작동 지침

1. 기본 측정

를 누르세요 힘 버튼을 눌러 장치를 켭니다.
The display will show the current sound level in decibels (dB).
Weighting (A/C): 사용하세요 에어컨 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): 사용하세요 빠르다/느리다 button to select the desired response time. Fast response is suitable for rapidly changing noise, while slow response is for more stable noise levels.
범위 선택 : 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: 를 누르세요 최대/최소 button to display the maximum or minimum sound level recorded during a measurement session. Press again to cycle through modes or exit.
데이터 보유 : 를 누르세요 잡고 있다 버튼을 누르면 디스플레이에 현재 측정값이 고정됩니다. 다시 누르면 고정이 해제됩니다.

2. 데이터 로깅

The SL-451 can record up to 32,000 measurements.

장치의 전원이 켜져 있는지 확인합니다.
를 누르세요 기록 button to start data logging. The "REC" indicator will appear on the display.
를 누르세요 기록 로깅을 중지하려면 버튼을 다시 누르세요.
