Betjeningsvejledning
1. Grundlæggende måling
- Tryk på MAGT for at tænde enheden.
- The display will show the current sound level in decibels (dB).
- Weighting (A/C): Brug A/C button to switch between A-weighting (for general noise measurement, mimicking human ear response) and C-weighting (for measuring peak sound pressure levels).
- Response Time (FAST/SLOW): Brug HURTIG LANGSOM button to select the desired response time. Fast response is suitable for rapidly changing noise, while slow response is for more stable noise levels.
- Valg af rækkevidde: The device features an automatic range selection from 30 to 130 dB. Manual range adjustment may also be available depending on the model's specific firmware.
- MAX/MIN Hold: Tryk på MAX/MIN button to display the maximum or minimum sound level recorded during a measurement session. Press again to cycle through modes or exit.
- Data Hold: Tryk på HOLDE knappen for at fryse den aktuelle aflæsning på displayet. Tryk igen for at slippe.
2. Datalogning
The SL-451 can record up to 32,000 measurements.
- Sørg for, at enheden er tændt.
- Tryk på REC button to start data logging. The "REC" indicator will appear on the display.
- Tryk på REC knappen igen for at stoppe logningen.
- To retrieve logged data, connect the device to a PC using the USB cable and open the installed software.
- Follow the software instructions to download, view, and analyze the recorded measurements. The software supports analysis according to standards like DIN 15905-5.
3. Kalibrering
For accurate measurements, periodic calibration is recommended. The device is calibratable.
- Use a standard sound calibrator (e.g., Voltcraft SLC-100, if available) to perform calibration.
- Refer to the specific instructions provided with your calibrator and the SL-451's detailed manual for the calibration procedure.
- Incorrect calibration can lead to inaccurate readings.
Opretholdelse
Rensning:
- Tør enheden af med en blød, tør klud.
- Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Keep the microphone clean and free of dust or debris.
Opbevaring:
- Når de ikke er i brug i længere perioder, skal batterierne fjernes for at forhindre lækage.
- Store the device in its carrying case in a cool, dry place.
Udskiftning af batteri:
Replace batteries when the low battery indicator appears on the display to ensure continuous operation and accurate readings.
Fejlfinding
