Features

Precise Measurement: Measurement range from 30 dB to 130 dB with an accuracy of ±2.0 dB.
A/C Weighting:
- A-weighting: Simulates human ear frequency characteristics for low-intensity noise, suitable for ambient noise detection.
- C-weighting: Simulates human ear frequency characteristics for high-intensity sounds, suitable for analyzing sound pressure from engines and machinery.
Fast/Slow Response:
- Fast Response (0.125s): More sensitive, ideal for general environmental measurements.
- Slow Response (1s): More stable, used for environments with significant sound level changes.
Digital LCD Display: 4-digit backlit LCD with 0.1 dB resolution for clear readings, even in low light. Includes a low battery indicator.
MAX Value Hold: Function to retain the maximum recorded noise level.
Portable Design: Lightweight and easy to carry for various applications.

Operating Instructions

Power On/Off

To turn on the device, press the Power Switch button (marked with a power symbol).
To turn off the device, press and hold the Power Switch button for a few seconds.

Basic Measurement

Turn on the device. The LCD will display the current sound level.
Point the microphone towards the sound source you wish to measure.
Read the decibel (dB) value displayed on the LCD screen.

A/C Weighting Selection

Press the A/C button to toggle between A-weighted and C-weighted measurement modes.
The selected mode (A or C) will be indicated on the LCD.

Fast/Slow Response and MAX Hold

Press the F/S MAX button to cycle through Fast response, Slow response, and MAX hold functions.
The current response time (FAST or SLOW) will be displayed.
When MAX hold is active, the display will show "MAX" and hold the highest decibel reading until reset or a higher value is detected.

Maintenance

General Care

Keep the device clean and dry. Wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents.
Avoid exposing the device to extreme temperatures, high humidity, or direct sunlight.
Protect the microphone from dust and debris. Always use the wind-resistant foam ball during operation and storage.
Store the device in its protective bag when not in use.

Battery Replacement

When the low battery icon appears on the LCD, replace the two AAA batteries promptly to ensure accurate measurements and continuous operation. Refer to the "Battery Installation" section for detailed steps.

Troubleshooting

Problem	Possible Cause	Solution
Device does not power on.	Batteries are dead or incorrectly installed. Power button not pressed correctly.	Replace batteries with new AAA batteries, ensuring correct polarity. Press and hold the power button firmly.
Inaccurate readings.	Microphone obstructed or damaged. Incorrect A/C weighting or Fast/Slow response selected for the environment. External interference (e.g., strong electromagnetic fields).	Ensure microphone is clear and foam ball is properly placed. Select appropriate A/C weighting and Fast/Slow response based on the noise type. Move away from potential sources of interference.
LCD display is dim or blank.	Low battery. Device malfunction.	Replace batteries. If problem persists after battery replacement, contact customer support.
