The Benetech GT1355B Decibel Meter, a compact and ergonomic device for sound level measurement.
The GT1355B is designed to be lightweight and portable, making it easy to carry and use in various locations.
- A/C Weighted Measurement: The decibel meter utilizes a condenser microphone to accurately measure sound levels from 30 to 130 dB (A) and 35 to 130 dB (C), with an accuracy of ±1.5 dB. It covers a frequency range from 31.5 Hz to 8,500 Hz.

- Real-Time Monitoring & Data Recording: The SPL meter can store up to 43,000 sets of data. Data can be imported to a PC via the USB port for real-time sampling, analysis, downloading, printing charts, and deletion. The device also allows setting date, automatic shutdown time, and features a low battery indicator.
The device supports saving up to 43,000 sets of data, which can be managed via PC connection.
- Long-Lasting Battery & Portability: Equipped with a non-slip rubber grip, the meter is easy to handle. It features 1/4-inch mounting threads for tripod attachment, allowing for extended monitoring. A 1.5-hour charge provides up to 8 hours of standby time.
The decibel meter charges via a USB-C port, offering quick charging and extended duration.
The device can be mounted on a stand for continuous monitoring, as shown with a small tripod.

1. Ngba agbara ẹrọ
Before first use, fully charge the decibel meter. Connect the provided USB cable to the Type-C port on the device and the other end to a standard USB power adapter (not included) or a computer's USB port. The battery indicator on the LCD screen will show charging status. A full charge takes approximately 1.5 hours and provides up to 8 hours of standby time.
2. Agbara akọkọ Lori
Press and hold the red power button (usually located at the bottom center of the control panel) for a few seconds until the LCD screen illuminates.
3. Eto Ọjọ ati Aago
Upon first power-on or after a long period of disuse, you may need to set the date and time. Tap the red power button once the device is on to cycle through various settings. Use the navigation buttons (left/right/up/down) to adjust values and the red button to confirm.
The device offers various settings including LCD backlight, low battery indicator, auto power off, and date & time settings.

- To turn on: Press and hold the red power button until the screen lights up.
- To turn off: Press and hold the red power button until the screen turns off.
2. Measurement Modes (A/C Weighting & Fast/Slow)
The GT1355B supports both A and C frequency weighting, and Fast and Slow time weighting.
- A-Weighting: Simulates the human ear's response to sound, commonly used for environmental noise measurements.
- C-Weighting: Provides a flatter response, suitable for measuring the true sound level of machinery or peak noise.
- Fast Time Weighting: Responds quickly to changes in sound level, ideal for fluctuating or unsteady noise.
- Slow Time Weighting: Provides an averaged reading, suitable for measuring steady-state noise.
Use the "A/C" button to switch between A and C weighting, and the "F/S" button to switch between Fast and Slow time weighting.

3. Kíkà Ìfihàn náà
The LCD screen displays the current decibel reading, along with a real-time graph of sound level changes. It also shows minimum (min) and maximum (max) values recorded during the current measurement session.
4. Visual Alarm Function
The device features a visual alarm system that changes the screen color and activates an indicator light when sound levels exceed predefined thresholds.
- Setting Alarm Thresholds: Navigate to the alarm settings menu using the control buttons. You can set a low alarm value (e.g., yellow alert) and a high alarm value (e.g., red alert). Ensure the high alarm value is greater than the low alarm value.
- Itọkasi itaniji:
- Blue Screen: Sound level is below both alarm thresholds.
- Yellow Screen: Sound level is between the low and high alarm thresholds.
- Red Screen: Sound level exceeds the high alarm threshold.
