2. Safety Precautions
To ensure safe operation and prevent damage to the device or personal injury, please observe the following precautions:
- Voltage and Current Limits: Do not exceed the maximum voltage of 60V or the maximum current of 200A. Exceeding these limits will damage the wattmeter and may cause personal injury.
- Protective Equipment: Always use appropriate safety equipment when working with electrical systems.
- Proper Control: Ensure that current and voltage are properly controlled for your specific application.
- Inline Use Only: The wattmeter is designed as an inline meter for measurement purposes. Do not use it as a power supply.
- Secure Connections: Loose connections can lead to component damage and inaccurate readings. Ensure all connections are secure.

3. Product Features
- High Precision Measurement: Measures current from 0-200A (0.01A resolution) and voltage from 0-60V (0.01V resolution).
- Comprehensive Data: Calculates and displays voltage, current, power, charge (Amp-hour), and energy (Watt-hour).
- Peak and Minimum Value Capture: Records peak current (Ap), maximum power (Wp), and minimum voltage (Vm) during operation.
- LCD Backlight Display: Features a 16×2 LCD screen with backlight for clear visibility in various lighting conditions, including direct sunlight.
- Wide Operating Voltage: Operates from 4.8V to 60V. Can function at 0V with an optional auxiliary battery.
- Overcurrent Protection: Helps prevent peak currents from damaging batteries, motor controllers, motors, wiring, and connectors.
- Efficient Design: Incorporates a ventilation hole design for heat dissipation and uses high-quality tin-copper core for high load capacity and low resistance.

4. Setup and Connections
The wattmeter is designed for inline measurement. Connect it between your power source (e.g., battery, solar panel) and your load (e.g., motor, RC aircraft). Ensure correct polarity and secure connections.
- Source Connection: Connect the “SOURCE” side of the wattmeter to your power source. The red wire is positive (+), and the black wire is negative (-).
- Load Connection: Connect the “LOAD” side of the wattmeter to your device or system that consumes power. The red wire is positive (+), and the black wire is negative (-).
- Auxiliary Battery (Optional): For measurements at 0V or for powering the display when the main circuit voltage is too low, an optional auxiliary battery (6.0V-60V) can be connected to the dedicated port.

5. Operating Instructions
Once connected, the wattmeter will automatically power on and display real-time measurements on its LCD screen. The display shows various parameters simultaneously.
5.1. Display Readings
The LCD screen provides the following information:
- Current (A): Instantaneous current flow in Amperes.
- Voltage (V): Instantaneous voltage in Volts.
- Power (W): Instantaneous power consumption in Watts.
- Charge (Ah): Accumulated charge in Amp-hours. This value accumulates until reset or power off.
- Energy (Wh): Accumulated energy in Watt-hours. This value accumulates until reset or power off.
- Peak Current (Ap): The highest current recorded during the measurement period.
- Maximum Power (Wp): The highest power recorded during the measurement period.
- Minimum Voltage (Vm): The lowest voltage recorded during the measurement period.
5.2. Resetting Accumulated Values
The accumulated Charge (Ah) and Energy (Wh) values will reset when the device is powered off or manually reset. Refer to the included English manual for specific instructions on manual reset procedures, if available.
