4. Betjening

Once powered on, the device will automatically begin displaying real-time decibel levels, temperature, humidity, and time. No further action is required for continuous monitoring.

5. Forståelse af aflæsninger

The device provides clear readings for decibel levels, temperature, and humidity. Refer to the table below for general comfort guidelines based on these measurements.

Figure 3: Decibel, Temperature, and Humidity Comfort Level Guidelines.

Decibel (dB) Readings:

• The device measures sound levels from 30 dB to 130 dB.
• Lower dB values indicate quieter environments, while higher values indicate louder environments.
• The decibel level indicator (bar graph) provides a quick visual reference of sound intensity.

Temperature and Humidity Readings:

• Temperature is displayed in Celsius (°C) or Fahrenheit (°F).
• Luftfugtighed vises som en procentdeltage of relative humidity (%RH).
• Note: Due to varying environmental conditions, actual measurement values for temperature and humidity may have a deviation of 0-15%, which is considered a normal range.

6. Sikkerhedsoplysninger og forholdsregler

To ensure safe and proper operation of your device, please observe the following precautions:

• Microphone Sensor: DO NOT touch or poke the Microphone Sensor. It is not a reset button.
• Rensning: DO NOT use chemicals or solvents to clean the product, as residual fumes may affect air quality readings. Use a soft, dry cloth for cleaning.
• Væsker: DO NOT place water or other liquids on or near the product to avoid electrical damage.
• Modification/Repair: Tillad IKKE uautoriseret modifikation eller reparation af dette produkt.
• Demontering: Denne skærm må IKKE adskilles eller skilles ad. Hvis du gør det, kan det beskadige produktet og ugyldiggøre garantien.
• Tiltænkt brug: This decibel meter is designed for indoor use only. Keep it in a stable indoor environment.

7. Vedligeholdelse

To maintain the accuracy and longevity of your device:

• Hold enheden ren ved at tørre den af ​​med en blød, tør klud.
