Overview
DB30-6226F noise spectrum analyzer is a general-purpose sound level meter, which can measure exponential time weighted sound level, time average sound level, sound exposure and cumulative percentage sound level. It is suitable for industrial environment noise measurement, environment noise census, especially for noise spectrum analysis, widely used in environment, machinery, transportation, ships and other fields, serving industrial environmental protection, construction, health, teaching and research departments.
Features
The performance meets the requirements of GB/T 3785, IEC 61672-2002 (2-level sound level meter), JJG 188-2017 standards, and IEC1260 and GB/T 3241-1998 for octave filters.
2. Built-in 1/1 octave and 1/3 octave filters, support manual and automatic sweep measurement, automatic sweep data can save 12 groups.
3. With integral and statistical functions, a single group of measurement up to 800 groups, the whole time measurement up to 6 days, data can be accessed and printed.
4. There are three gears for time weighing: fast (F), slow (S), and pulse (I).
5. Adopt Digital Detection Technology to Improve Stability and Reliability.
6. Large screen display, clear and intuitive, with dynamic scale display.
7. Optional Bluetooth printer for data printing.
8. Support USB cable and Bluetooth data output, communicate with PC.
Principle
The analyzer collects acoustic signals through the built-in test capacitor microphone, and uses digital detection technology to process the signals to realize Frequency weighting (A, C, linear) and Time weighting (fast, slow, pulse) measurement. Built-in octave filter for spectrum analysis, automatic or manual frequency sweep, data can be integrated, counted and stored.
Applications
Environment, machinery, transportation, shipbuilding, industrial environmental protection, construction, health, teaching and research
Standards
GB/T 3785、IEC 61672-2002、JJG 188-2017、IEC1260、GB/T 3241-1998
Steps
1. Install 5 AA batteries or connect a 5V external power supply.
2. Select Measurement mode (such as automatic or manual sweep).
3. Set the time weighting gear (fast, slow, or pulse).
4. Perform sound level measurement, data is automatically saved or manually recorded.
5. Output data via USB or Bluetooth, optional printing.
Notice
• Operating conditions are -10~ 50 ° C to ensure operation at the appropriate temperature.
• Use 5 AA batteries or 5V external power supply to avoid overvoltage.
• Measurement range 30dB~ 130dB, divided into three levels of control, pay attention to range selection.
• Data storage is limited, up to 800 sets of measurements in a single group, and the maximum measurement time is 6 days.
• Make sure the connection is stable when the interface is output to avoid data loss.
