3. Орнотуу жана Батареяны орнотуу
The Sper Scientific 850015 comes with a 9V battery included. Follow these steps to install or replace the battery:
- Аппараттын артындагы батарея бөлүкчөсүнүн капкагын табыңыз.
- Бөлүктү ачуу үчүн капкакты жылдырыңыз же ачыңыз.
- Туура полярдуулукту камсыз кылуу менен, 9V батарейканы батареянын кличкасына туташтырыңыз.
- Place the battery into the compartment and replace the cover, securing it firmly.
- Attach the windscreen to the microphone at the top of the meter. This helps reduce wind noise during measurements.

4.1. Күйгүзүү/өчүрүү
- басыңыз Күч button (usually marked with "Мен" or a power symbol) to turn the meter on.
- басып, кармап туруңуз Күч button for a few seconds to turn the meter off.
- The meter features an auto-power-off function to conserve battery life.
4.2. A/C Weighting Selection
- басыңыз A/C button to toggle between A-weighting and C-weighting.
- А-салмак салуу (dBA) is commonly used for environmental noise measurements and approximates the human ear's response.
- C-салмак салуу (dBC) provides a flatter response, suitable for measuring peak sound levels or noise from machinery.
4.3. Fast/Slow Response Time
- басыңыз ТЕЗ/ЖАЯН button to select the desired response time.
- ТЕЗ response (125 ms) is suitable for capturing rapidly changing noise levels.
- ЖАЯН response (1 second) provides an averaged reading for more stable noise sources.
4.4. MIN/MAX Function
- басыңыз MIN / MAX 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. AC/DC чыгышы
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 voltage деталдары.
5. Техникалык тейлөө жана калибрлөө
5.1. Тазалоо
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. Батареяны алмаштыруу
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. Калибрлөө
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.
