be used as an additional external power supply; the power supply must provide
5 V/1 A.
USB Disk Mode: It enables a direct interference in the files stored in the mi-
croSD card; it does not require driver installation.
The miniUSB port is detected by the computer as a serial port (virtual serial port,
driver installation required), and the communication with the sound level meter is
via the RS-232 interface; further information – see section RS-2325 Data Ex-
change Protocol.
☆ Hint: The power supply must provide a current of minimum 1 A, and the
cable must ensure the flow of such current (do not use ferrite balls for
power supply). Choose the operating mode after connecting the device to the
computer. Otherwise the USB port may not be detected by the computer. If you
choose the modem mode, a simultaneous operation of the miniUSB and RS-
232 ports is impossible.
MicroSD card:
MicroSD card socket: used to connect the microSD card to save SWN, OCT and
CSD files. We recommend using a card reader, not the USB Disk Mode, for mi-
croUSB card formatting. The microSD card delivered with the sound level meter
is pre-formatted.
☆ Hint: When inserting the microSD card, hold it face front (anti-scratch protec-
tion).
RS-232:
The socket can be used as a standard RS-232 interface in the remote mode
and to connect a thermal printer in the printer mode. Detailed information, see
4.6.3 Printer and 5. RS-232 Data Exchange Protocol.
TRIGGER:
Trigger input with a standard 3.5 mm headphone socket. Detailed information,
see 4.4.4 Trigger.
DC OUT:
DC output with a standard 3.5 mm headphone socket. Detailed information, see
4.6.2 DC OUT.
AC OUT:
AC output with a standard 3.5 mm headphone socket. Detailed information, see
4.6.1 AC OUT.

2.5 Battery

We recommend using 4 alkaline batteries (LR6/AA/AM3); consider the battery polar-
ity (+/-) and marking in the battery container. Do not use old and new batteries at the
same time. Take out the batteries if the device is not used. The total voltage at 4 bat-
tery cells should not exceed 14 V, otherwise the sound level meter may get dam-
aged.
Practical tests have shown that 4 alkaline battery cells are sufficient for almost 10
operating hours (depending on the batteries). If you use Eneloop BK-3HCCA/4BC
batteries (rated capacity: 2,450 mAh), the sound level meter can operate continu-
