTION button again to save the setting.

When the power of the connected appliance exceeds the set overload threshold, the LCD will display "OVERLOAD" to warn the user. All buttons will become unresponsive until the load power is reduced or removed.

5.5. Data Memory Function

The power meter automatically saves cumulative data (electricity quantity, cumulative cost, cumulative time) even when removed from the socket or during a sudden power failure. This allows you to view the last recorded data when you use it again.
