6.4 Justering af emissivitet
Emissivity (ε) is a crucial factor for accurate infrared temperature measurement. Different materials emit infrared energy differently. The BT-1600-APP allows you to adjust the emissivity from 0.1 to 1.0 to match the surface being measured.
- Press the "E/E" button to enter emissivity adjustment mode.
- Use the "UP" and "T/DN" buttons to increase or decrease the emissivity value.
- Refer to common emissivity tables for various materials (e.g., oil: 0.94, asphalt: 0.9, water: 0.96).

Figure 10: Emissivity adjustment for different materials.
6.5 Forholdet mellem afstand og punkt (D:S)
The D:S ratio of 30:1 indicates that at a distance of 30 units, the measurement spot size is 1 unit. For example, at 30 inches away, the measurement spot is 1 inch in diameter. This allows for safer measurement by keeping you away from heat sources while maintaining accuracy.

7. Vedligeholdelse
- Rensning: Brug en blød, damp cloth to clean the device's exterior. Do not use abrasive cleaners or solvents. Ensure the lens is clean and free of dust or debris for accurate readings.
- Opbevaring: Store the thermometer in its portable carrying case when not in use to protect it from dust, moisture, and physical damage. Store in a cool, dry place within the specified storage temperature range (-20~60℃).
- Batteripleje: Recharge the battery regularly, even if not frequently used, to maintain its lifespan. Avoid fully discharging the battery for extended periods.
8. Fejlfinding
- Upræcise læsninger:
- Kontrollér og juster emissivitetsindstillingen, så den passer til det materiale, der måles.
- Sørg for, at linsen er ren.
- Verify the distance to spot ratio is appropriate for your measurement.
- Make sure the ambient temperature is within the specified range for accuracy (23℃~28℃).
- Enheden tænder ikke:
- Kontroller, om batteriet er korrekt installeret og opladet.
- Connect the device to a charger to see if it powers on.
- Problemer med appforbindelse:
- Sørg for, at Bluetooth er aktiveret på din mobilenhed.
- Keep the thermometer and phone close during pairing.
- Restart both the thermometer and the app.
- Tjek, om appen er opdateret til den nyeste version.
- Automatic Shutdown Too Soon:
- The device has an automatic shutdown function after about 10 seconds of inactivity. This can be adjusted in the app settings.
9. Brugertips
- For best accuracy, always ensure the target surface is clean and free of obstructions.
- When measuring shiny surfaces, consider applying a matte black paint or tape to the area to improve emissivity and accuracy.
- Utilize the data logging feature in the app for long-term monitoring and analysis of temperature trends.
- The dual laser pointers are excellent for pinpointing the exact measurement area, especially from a distance.
- Remember to adjust emissivity for different materials to get the most accurate readings.
10. Sikkerhedsoplysninger
