3. Instruccions de funcionament
3.1 Mesura bàsica
- After powering on, the device will immediately begin measuring sound levels, temperature, and humidity.
- Hold the meter in the area where you wish to measure noise. Ensure the microphone is pointed towards the sound source.
- Read the current sound pressure level (SPL), temperature, and humidity values on the LCD.
3.2 Selecció del mode
- Premeu el botó MODE button to cycle through different measurement modes, such as A-weighting and C-weighting.
- A-weighting is commonly used for general noise measurements as it mimics the human ear's response.
- C-weighting is more suitable for measuring peak sound pressure levels and low-frequency noise.
3.3 Dynamic Characteristic (Fast/Slow)
- Premeu el botó F/S RECORD button (short press) to switch between Fast and Slow response times.
- Ràpid: Suitable for measuring rapidly changing noise levels.
- Lent: Suitable for measuring relatively stable noise levels.
3.4 Data Recording and Storage
- To initiate data recording, press and hold the F/S RECORD button. The display will indicate that recording has started.
- Per deixar de gravar, manteniu premut el botó F/S RECORD botó de nou.
- The device can store up to 15,000 groups of data.
3.5 Data Transfer to Computer
- Connect the meter to a computer using a USB cable via the USB port.
- Use the provided software (if applicable, refer to software manual) to download recorded data, perform real-time sampling analysis, and print graphs or data reports.

3.6 Selecció de la unitat de temperatura
- Premeu el botó ℃ / ℉ button to switch the temperature display between Celsius (℃) and Fahrenheit (℉).
4. Manteniment
- Neteja: Feu servir un drap suau i sec per netejar el dispositiu. No utilitzeu productes de neteja abrasius ni dissolvents.
- Cura del micròfon: Keep the microphone clean and free from dust or debris. Always use the foam windscreen to protect it.
- Emmagatzematge: Quan no l'utilitzeu durant períodes prolongats, traieu les piles per evitar fuites. Guardeu el dispositiu en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
- Calibració: For professional applications requiring high accuracy, periodic calibration by a qualified service center is recommended. The calibrated sound source is 94dB @ 1KHz.
