Sound Level Meter Software - BZ 7222

SLM Module

All Type 2250s come with the Sound Level Meter Software enabled. This makes Type 2250 into a versatile broadband sound level meter; it complies with the latest international standard (IEC 61672.1) as well as previous international and national standards.

All quantities are measured at the same time. For example, A and C frequency weighted levels are measured simultaneously, and at the same time F, S and I time weightings are applied in parallel. In addition, Peak levels are measured. Full statistics are also computed on-the-fly Combine this with the dynamic range exceeding 120 dB and you will never miss a beat! You get all the parameters in one attempt, under-range is non-existent and you will have difficulties provoking an overload. The detailed list of available parameters can be found in the specifications section. You choose what you want on the display, but, at any time . during or after the measurement . all other parameters can be inspected and reported.

The standard package allows you to document your measurements with written notes and voice annotations. Notes are added using a virtual keyboard on the touch screen.

Voice annotations are recorded using a separate commentary microphone when the commentary pushbutton is pushed and held. Voice annotations and notes can be attached before, during and after the measurement. Spoken comments during the measurement should, of course, be made during a pause or with the microphone placed at a distance using an extension cable. These unique features allows you to document your measurement (where, when, how, etc.,) and always have this information attached to the measurement. Notes and voice annotations can be reviewed on the instrument itself or after the data has been transferred to a PC.

If Sound Recording Option BZ 7226 is also enabled, you can record all or part of the measured signal. This recording is safely stored with the measurement. Thus it is easy to document that measured levels are indeed related to a particular noise source under investigation.
