• Батарея бөлүмү: Located at the rear, holds the AAA batteries.

3. Негизги өзгөчөлүктөрү

• 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.
• Арткы жарыктуу LCD экран: Ensures clear visibility of readings in various lighting conditions, with an auto power-off function for energy saving.
• Слипке каршы дизайн: Composite material injection molding process with an anti-drop structure for durability and ease of handling.

4.2 Батареяны орнотуу

1. Аппараттын артындагы батарея бөлүкчөсүн табыңыз.
2. Use a small Phillips head screwdriver to loosen the screw securing the battery cover.
3. Батареянын капкагын алып салыңыз.
4. Туура полярдуулукту (+/-) камсыз кылып, төрт (4) AAA батарейкасын салыңыз.
5. Батарейканын капкагын ордуна коюп, бурамасын бекемдеңиз.

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

5. Иштөө нускамалары

5.1 Күйгүзүү/өчүрүү

басыңыз КҮЙГҮЗҮҮ ӨЧҮРҮҮ button (green power symbol) to turn the meter on. Press it again to turn the meter off.

5.2 Негизги өлчөө

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.
