3. Setup

Initial Charging

Before first use, fully charge the HT-A1 camera. Connect the provided data cable to the Micro USB port on the device and the other end to a USB power adapter (included) or a computer's USB port. The charging indicator will show the charging status.

Powering On/Off

• To Power On: Press and hold the 'On/Off' button (usually marked with a power symbol) until the screen illuminates.
• To Power Off: Press and hold the 'On/Off' button until the device shuts down. The device also features an auto-off function, which can be set to 5 minutes, 20 minutes, or disabled.

4. Operation

Navigating the Menu

The HT-A1 features a user-friendly interface controlled by the navigation and selection buttons:

• Menu Button: Press to access the main menu.
• Navigation Buttons (Up/Down/Left/Right): Use these arrows to move through menu options and adjust settings.
• Select/Enter Button: Press to confirm a selection or enter a submenu.
• Save Button: Used to save captured images.

Understanding the Display

The 3.2-inch TFT screen displays real-time thermal images along with critical data. The main screen typically shows the thermal image, central point temperature, maximum and minimum temperatures within the view, emissivity setting, and battery status.

Adjusting Settings

Emissivity

Emissivity (ε) is a measure of an object's ability to emit infrared energy. Different materials have different emissivity values. For accurate temperature measurements, adjust the emissivity setting (0.01 to 1.00) to match the material being inspected. Consult a standard emissivity table for common materials.

Color Palettes

The HT-A1 offers five color palettes to visualize thermal data. Each palette highlights temperature differences in a unique way, making it easier to identify anomalies depending on the application.

• Rainbow: Provides a full spectrum of colors, often used for general thermal analysis.
• Iron Oxide Red: Highlights hot spots with red and yellow tones.
• Cold Color: Emphasizes cooler areas with blue and purple tones.
• Black & White: Simple grayscale representation, useful for high contrast.
• White & Black: Inverted grayscale, also for high contrast.

Capturing and Saving Images

To capture a thermal image, aim the camera at the target object and press the 'Save' button. The image will be stored in the internal 3GB memory in JPG format.

Transferring Data

Images stored on the HT-A1 can be easily transferred to a computer using the provided USB data cable. Connect the camera to your computer, and it will appear as a removable storage device, allowing you to copy the JPG files.
