3.1 Taking a Temperature Measurement
- Hold the thermometer by its handle.
- Point the infrared sensor (located at the front) towards the target surface.
- Press and hold the trigger. The laser pointer will activate to help aim at the desired measurement spot.
- The temperature reading will appear on the digital display. Release the trigger to hold the last reading on the screen.
For accurate readings, ensure the target area is larger than the thermometer's spot size at the measurement distance. The device has a distance-to-spot ratio of 12:1, meaning at 12 inches, it measures a 1-inch spot.

3.2 Aṣayan Ẹka (Fahrenheit/Celsius)
The thermometer allows switching between Fahrenheit (°F) and Celsius (°C) temperature units. Refer to the device's buttons, typically located near the display, to toggle between these units. A dedicated button or a combination of buttons may be used.
3.3 Backlight Feature
The digital display includes a backlight for improved visibility in low-light conditions. This feature usually activates automatically when the device is in use or can be toggled with a specific button.
