Overview
The DUBAN DB30-6226ILEQ Pulse Integrating Sound Level Meter is a multi-functional sound level measuring instrument that can be used as a general-purpose sound level meter for measurement of exponential time weight sound level and as a pulse sound level meter. Its performance meets the requirements of GB/T 3785, IEC 61672-2002 for level 1 sound level meters and JJG 188-2017 standards, and is suitable for various industrial environment noise measurement and environment noise census.
Features
1. Meet the performance requirements of GB/T 3785 and IEC 61672-2002 standards for 2-level sound level meters, and comply with JJG 188-2017 standards
2.With integral and statistical functions, single measurement data can be stored up to 800 groups, continuous measurement up to 6 days
3. Provide fast (F), slow (S) and pulse (I) three time weighting gear options
4. Adopt Digital Detection Technology to Significantly Improve Instrument Stability and Reliability
5. Equipped with large screen display, clear and intuitive information, support dynamic scale display
6. Optional Bluetooth printer, easy to print measurement data
7. Support via USB cable and Bluetooth data output, can communicate with PC and data transmission analysis
Principle
The pulse integrator sound level meter collects sound signals through φ 12.7mm test capacitor microphone, uses digital detection technology to process signals, provides A, C and linear frequency weighting options, and performs measurement in the 20Hz-8kHz Frequency range. Measurement range of 30dB~ 130dB is realized by automatic or manual range control.
Applications
Environment, machinery, transportation, shipbuilding, industrial environmental protection, construction, teaching and research
Standards
GB/T 3785、IEC 61672-2002、JJG 188-2017、IEC61672
Steps
1. Install 5 AA batteries or connect 5V external power supply
2. Select the desired time weighting gear (Fast F, Slow S, or Pulse I)
3. Set the range control mode (automatic or manual third gear)
4. Start measurement, the instrument automatically stores data
5. View the measurement results through the large screen or connect to the PC for data transmission analysis
6. Optional Bluetooth printer for data printing
Notice
• Temperature range -10~ 50 ℃
• Power supply voltage meets requirements (5 AA batteries or 5V external power supply)
• Confirm instrument accuracy to level 2 before measurement
• Note that the linear range of the instrument is greater than 60dB
When storing data, pay attention to a single measurement up to 800 groups, continuous measurement up to 6 days
• Ensure stable connection when using USB or Bluetooth output
