Auto-Power-Off
: the instrument is provided with the auto-power-off function that auto-
matically switches it off after 5 minutes the instrument is in STOP mode and no key has
been pressed. Before switching off, the instrument will make a series of beep: press any
key to prevent the instrument shutting off. The function is active if this menu item is "ON".
If you set Auto-Power-Off = OFF, the instrument will not automatically shut off.
In this
case the battery symbol will flash even if batteries are fully charged.

Baud Rate
:
Baud Rate
: this parameter and the next ones define the properties of the serial
connection. Selectable baud rate values go from a minimum of 300 to a maximum of
230400 baud. The higher is the value, the faster is the connection; therefore,
when possible
,
it is suggested to select the highest available value to speed up data transfer as much as pos-
sible. If the instrument is connected to a printer with RS232 serial input or with a seri-
al/parallel converter, the value to be set is the one provided by the printer manufacturer.
WARNING: When you use the serial interface, the communication between instru-
ment and computer (or printer with serial input) works only if the instrument and PC
(or device) baud rates are the same. Take care of this note when using data transfer
programs requiring a manual configuration of the serial port parameters, such as, i.e.
HyperTerminal. The NoiseStudio program, combined with the HD2010UC automati-
cally sets the serial port, so that no action by the operator is required.
•
RS232 Bits
:
(non-modifiable parameter)
number of bits of which transferred data are made
up, the value is 8.
•
RS232 Stop Bits
:
(non-modifiable parameter)
stop bit, the value is 2.
•
RS232
Parity
:
(non-modifiable parameter)
parity bit, the value is: none (OFF).
•
Serial Device
:
identifies the device connected to the serial port.
The connection possibilities are:
PRINTER: connection to a printer with RS232 input
RS232:
connection to a PC equipped with RS232 port (physical)
MODEM: connection to a modem with RS232 input RS232 (see Connection to a mo-
USB:
connection to a PC by USB port (see “CONNECTION TO A PC WITH
USB INTERFACE” on page 68)
MC:
connection to optional module HD2010MC for SD memory card recording
(see paragraph on page 71)

EASUREMENTS
The
Measurement
item includes the acquisition general parameters.
•
Input Gain
: with Input Gain = 0 the measuring range upper limit equals 140dB, and as
much as the input gain increases the maximum measurable level decreases correspondingly
(see page 74). Select the proper gain according to the level of sound to be.
•
Integration interval
: Once this time has been reached, the instrument automatically
switches to HOLD, interrupting display update. It can be set from a minimum of 1s to a
maximum of 99 hours. When continuous recording is activated, the integration time acts
like a timer for data acquisition, stopping automatically the measurement when the time is
elapsed. If set to 0s, the timer is disabled and the integration becomes continuous.
•
Report Time
: report parameters are integrated over intervals corresponding to the set time.
At the beginning of every interval report parameters are automatically cleared. Report time
can be set to: 1, 2, 5, 10, 20 and 30 seconds, 1, 2, 5, 10, 20, 30 minutes and 1 hour. A re-
