Suidhich
1. Cumhachd a thoirt don inneal
The SL-451 can be powered by batteries or an external power adapter.
Stàladh bataraidh:
- Fosgail an còmhdach roinn bataraidh air cùl an inneil.
- Cuir a-steach na bataraidhean a tha a dhìth, a’ cumail sùil air a’ phòlarachd cheart.
- Dùin an còmhdach roinn bataraidh gu tèarainte.
Cumhachd a-muigh:
Ceangail an inneal-atharrachaidh cumhachd a tha air a thoirt seachad ri cuir a-steach cumhachd an uidheim agus an uairsin ri socaid cumhachd iomchaidh.
2. Ceangal Micreofon
The device comes with a detachable microphone and an extension cable.
- For direct use, ensure the microphone is securely attached to the main unit.
- For remote measurements, connect the microphone to one end of the 3-meter extension cable and the other end of the cable to the device's microphone input.
- Always use the foam windscreen on the microphone to minimize wind noise interference.
3. Software Installation (for Data Logging)
To utilize the data logging and analysis features, install the provided PC software.
- Cuir an CD bathar-bog a-steach do dhràibh CD/DVD a’ choimpiutair agad.
- Lean an stiùireadh air-sgrion gus am bathar-bog a stàladh.
- After installation, connect the SL-451 to your computer using the supplied USB cable.
- The software should automatically detect the device. If not, refer to the software's help documentation for troubleshooting connection issues.
Stiùireadh Obrachaidh
1. Tomhas Bunasach
- Brùth an CUMHACHD putan gus an inneal a thionndadh.
- The display will show the current sound level in decibels (dB).
- Weighting (A/C): Cleachd an 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): Cleachd an LUATH/SLOW button to select the desired response time. Fast response is suitable for rapidly changing noise, while slow response is for more stable noise levels.
- Taghadh Raon: 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: Brùth an MAX/MIN button to display the maximum or minimum sound level recorded during a measurement session. Press again to cycle through modes or exit.
- Cumail dàta: Brùth an LAOIDH putan gus an leughadh làithreach air an taisbeanadh a reothadh. Brùth a-rithist gus a leigeil ma sgaoil.
2. Logadh Dàta
The SL-451 can record up to 32,000 measurements.
- Dèan cinnteach gu bheil cumhachd aig an inneal.
- Brùth an REC button to start data logging. The "REC" indicator will appear on the display.
- Brùth an REC putan a-rithist gus stad a chuir air logadh.
- 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. Calabradh
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.
