4.3 Articulating Probe Control

Figure 4: The probe tip can be articulated up to 210 degrees in two directions using the control wheel.
The AT040 features a 210° two-way articulating probe. To control the probe tip:
- Locate the control wheel on the handle of the borescope.
- Rotate the wheel to bend the probe tip in the desired direction.
- The probe tip can be locked at any angle by holding the wheel in position, allowing for stable viewing.
4.4 Dual-Lens and Split-Screen Functionality

The borescope is equipped with both a front-facing and a side-facing lens. To utilize this feature:
- Press the dedicated dual-lens button (refer to device interface for icon, typically two overlapping squares or similar) to switch between single front view, single side view, or split-screen display.
- In split-screen mode, both camera feeds are shown simultaneously on the 7-inch IPS screen, enhancing inspection efficiency.
4.5 Adjusting LED Brightness

Figure 6: The IP67 rated probe features adjustable LED lights for optimal illumination in various conditions.
To adjust the brightness of the LED lights on the probe tip:
- Locate the LED brightness control button (often indicated by a light bulb icon).
- Press the button repeatedly to cycle through different brightness levels or use a dedicated dial if available.
4.6 Capturing Photos and Videos
The borescope supports capturing JPG images and AVI video recordings.
- To take a photo: Press the 'Photo' button (typically a camera icon). The image will be saved to the inserted memory card.
- To record a video: Press the 'Video' button (typically a video camera icon) to start recording. Press it again to stop recording. Videos are saved to the memory card.
- The device also supports audio recording via a built-in microphone during video capture.
4.7 Flexible Rigid Gooseneck

Figure 7: The flexible rigid gooseneck probe can be bent and shaped to suit various inspection needs.
The probe cable is designed to be flexible yet rigid enough to hold its shape. This allows you to bend, shape, and extend the probe to navigate complex pathways and maintain the desired viewing angle during inspection.
