4. Configuração
4.1 Instalação da bateria
The INKBIRDPLUS INK-IFT03 requires one 9V battery (included). To install or replace the battery:
- Localize a tampa do compartimento da bateria na alça do termômetro.
- Abra a tampa do compartimento da bateria.
- Insira uma nova bateria de 9V, certificando-se da polaridade correta (+/-).
- Feche bem a tampa do compartimento da bateria.
O dispositivo agora está pronto para uso.
5. Instruções de operação
5.1 Medição básica de temperatura
- Aponte o termômetro para o objeto alvo.
- Pressione e segure o Gatilho de medição. 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 Relação Distância/Ponto (D:P)
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 Unidades de temperatura de comutação (°C/°F)
Para alternar entre Celsius (°C) e Fahrenheit (°F):
- Com o dispositivo ligado, pressione e segure o Botão de luz de fundo/laser for approximately 2-3 seconds.
- The unit displayed on the LCD will change.

5.4 Emissividade ajustável
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.
Para ajustar a emissividade:
- Pressione o Botão de mudança de modo repeatedly until "EMS" appears on the bottom of the LCD display.
- Use o Chave alta or Tecla para baixo to adjust the emissivity value (e.g., 0.95 for most organic materials, 0.98 for ice, 0.94 for oil).
- Pressione o Gatilho de medição para salvar a configuração e retornar ao modo de medição.

Image 5.3: Adjusting emissivity for different materials like oil and ice.
Refer to the table below for common emissivity values:
| Material | Emissividade | Material | Emissividade |
|---|---|---|---|
| Alumínio (oxidado) | 0.20-0.40 | Papel | 0.90 |
| Brass (oxidized) | 0.61 | Areia | 0.90 |
| Iron (oxidized) | 0.78 | Argila | 0.92-0.96 |
| Asfalto | 0.95 | Água | 0.93 |
| Concreto | 0.95 | Gelo | 0.98 |
| Madeira | 0.90 | Plástico | 0.95 |
| Borracha | 0.95 | Óleo | 0.94 |
