1. Introduction
This manual provides instructions for the proper installation, operation, and maintenance of the Macro Lens designed for the TOOLTOP ET15S Thermal Imaging Multimeter. This accessory enhances the thermal camera's capability to capture detailed thermal images of small components and intricate circuits, which is crucial for precise diagnostics and analysis.
2. Important Notes
- Compatibility: This macro lens is exclusively designed for the TOOLTOP ET15S thermal imaging multimeter. It is not compatible with ET14S, ET13S, or any other models. Attempting to use it with incompatible devices may result in improper fit or damage.
- Working Distance: The optimal working distance for this macro lens is approximately 5 cm (2 inches). If the distance between the lens and the target object exceeds this range, the thermal image may become blurred. For objects beyond 5 cm, use the thermal camera's normal imaging mode without the macro lens.

4. Setup and Installation
Follow these steps to correctly install the macro lens onto your TOOLTOP ET15S thermal camera:
- Prepare the Lens: Hold the macro lens and tilt it slightly for easier insertion.
- Insert Front Corners: Carefully insert the front two corners of the macro lens into the designated card slot on the thermal camera.
- Secure the Lens: Gently press the back of the macro lens until the entire lens assembly is securely seated within the card slot. Ensure it clicks into place or feels firmly attached.

For a visual guide, please refer to the installation video below:

5. Operation
Once installed, the macro lens allows for detailed thermal inspection of small objects. To achieve optimal results:
- Positioning: Ensure the object you are inspecting is approximately 5 cm (2 inches) from the macro lens.
- Fine Adjustment: During use, you may need to slightly move the macro lens (and thus the thermal camera) left and right to find the clearest focus and best thermal detail.
- Observe Results: The thermal camera display will show a significantly clearer and more detailed thermal image of small components when the macro lens is correctly positioned, as demonstrated in Figure 2.
6. Maintenance
To ensure the longevity and performance of your macro lens:
- Cleaning: Use a soft, lint-free cloth specifically designed for optical lenses to gently wipe the lens surface. Avoid abrasive materials or harsh chemicals.
- Storage: When not in use, store the macro lens in a clean, dry place, preferably in its original packaging or a protective case, to prevent dust and scratches.
- Handling: Avoid touching the lens surface directly with your fingers to prevent smudges and oils.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermal image is blurry with macro lens installed. | Object is outside the optimal working distance. | Ensure the object is approximately 5 cm from the macro lens. Adjust the distance until the image is clear. |
| Macro lens does not fit the thermal camera. | Incompatible thermal camera model. | Verify that your thermal camera is a TOOLTOP ET15S. This macro lens is not compatible with other models. |
| Lens appears dirty or smudged. | Dust, fingerprints, or debris on the lens surface. | Clean the lens gently with a soft, lint-free optical cleaning cloth. |

9. User Tips
- Precision Adjustment: When examining very small components, slight movements of the thermal camera (and thus the macro lens) can significantly improve focus and clarity. Don't hesitate to adjust your position minutely.
- Lighting Conditions: While thermal imaging doesn't rely on visible light, good ambient lighting can help you physically position the camera and lens more accurately relative to your target.
- Stable Platform: For the best results, especially when working at the precise 5 cm distance, consider using a stable platform or tripod for your thermal camera to minimize hand shake.
