2. Подешавање
2.1 Инсталација батерије
- Пронађите поклопац одељка за батерију на задњој страни уређаја.
- Померите или откопчајте поклопац да бисте отворили одељак.
- Уметните две (2) ААА батерије од 1.5 V, водећи рачуна о исправном поларитету (+/-).
- Вратите поклопац одељка за батерије безбедно.
Note: Batteries are included with the device. Please ensure they are installed correctly before first use.
2.2 Почетно укључивање
After installing the batteries, press the power switch (labeled '3' in Figure 1) to turn on the device. The LCD display will illuminate, and the device will be ready for measurement.
3. Упутство за употребу
3.1 Укључивање/искључивање
- Да бисте укључили: Притисните дугме Прекидач за напајање.
- Да бисте искључили: Притисните дугме Прекидач за напајање again. The device also features an automatic power-off function to conserve battery life.
3.2 Мерења
Hold the sound level meter with the microphone (1) pointed towards the sound source. The current decibel level will be displayed on the LCD screen (6).
3.3 FAST/SLOW Time Weighting
Притисните тастер БРЗО СПОРО button (4) to select the desired time weighting:
- ФАСТ: Measures sound levels with a 125ms time constant, suitable for capturing sudden noise changes.
- СЛОВ: Measures sound levels with a 1-second time constant, suitable for averaging fluctuating noise levels.
3.4 MAX/MIN Value Display
Притисните тастер МАКС/МИН button (5) to cycle through the display modes:
- Current real-time measurement.
- Maximum (MAX) decibel value recorded since power-on.
- Minimum (MIN) decibel value recorded since power-on.
3.5 Аутоматско позадинско осветљење
The device features an automatic LCD backlight sensor (2). The backlight will automatically illuminate in low-light conditions, making the display clearer and easier to read, especially at night or in dim environments.
Figure 3: The automatic backlight sensor ensures clear readability of the LCD display in various lighting conditions.
3.6 Windscreen Usage
When measuring in environments with wind speeds exceeding 10 meters per second, it is recommended to use a wind cover (MIC Enclosures Wind, 1) over the microphone. This helps to reduce wind noise interference and improve measurement accuracy.
3.7 Decibel Level Interpretation

4. Одржавање
4.1 Чишћење
To clean the device, use a soft, dry cloth. Do not use abrasive cleaners or solvents. Avoid immersing the meter in water or exposing it to excessive moisture.
4.2 Замена батерије
When the battery indicator on the LCD display shows low power, replace the batteries promptly to ensure accurate measurements. Follow the battery installation steps in Section 2.1.
4.3 Складиштење
When not in use for extended periods, remove the batteries from the device. Store the sound level meter in a cool, dry place with a storage temperature between -10°C and 60°C and relative humidity between 10% and 70%.
КСНУМКС. Решавање проблема
5.1 Нетачна очитавања
- Check for wind interference: If measuring outdoors or in windy conditions, ensure the wind cover is properly installed.
- Ниво батерије: Low batteries can affect performance. Replace batteries if the indicator shows low power.
- Услови околине: Ensure operating temperature and humidity are within specified ranges (0~40°C, 10~80% RH).
- Device malfunction: If readings remain consistently inaccurate despite checking the above, the device may require service. Contact customer support.
5.2 Уређај се не укључује
- Инсталација батерије: Verify that batteries are inserted correctly with the right polarity.
