Instruccions de funcionament
1. Mesura bàsica
- Turn on the device using the Poder botó.
- Point the microphone towards the sound source.
- The current noise level will be displayed in decibels (dB).
2. Frequency Weighting (dB(A), dB(C))
Utilitza el A/C button to switch between frequency weighting curves:
- dB (A): Simulates the human ear's response to sound, commonly used for environmental noise measurements.
- dB(C): Provides a flatter response, suitable for measuring peak sound pressure levels or low-frequency noise.
3. Time Weighting (Fast/Slow)
Premeu el botó RÀPID/LENT button to select the desired time weighting:
- FAST (125 ms): For measuring rapidly changing noise levels.
- LENT (1 segon): For measuring average noise levels over a longer period, suitable for stable noise sources.
4. Data Logging and PC Connection
The device features a long-term recording function with 16,000 memory points and real-time logging capabilities when connected to a PC.
- Internal Data Logging: Premeu el botó REGISTRAR button to start/stop internal data recording. The device can store up to 16,000 measurement points.
- Connexió de PC: Connect the device to a computer using the provided RS232 cable.
- Programari: Install the provided software on your PC. This software allows for real-time data display, analysis, and download of recorded data.
- Enviament de dades: Utilitza el ENVIAR DADES button to initiate data transfer to the connected PC.
