1. Introduction
The ANENG B15 Induction Tester Pen is a professional electrical testing tool designed for safe and accurate detection of AC voltage, zero/live wire identification, line breakpoint lookup, electrical on-off detection, and DC detection. It features a highlight color light display and a built-in flashlight for convenience in various working environments.

2. Product Overview
The ANENG B15 is a versatile tool for electricians and DIY enthusiasts. It combines multiple functions in a compact, pen-shaped design.

- Induction indicator light: Bright blue light.
- High pressure indicator: Bright red light.
- Flashlight button: Activates the LED flashlight.
- Touch metal: The touch pole that needs to be contacted during measurement.
- Low voltage/on-off indicator light: Bright green light.
- LED flashlight: Assists with night work.
- Chromium vanadium steel batch: High hardness one-word screwdriver tip.
3. Setup
3.1 Battery Installation
The ANENG B15 requires two 1.5V AAA batteries (not included). Follow these steps to install them:
- 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 device is functioning correctly and has sufficient battery power:
- Hold the pen in one hand.
- Touch the touch metal (probe) with your other hand.
- A green light indicates that the battery is sufficient. If the light is not on, the battery needs to be replaced.

4. Operating Instructions
4.1 Zero FireWire Recognition (Live/Neutral Wire Detection)
To distinguish between live and neutral wires:
- Touch the touch pole on the side of the electric pen with your hand.
- Insert the electric pen's probe into the socket or touch the wire.
- Zero Line: The green light is always on when the detection head touches the zero wire.
- FireWire (Live Line): The red light flashes and the pen beeps when the detection head touches the live wire.

4.2 Electrical On-Off Detection
To check the continuity of a wire or device:
- Place your hand at the touch level of the pen, completing the human body circuit.
- Touch the inner core of the plug wire or the wire to be tested with the probe.
- If the inner core of the plug wire is intact, the green light will be on.
- If the light is not on, it indicates that the wire core is disconnected or damaged somewhere.

4.3 DC Detection
To detect DC power in batteries or other DC sources:
- As shown in the video, press and hold the positive electrode of the battery.
- Touch the touch electrode of the electric pen to the negative electrode of the battery.
- The green light will be on to indicate that the power is sufficient.
- If the light is not on, it means there is no power or insufficient power.

4.4 Line Breakpoint Lookup
To locate breakpoints in a wire:
- Move the electric pen along the wire.
- Where the LED blue light is on, the line is smooth and continuous.
- If the blue light is not on, it indicates a disconnection in the line.

4.5 AC Voltage Sensing (Non-Contact)
For non-contact AC voltage detection:
- The built-in sensor detects AC voltage without direct contact.
- When AC voltage is detected, the LED blue induction indicator will light up. This helps prevent electric shock.

4.6 Flashlight Function
The tester pen includes an LED flashlight for working in low-light conditions:
- Press the orange flashlight button (labeled '3' in Figure 2) to turn on the flashlight.
- This assists in illuminating the measurement position during night work or in dark environments.

5. Maintenance
- Keep the tester pen clean and dry. Wipe with a soft, dry cloth.
- Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Replace batteries promptly when the self-test indicates low power to ensure accurate readings.
- The screwdriver tip is made of chromium vanadium steel, offering high hardness and wear resistance. Avoid using it for tasks beyond its intended purpose to maintain its integrity.

6. Troubleshooting
- No light during self-test: Check and replace the AAA batteries.
- No green light during electrical on-off detection: The wire core may be damaged or disconnected.
- No light during DC detection: The battery being tested may be dead or have insufficient power.
- No blue light during line breakpoint lookup: Indicates a disconnection in the line at that point.
- Inaccurate readings: Ensure the batteries are fresh and the probe is making proper contact (where applicable).
