2.2 První zapnutí
After battery installation, the device is ready for use. Point the thermometer at a surface and press the trigger to activate the display and take a reading.
3. Návod k obsluze
3.1 Měření teploty
- Hold the thermometer by its handle.
- Point the infrared sensor (located at the front) towards the target surface.
- Stiskněte a podržte spoušť. Aktivuje se laserové ukazovátko, které pomůže zaměřit se na požadované místo měření.
- 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.
