• Loudness Unit (dB/SONE): Button to switch between decibel and SONE units.
• Одељак за батерије: Located at the rear, holds the AAA batteries.

3. Кључне карактеристике

• Accurate and Sensitive Measurement: Utilizes a high-quality AD636 chip and an electric condenser microphone for precise sound level monitoring from 30 to 130 dB with an accuracy of +/-1.5 dB and 0.1 dB resolution.
• Fast and Slow Response Rates:
  • Fast Response (0.125s): Ideal for general environmental measurements and quickly changing noise levels.
  • Slow Response (1s): Suitable for environmental measurements with relatively stable noise levels or for averaging fluctuating sounds.
• A/C Weighting Network Selection:
  • A-Weighting: Simulates human hearing characteristics, suitable for ambient noise detection.
  • C-Weighting: Measures the actual sound level, suitable for sound pressure analysis of machine motors and mechanical noise.
• Data Hold and MAX Functions: Allows freezing the current reading and displaying the maximum recorded value.
• ЛЦД екран са позадинским осветљењем: Ensures clear visibility of readings in various lighting conditions, with an auto power-off function for energy saving.
• Дизајн против клизања: Composite material injection molding process with an anti-drop structure for durability and ease of handling.

4.2 Инсталација батерије

1. Пронађите одељак за батерију на задњој страни уређаја.
2. Користите мали одвијач са крстастим наставком да бисте отпустили завртањ који причвршћује поклопац батерије.
3. Скините поклопац батерије.
4. Insert four (4) AAA batteries, ensuring correct polarity (+/-).
5. Вратите поклопац батерије и затегните завртањ.

Напомена: The device requires 4 AAA batteries. Ensure they are inserted correctly for proper operation.

5. Упутство за употребу

5.1 Укључивање/искључивање

Притисните тастер ОН-ОФФ button (green power symbol) to turn the meter on. Press it again to turn the meter off.

5.2 Основна мерења

Once powered on, the meter will immediately begin displaying the current sound level in decibels (dB). Ensure the microphone is pointed towards the sound source.

5.3 A/C Weighting Selection

Притисните тастер А/Ц button to toggle between A-weighting and C-weighting modes. The selected mode will be indicated on the LCD.

• A-Weighting Mode: Simulates the human ear's response to sound. Use this for general environmental noise measurements, such as in offices, residential areas, or for assessing noise exposure.

5.4 Fast/Slow Response Time

Притисните тастер БРЗО СПОРО button to switch between fast and slow response times.

• БРЗО: Responds quickly to changes in sound level (0.125 seconds). Useful for capturing transient noises or rapidly fluctuating sounds.
• СПОРО: Provides a more stable reading by averaging the sound level over a longer period (1 second). Ideal for measuring average noise levels or sounds that are relatively constant.

5.5 Data Hold (H)

Притисните тастер H button to freeze the current reading on the display. Press it again to release the hold and resume live measurement.

5.6 Maximum (MAX) Measurement

Притисните тастер МАКС button to display the maximum sound level recorded since the meter was powered on or since the MAX function was last reset. Press it again to exit MAX mode.

5.7 Позадинско осветљење

Притисните тастер Позадинско осветљење button (sun symbol) to turn the LCD backlight on or off. The backlight will automatically turn off after a period of inactivity to conserve battery power.

5.8 Unit Selection (dB/SONE)

Притисните тастер dB/SONE button to switch the display unit between decibels (dB) and SONE.
