Towallmark Watt Meter, Electricity Usage Monitor

Introduction

This instruction manual provides comprehensive guidance for the safe and effective use of your Towallmark Watt Meter (Model HR-0120). This device is designed to monitor the electricity consumption of connected appliances, displaying various parameters such as wattage, voltage, current, frequency, power factor, and cumulative energy usage (kWh) along with associated costs. Please read this manual thoroughly before operation and retain it for future reference.

Product Features

• Large Backlit LCD Display: Features a clear, wide-angle LCD with backlight for easy readability, even in low-light conditions.
• High Accuracy Measurement: Equipped with a high-precision current sensor to accurately display real-time voltage, current, electric power, timekeeping, and billing. Measurements for voltage and power are within 2% accuracy.
• Overload Protection: Provides an audible warning and displays "OVERLOAD" on the LCD if the connected appliance's power exceeds 1800W, automatically disconnecting power to prevent damage.
• User-Friendly Interface: Utilizes kWh as the unit for power consumption calculation and features four independent keys for quick access to different power parameters.
• Effective Energy Monitoring: Helps identify high-energy-consuming appliances, enabling users to reduce power consumption and save on electricity costs by measuring various parameters and cumulative kilowatt-hours.

Safety Information

• Do not exceed the maximum load of 15A or 1800W. Overloading can cause damage to the device and connected appliances, and poses a fire hazard.
• Ensure the device is used in a dry environment. Avoid exposure to water or high humidity.
• Do not disassemble or attempt to repair the device. Refer all servicing to qualified personnel.
• Keep out of reach of children.
• Always ensure the appliance is properly plugged into the watt meter and the watt meter is securely plugged into a wall outlet.

Understanding Display Modes

1. Mode 1: Time/Watt/Cost Display
   Shows the elapsed time of monitoring, current power consumption in Watts (W), and the accumulated cost based on your set electricity price.
2. Mode 2: Time/Cumulative Electrical Quantity Display
   Displays the elapsed time and the total cumulative energy consumed in kilowatt-hours (kWh).
3. Mode 3: Time/Voltage/Frequency Display
   Shows the elapsed time, the current line voltage (V), and the frequency (Hz) of the AC power.
4. Mode 4: Time/Current/Power Factor Display
   Indicates the elapsed time, the current flowing through the appliance in Amperes (A), and the power factor (PF).
5. Mode 5: Time/Minimum Power Display
   Displays the elapsed time and the lowest recorded power consumption (W) since monitoring began.
6. Mode 6: Time/Maximal Power Display
   Shows the elapsed time and the highest recorded power consumption (W) since monitoring began.
7. Mode 7: Time/Price Display
   Displays the elapsed time and the set electricity price per kWh.

Data Hold Function

The watt meter is equipped with a data hold function. When the appliance is removed from the meter or the meter is unplugged from the wall socket, the last recorded data will be saved. This allows you to review the final readings even after disconnecting the power.

Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the watt meter in a cool, dry place when not in use.
• Inspection: Periodically check the device and its plugs for any signs of damage or wear. Discontinue use if damage is observed.

Troubleshooting

• Display is blank: Ensure the watt meter is securely plugged into a live wall outlet. Check if the outlet is functioning correctly by plugging in another device.
• "OVERLOAD" warning displayed: This indicates that the connected appliance is drawing more than 1800W. Immediately unplug the appliance. Do not use the watt meter with appliances exceeding its maximum rated power.
• Incorrect readings: Verify that the electricity price per kWh is set correctly. Ensure the appliance is fully functional and not drawing intermittent power.
• Buttons unresponsive: Try unplugging the watt meter from the wall outlet for a few seconds, then plug it back in to reset.
