PICCOLO PC OPERATION
SETUP MENU
Time Setup
At start-up, the Time & Date on the Piccolo is automatically verified and adjusted if the clock’s difference
is greater than 5 minutes.
The Time & Date can be manually synchronized with the PC by right-clicking on the Time & Date field.
Note: If some stored data in the Piccolo do not have the proper time reference or are corrupted, the
software application will request to save the current data in a file before erasing the data in the
Piccolo’s memory and setting the current Time & Date.
Measurement parameters Setup
Select the desired acoustical measurement parameters:
 Frequency weighting: dB(A) or dB(C)
 Time response: SLOW (1 sec.) or FAST (1/8 sec.)
 LEQ averaging time:
A selection of averaging times and a custom time are available for both Manual and AutoStore
measurement modes.
1 sec
(AutoStore Only)
10 sec 1 min 5 min 10 min 30 min 1 h 8 h 24 h
Custom
Note: When the averaging process is running, (the AVG indicator is displayed on the LCD), measurement
parameters cannot be modified on the Setup menu.
Storage Setup
Data Selection
Select the results to be stored: LMAX, LMIN, LEQ (& SEL), and/or L% using the check boxes.
Record Time Available varies with the Leq Averaging Period and the selected data to be stored. For more
recording space, unselect data types. L% is by far the data that uses the most memory. When L% is used,
reducing the Resolution will allow more data storage space.
For an averaging period of 1 hour, storing all the data with a resolution of 2.5 dB for L% allows
approximately 12 days of measurements. If only LMAX, LMIN and LEQ data are stored, the total
recording time would be up to 142 days

. The recording space varies greatly as a function of stored data
and the averaging period.
Erasing data
When the meter’s memory is full, the LCD will display the memory full indicator.
Use the Clear All action button to clear memory space. Before erasing memory, if desired, retrieve the
current data in the memory using the Data Processing menu.

The Low Battery event would normally occurs before the Memory Full event.
