Introduction
This user manual provides comprehensive instructions for the AMTAST Power Consumption Monitor (Model AMF050M). This device is designed to accurately measure and display various electrical parameters of connected appliances, including power consumption, voltage, current, and cost. It features a clear backlight LCD display and built-in data memory for convenient energy management and cost analysis.
Key Features
- Comprehensive Monitoring: Measures power (W), energy (kWh), volts (V), amps (A), hertz (Hz), power factor, maximum power (W), time, and days. This allows for detailed tracking of electricity usage, which is crucial for understanding and managing electricity bills.
- Backlight LCD Display: Equipped with a large, clear LCD display (45mm x 70mm) with a blue backlight for easy reading, even in low-light conditions. The backlight activates when the meter is connected to AC power.
- Data Memory Function: Features a built-in 3.6V rechargeable battery that retains stored power usage data during power outages, ensuring continuous tracking and allowing data retrieval once power is restored.
- Overload Protection: Includes an overload protection function that alerts the user if the connected appliance's power consumption exceeds the safe capacity, enhancing safety.
- Ease of Use: Simple plug-and-play operation. Connect the monitor to a wall outlet and then plug your appliance into the monitor to begin tracking energy usage.
- Cost Calculation: Calculates electricity expenses based on cumulative kWh usage, providing a clear overview of energy costs.
Setup Guide
Initial Setup
- Unpack the Device: Carefully remove the Power Consumption Monitor from its packaging.
- Connect to Power: Plug the monitor directly into a standard 110V 60Hz US wall outlet. The LCD display should illuminate, and the backlight will activate.
- Internal Battery Charging: The internal rechargeable battery will begin charging automatically. This battery maintains data even when the unit is unplugged.
- Plug in Appliance: Connect the appliance you wish to monitor into the receptacle on the front of the Power Consumption Monitor.

Setting Cost per kWh
To accurately calculate electricity expenses, you need to set the price per Kilowatt-hour (kWh):
- Press the COST button to enter cost setting mode. The current cost per kWh will flash.
- Use the UP and DOWN buttons to adjust the value.
- Press the COST button again to confirm and save the setting.
Resetting Data
To clear all accumulated data (time, kWh, cost, min/max power), press and hold the RST button for approximately 5 seconds until the display resets to zero.
Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
- Storage: Store the monitor in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: The internal rechargeable battery is designed for long life. For optimal performance, ensure the unit is occasionally plugged in to allow the battery to charge.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or not lighting up. | Not properly plugged into an active outlet. | Ensure the monitor is securely plugged into a live 110V 60Hz US outlet. |
| Display is difficult to read. | Viewing angle is off; backlight is off (if on battery). | Adjust your viewing angle. Ensure the unit is plugged into AC power for backlight activation. |
| Readings appear inaccurate. | Incorrect cost setting; appliance drawing very low power; external electrical interference. | Verify the cost per kWh setting. Ensure the appliance is drawing sufficient power for accurate measurement. Test with another appliance. |
| Data not saving after unplugging. | Internal backup battery is low or faulty. | Keep the unit plugged in for several hours to allow the internal battery to charge. If the issue persists, contact customer support. |
| Overload alert triggered. | Connected appliance exceeds the monitor's maximum wattage (1800W). | Unplug the appliance immediately. Do not connect appliances that exceed the specified maximum power rating. |
