7.1 Gbanyụọ ma ọ bụ gbanyụọ
Press the red Power button to turn the device on. Press it again to turn it off. The device will emit a beep and the display will light up upon powering on.
7.2 AC anaghị akpọtụrụ Voltage Nchọpụta
- Gbanwuo ngwaọrụ.
- Place the probe tip near the wire, outlet, or electrical component you wish to test.
Nchọpụta Waya Dị Ndụ: If a live AC voltage is detected, the device will emit rapid beeps, the red alarm light will flash, and the signal strength indicator (analog bar) will show a high level (e.g., red segments). The display will show "Live wire".

Figure 7.1: Illustration of live wire detection, showing red light and full signal strength. 
Figure 7.2: Demonstrates detection of live wire (red light) and neutral wire (no light/green light). Neutral Wire Detection: If a neutral wire or no voltage is detected, the device will typically show a green light on the signal strength indicator and emit slower beeps or no alarm, indicating a "Null" state.
- The analog bar on the display screen will become higher or lower with the intensity of the sensed voltage signal. The beeping sound will also become faster or slower with the signal strength.

7.3 Ndozi mmetụta uche
The device features adjustable sensitivity for different detection scenarios:
- Short press the blue Sensitivity / Flashlight Lighting button to switch between high (Hi) and low (Lo) sensitivity modes.
- Low Sensitivity (Lo): Default mode, typically for detecting 48V~1000V AC. Suitable for general detection.
- High Sensitivity (Hi): For detecting lower voltages, typically 12V~1000V AC. Useful for detecting voltage in thinner wires or at a greater distance.

7.4 Flashlight Operation
Long press the blue Sensitivity / Flashlight Lighting button to turn the flashlight on or off. This is useful for working in dimly lit areas.

7.5 Breakpoint Detection
The device can assist in identifying breakpoints in a live wire. Move the probe along the wire; the alarm and light will cease at the point where the circuit is interrupted.


7.6 Mmechi akpaaka
To conserve battery life, the device will automatically shut down after approximately 3 minutes if no induction signal is detected or no operation is performed.

- Inconsistent readings: Ensure the probe is close enough to the conductor. Check for strong electromagnetic interference in the area.
- No detection on a live circuit: Verify the device is powered on and in the correct sensitivity mode (try "Hi" mode). Ensure the probe tip is clean.
- Echiche ụgha: This can occur due to static electricity or strong electromagnetic fields. Try moving to a different location or reducing sensitivity.
10. Ndụmọdụ onye ọrụ
- Always test the detector on a known live circuit (e.g., a working outlet) before using it on an unknown circuit to confirm it's functioning correctly.
- Use the flashlight feature in dark environments to improve visibility and safety.
- Experiment with both "Hi" and "Lo" sensitivity settings to find the most appropriate mode for your specific task.
- The compact design with a pen clip makes it easy to carry in a pocket for quick access.
