2. Setup
Follow these steps to prepare your FLIR T540-EST for operation:
- Unboxing: Carefully remove all components from the packaging. Verify that all items listed in the packing slip are present.
- Battery Installation: The camera requires two Lithium Ion batteries (included). Insert the batteries into the designated compartment, ensuring correct polarity. Charge batteries fully before first use using the provided charger.
- Lens Attachment: The 24-degree lens is typically pre-attached. If interchanging lenses, align the lens with the camera body's mount and rotate until it clicks securely into place.
- Mounting: For stable and consistent screening, mount the camera on a tripod or a stable surface. Ensure the camera is positioned at an appropriate height for the subjects being screened.
- Initial Power-On: Press and hold the power button until the FLIR logo appears on the screen.
3. Operating Instructions
The FLIR T540-EST is designed for intuitive operation. Familiarize yourself with its key features:
- Power On/Off: Press and hold the power button to turn the camera on or off. A short press will put the camera into standby mode.
- Screen-EST Mode: Activate the dedicated Screen-EST mode for streamlined temperature screening. This mode provides visual positioning guides, automatically samples to maintain an updated temperature average, and displays graphic pass/fail indicators.
- Temperature Measurement: The camera measures temperatures from 15°C to 45°C (59°F to 113°F). Ensure subjects are within the optimal screening distance for accurate readings.
- Laser-Assisted Autofocus: Utilize the laser-assisted autofocus feature to ensure sharp focus on the subject's face, which is critical for precise temperature readings.
- Ergonomic Design: The 180° rotating optical block allows for comfortable viewing angles during extended screening sessions. The vivid 4-inch capacitive touchscreen provides an interactive interface for settings and viewing.
- Interpreting Results: In Screen-EST mode, the camera will provide clear visual cues (e.g., green for pass, red for fail) based on configured temperature thresholds.

4. Maintenance
Proper maintenance ensures the longevity and accuracy of your FLIR T540-EST:
- Cleaning the Lens: Use a soft, lint-free cloth specifically designed for optical lenses. Gently wipe the lens surface to remove dust or smudges. Avoid abrasive materials or harsh chemicals.
- Cleaning the Screen and Body: Use a soft, damp cloth with a mild cleaning solution (if necessary) to clean the touchscreen and camera body. Do not spray liquids directly onto the camera.
- Battery Care: Always use the FLIR-approved charger. Do not expose batteries to extreme temperatures. If storing the camera for an extended period, ensure batteries are partially charged (around 50%) and remove them from the device.
- Storage: Store the camera in its protective case in a cool, dry environment, away from direct sunlight and extreme temperatures.
5. Troubleshooting
