Instruction manual

Outline

Communication with a computer is possible via the built-in I/O connector

and USB connector. Because the USB connector conforms to storage speci-

 cations, the unit will be recognized as a removable disk when connected

to a computer. This allows transfer of data from the SD memory card to the

computer without having to remove the SD memory card from the unit.

The RS-232C interface allows sending measurement data to a printer.

Various optional programs allow users to add the following functions: long-

time, continuous data recording to SD memory card, waveform recording,

and comparator output. Also, various measurements are supported including

octave and 1/3 octave band real-time analyses, FFT analysis, and additional

measurements such as time weighting I (impulse).

In addition to the measurements of sound level, equivalent continuous sound

level and maximum/minimum sound level, the unit can measure percentile

sound level and sound exposure level. Up to 1000 measurement results can

be stored in the main unit.
