Betjeningsvejledning

1. Grundlæggende måling

1. Tænd enheden ved hjælp af Magt knap.
2. Point the microphone towards the sound source.
3. The current noise level will be displayed in decibels (dB).

2. Frequency Weighting (dB(A), dB(C))

Brug 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)

Tryk på HURTIG LANGSOM button to select the desired time weighting:

• FAST (125 ms): For measuring rapidly changing noise levels.
• SLOW (1 second): 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.

1. Internal Data Logging: Tryk på OPTAGE button to start/stop internal data recording. The device can store up to 16,000 measurement points.
2. PC-forbindelse: Connect the device to a computer using the provided RS232 cable.

3. Software: Install the provided software on your PC. This software allows for real-time data display, analysis, and download of recorded data.
4. Afsendelse af data: Brug SEND DATA button to initiate data transfer to the connected PC.

5. Kalibrering

The device can be calibrated and adjusted using a standard noise level calibrator (94 dB / 1 kHz). Refer to the calibrator's instructions for the specific calibration procedure.

Opretholdelse

1. Rensning

• Tør enheden c afasinmed en blød, tør klud.
• Brug ikke slibende rengøringsmidler eller opløsningsmidler.
• Ensure the microphone is kept clean and free of dust or debris.

2. Opbevaring

When not in use, store the SoundTest-Master in its protective case in a cool, dry place, away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
