3. Setup
3.1 Battery Installation
The ANENG B15 requires two 1.5V AAA batteries (not included). To install the batteries:
- Remove the back battery compartment cover.
- Insert two AAA batteries, ensuring correct polarity.
- Replace the battery compartment cover securely.

3.2 Self-Test Function
Before use, perform a self-test to ensure the battery is sufficient:
- Hold the pen in one hand.
- Touch the side touch pole with your other hand.
- A green light indicates sufficient battery. If the light is not on, the battery needs to be replaced.

4. Operating Instructions
The ANENG B15 offers a wide range of electrical testing functions. Always ensure safety precautions are followed when working with electricity.
4.1 Zero/FireWire Recognition
To distinguish between zero and live wires:
- Touch the touch pole on the side of the electric pen with your hand.
- Insert the electric pen's tip into the socket or touch the wire.
- Zero Line: The green light will be continuously on.
- Live Wire (FireWire): The red light will flash, and the pen will beep.

4.2 Electrical On-Off Detection
To check if a wire's inner core is intact or disconnected:
- Place your hand on the touch pole, completing the human body circuit.
- Contact the inner core of the plug wire with the tester pen's tip.
- If the green light is on, the inner core is intact.
- If the light does not illuminate, the wire core is disconnected or damaged.

4.3 DC Detection
To test DC power sources like batteries:
- Press and hold the positive electrode of the battery.
- Touch the negative electrode with the tester pen's tip.
- A green light indicates sufficient power.
- If the light is not on, the battery has no power or insufficient power.

4.4 Line Breakpoint Lookup
To locate breakpoints in a wire:
- Move the tester pen along the wire.
- A bright blue light indicates the line is continuous and unobstructed.
- If the blue light turns off, it indicates a line disconnection at that point.

4.5 AC Voltage Sensing (NCV)
The built-in Non-Contact Voltage (NCV) sensor detects AC voltage without direct contact, enhancing safety:
- Bring the tip of the tester pen near an AC voltage source (e.g., outlet, wire).
- The LED blue induction indicator will light up when AC voltage is detected.

4.6 Flashlight Function
For working in dark environments:
- Press the orange flashlight button to turn on the LED flashlight.
- Press it again to turn it off.

4.7 Screwdriver Function
The tip of the tester pen doubles as a one-word (flathead) screwdriver:
- Use the high-hardness chromium vanadium steel batch tip for light-duty screwing tasks.

5. Maintenance
- Cleaning: Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the tester pen in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery: If the device will not be used for an extended period, remove the batteries to prevent leakage and damage.
- Material: The body is made of ABS, and the probe is chromium vanadium steel, ensuring durability and wear resistance.
6. Troubleshooting
- Device does not turn on: Check if batteries are installed correctly and have sufficient power. Replace batteries if necessary.
- Inconsistent readings: Ensure proper contact with the test point and that your hand is touching the touch metal for functions requiring a human body circuit. Check battery level.
- Line breakpoint lookup not working: Ensure the pen is moved slowly and consistently along the wire. Verify the wire is indeed disconnected.

8. User Tips
- Always ensure your hands are dry and you are wearing appropriate safety gear when performing electrical tests.
- For non-contact voltage detection, hold the pen close to the wire or outlet. The closer you are, the more accurate the detection.
- When testing for line breakpoints, move the pen slowly along the wire to pinpoint the exact location of the break.
- The built-in flashlight is very useful in dimly lit areas, making it easier to see the test points.
