4. Configuració
4.1 Instal·lació de la bateria
The INKBIRDPLUS INK-IFT03 requires one 9V battery (included). To install or replace the battery:
- Localitzeu la tapa del compartiment de les piles al mànec del termòmetre.
- Obriu la tapa del compartiment de la bateria.
- Insert a new 9V battery, ensuring the correct polarity (+/-).
- Tanqueu bé la tapa del compartiment de la bateria.
El dispositiu ja està llest per al seu ús.
5. Instruccions de funcionament
5.1 Mesura bàsica de la temperatura
- Apunta el termòmetre cap a l'objecte objectiu.
- Manteniu premut el botó Trigger de mesurament. The laser pointer will activate, indicating the measurement area.
- The temperature reading will appear on the LCD display. For more accurate readings, hold the trigger for 2-3 seconds.
- Release the trigger to hold the reading on the display. The device will automatically shut off after 30 seconds of inactivity to conserve battery.
5.2 Relació distància-punt (D:S)
The INK-IFT03 has a Distance to Spot Ratio (D:S) of 16:1. This means that at a distance of 16 units from the target, the measurement spot size will be 1 unit. For example, if you are 16 inches away from an object, the thermometer will measure a 1-inch diameter spot. To ensure accurate readings, make sure the target area is larger than the spot size, especially when measuring from a distance.

5.3 Canvi d'unitats de temperatura (°C/°F)
Per canviar entre Celsius (°C) i Fahrenheit (°F):
- Amb el dispositiu encès, premeu i manteniu premut el botó Botó de llum de fons/làser durant aproximadament 2-3 segons.
- The unit displayed on the LCD will change.

5.4 Emissivitat ajustable
Emissivity (E) is a measure of an object's ability to emit infrared energy. Different materials have different emissivity values. For accurate temperature readings, it is important to adjust the thermometer's emissivity setting to match the target material. The INK-IFT03 has an adjustable emissivity range of 0.1 to 1.0.
Per ajustar l'emissivitat:
- Premeu el botó Botó de canvi de mode repeatedly until "EMS" appears on the bottom of the LCD display.
- Utilitza el Tecla amunt or Tecla avall to adjust the emissivity value (e.g., 0.95 for most organic materials, 0.98 for ice, 0.94 for oil).
- Premeu el botó Trigger de mesurament per guardar la configuració i tornar al mode de mesura.

Image 5.3: Adjusting emissivity for different materials like oil and ice.
Refer to the table below for common emissivity values:
| Material | Emissivitat | Material | Emissivitat |
|---|---|---|---|
| Alumini (oxidat) | 0.20-0.40 | Paper | 0.90 |
| Brass (oxidized) | 0.61 | Sorra | 0.90 |
| Iron (oxidized) | 0.78 | Argila | 0.92-0.96 |
