4.1. Включение/выключение питания
- Нажмите Власть button (usually marked with "Я" or a power symbol) to turn the meter on.
- Нажмите и удерживайте Власть Нажмите и удерживайте кнопку несколько секунд, чтобы выключить измерительный прибор.
- The meter features an auto-power-off function to conserve battery life.
4.2. A/C Weighting Selection
- Нажмите Кондиционер button to toggle between A-weighting and C-weighting.
- А-взвешивающий (dBA) is commonly used for environmental noise measurements and approximates the human ear's response.
- C-взвешивание (dBC) provides a flatter response, suitable for measuring peak sound levels or noise from machinery.
4.3. Fast/Slow Response Time
- Нажмите БЫСТРО МЕДЛЕННО button to select the desired response time.
- БЫСТРЫЙ response (125 ms) is suitable for capturing rapidly changing noise levels.
- МЕДЛЕННЫЙ response (1 second) provides an averaged reading for more stable noise sources.
4.4. MIN/MAX Function
- Нажмите МИН МАКС button to activate the minimum/maximum hold function.
- The display will show the highest (MAX) or lowest (MIN) sound level recorded since the function was activated.
- Press the button again to cycle through MAX, MIN, and normal measurement modes.
4.5 Выход переменного/постоянного тока
The meter provides AC and DC output jacks for connecting to external devices such as chart recorders, data loggers, or sound analysis equipment. Refer to the specifications section for output voltagе подробности.
5. Техническое обслуживание и калибровка
5.1. Уборка
To ensure optimal performance and longevity, keep the meter clean. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the microphone is free from dust and debris.
5.2. Замена батареи
When the low battery indicator appears on the display, replace the 9V battery as described in the "Setup and Battery Installation" section. Always dispose of used batteries responsibly.
5.3. Калибровка
For applications requiring high accuracy or regulatory compliance, periodic calibration is recommended. The Sper Scientific 850015 can be calibrated in compliance with OSHA standards using an optional Acoustical Calibrator (Model 850016). A N.I.S.T. traceable certificate of calibration is also available from Sper Scientific.
