CHAPTER 4

Getting to Know Your Analyzer

Instantaneous Measured Parameters

• Instantaneous Time-weighted Sound Levels (L

– example: L

)

• Sound Pressure Levels (max levels once per second – example: L

(SPL))

• Instantaneous Peak Sound Levels (example: L

Cpeak,1s

)

• Instantaneous Weather data (requires a weather station connected)

• Instantaneous GPS data (requires a GPS device connected)

Note: See Appendix B for a comprehensive list of all parameters.

Sound Level Meter Software for 2250 Light BZ-7130 incorporates a simple user interface that

is easy to learn and uses intuitive data storage and recall. Comprehensive security features

mean no loss of data, even on accidental power-off. Sound Level Meter Software for 2250

Light BZ-7130 also provides connectivity between your PC and other sound analysis software.

This hand-held analyzer platform includes a range of optional software modules, that are

enabled through easily activated software license keys. The combination of software modules

and innovative hardware makes the instrument a dedicated solution for performing all your

high-precision measurement tasks. The following optional software modules are covered in this

manual:

4.2.2 Frequency Analysis Software

1/1-octave Frequency Analysis Software for 2250 Light BZ-7131

This software module allows real-time frequency measurements in 1/1-octave bands, making it

a simple matter to, for example, select suitable hearing protection, qualify noise from heat and

ventilation systems and assess tonality.

1/3-octave Frequency Analysis Software for 2250 Light BZ-7132

This software module allows real-time frequency measurements in 1/3-octave bands.

4.2.3 Logging Software for 2250 Light BZ-7133

This software module allows logging of broadband and spectral data

to obtain a time history

for later analysis, for example, for use in environmental noise as well as workplace noise

assessment. It allows free selection of up to 10 parameters to log at periods from 1 s to 24 h.

Results are logged directly to the SD memory card (or CF card if using hardware

versions 1 – 3).
