5. Setup

5.1 Charging the Battery

The MT13S is equipped with a built-in lithium battery. Before first use, ensure the device is fully charged using the provided Type-C USB cable. Connect the cable to the Type-C USB port on the device and to a suitable USB power source.

5.2 Powering On/Off

Press and hold the Power Button (refer to Figure 2) for a few seconds to turn the device on or off.

6. Operating Instructions

6.1 Switching Between Modes

Press the IR Camera / Multimeter Switch Button (refer to Figure 2) to toggle between the thermal imaging mode and the multimeter mode.

6.2 Thermal Imaging Mode

In thermal imaging mode, the device displays a thermal image with a resolution of 192x192 pixels. The measurement temperature range is -20℃ to +550℃.

• Understanding the Display: Refer to Figure 3 for a detailed explanation of the IR camera display elements, including hot/cold spot indicators, center point temperature, and battery status.
• Color Palettes: The MT13S offers five distinct color palettes to visualize temperature differences. To change the palette, navigate through the system settings or use the touch screen interface. The available palettes are: Iron Red, Rainbow, Fusion, White Heat, and White Heat Highlights.
