Main features of HS6258 environmental vibration and noise analyzer

The HS6258 environmental vibration analyzer is a new digital handheld intelligent measuring instrument. This instrument mainly measures the vibration acceleration level Lv (referred to as vibration level). The instrument adopts advanced digital detection and digital filtering technology. The vertical and horizontal frequency and time weights F (Fast) and S (Slow) are obtained through digital calculation methods, which have the advantages of high reliability, good stability, and wide dynamic range.

The performance of the instrument shall comply with the requirements of the old standard GB/T10071-1988 (ISO8041) or the new standard GB/T23716-2009 for Type 1 human response vibration meters and environmental vibration measuring instruments. The instrument also meets the requirements of the calibration regulation of JJG921-2021 Environmental Vibration Analyzer. The instrument has single group measurement and acquisition measurement functions, and the data can be stored in internal Flash or on an SD card.

Main features and parameters

1. Acceleration sensor: Sensitivity: 27.9mv/m/s-2

2. Frequency range: 1Hz~160Hz, lateral sensitivity ratio:<5%.

3. Measurement range: 50dB~140dB (with reference to 10-6 m/s2, the same below)

4. Frequency range: 1Hz~80Hz

5. Frequency weighting:

1) Old standard: Whole body vertical Z-frequency weighting, whole body horizontal X-Y frequency weighting, linear (unweighted) acceleration level.

2) New standard: Whole body vertical Wk frequency weighting, whole body horizontal Wd frequency weighting, linear (unweighted) acceleration level.

6. Time weighting: 1s (Fast), 8s (Slow)

7. Detector characteristics: true effective value, peak factor greater than 3.

8. Timing measurement time setting: Man (manually pre-set time), 10s, 1/5/10/15/20/30min, 1/8/24h.

9. Set clock: Provide year, month, day, hour, minute, and second. Shutdown and power outage do not affect operation.

10. Automatic measurement function: Lp, Leq, SD, Lmax, Lmin, LN (L95, L90, L50, L10, L5), etc.

11. Automatic storage of measurement data: When using internal Flash storage, 800 sets of measurements can be taken per group; Collect and measure 200 sets. Internal Flash data storage uses a cyclic approach, where when the maximum number of data groups is reached,

12. After deleting the previous data, store it in new data. When using an SD card (up to 32GB) for storage, data files are managed in FAT32 format, with each file being 4GB in size. The number of measurement groups is determined based on the file capacity.
