2. GENERAL DESCRIPTION
The instrument has the following functions:
Measurement of Sound Pressure Level (SPL).
Weighted frequency measurements through A or C curve.
Measurement carried out with FAST or SLOW integration.
Measurement of maximum and minimum values of SPL.
Analogue AC/DC output which can be used with external multimeters and/or
dataloggers.
Automatic range selection.
PC connec tion through software SoundLink for recording operations
On the instrument’s front panel there are function keys to select the above-mentioned
functions (see § 4.3). The measured value appears on the wide LCD display with the
indication of the measuring unit and of the enabled functions.
On the side of the instrument there are: the analogue AC/DC output, the terminal for the
connection of the external power supply with no use of the battery, the mini USB port for
