4. Configuración
4.1 Instalación da batería
- Localiza o compartimento das pilas na asa do termómetro.
- Abra a tapa do compartimento da batería.
- Introduza unha pila de 9 V, asegurándose de manter a polaridade correcta (+/-).
- Pecha a tapa do compartimento da batería de forma segura.
4.2 Encendido inicial
After installing the battery, the device is ready for use. Press the trigger to power on the device and begin measurement.
5. Instrucións de funcionamento
5.1 Tomar unha medida
- Point the thermometer at the target surface. Ensure the target is within the field of view indicated by the dual laser pointers.
- Press and hold the trigger. The temperature reading will appear on the LCD display.
- Release the trigger to hold the reading on the display (Data Hold function).
5.2 Comprensión da relación distancia-punto (D:S)
The BT-1880 has a 50:1 D:S ratio. This means that at a distance of 50 units from the target, the measurement spot diameter will be 1 unit. For example, at 50 inches away, the measurement spot will be 1 inch in diameter. To ensure accurate readings, the target area should be larger than the spot size.
5.3 Axuste da emisividade
Emissivity (ε) is a measure of an object's ability to emit infrared energy. Different materials have different emissivity values. The BT-1880 allows adjustment from 0.1 to 1.0. For accurate measurements, adjust the emissivity setting to match the material being measured. Common emissivity values are often found in reference tables.

5.4 Unidades de temperatura de conmutación (°C/°F)
Press the "°F/°C" button to toggle between Celsius and Fahrenheit temperature units.
5.5 Using Measurement Modes (MAX/MIN/AVG)
Press the "MODE" button to cycle through different measurement modes:
- MÁX .: Mostra a temperatura máxima rexistrada durante unha medición continua.
- MIN: Mostra a temperatura mínima rexistrada durante unha medición continua.
- AVG: Mostra a temperatura media rexistrada durante unha medición continua.

5.6 Uso da lanterna LED
Press the "BL" button to turn the integrated LED flashlight on or off, assisting in low-light conditions.
6. Mantemento
6.1 Limpeza do dispositivo
To clean the thermometer, wipe the casing con anuncioamp cloth. Do not use abrasive cleaners or solvents. Ensure the lens is clean and free of dust or debris for accurate readings.
6.2 Substitución da batería
When the low battery indicator appears on the display, replace the 9V battery as described in Section 4.1.
6.3 Almacenamento
Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.
7 Solución de problemas
- Lecturas inexactas:
- Asegúrate de que o axuste de emisividade coincida co material que se está a medir.
- Verify the distance to the target and ensure the target size is appropriate for the 50:1 D:S ratio.
- Check for obstructions or dirt on the lens.
- Allow the device to acclimate to the ambient temperature if moved from a significantly different temperature environment.
- Sen problemas de pantalla/alimentación:
- Comprobe se a batería está instalada correctamente e ten a carga suficiente. Substitúaa se é necesario.
- O láser non funciona:
- Ensure the device is powered on. If the laser is still not visible, contact customer support.
Remember: This thermometer is not designed for measuring human or animal body temperature. Readings on living beings will be inaccurate and should not be used for medical purposes.
