1 General information and design
TangoTMis an integrating sound level meter designed according to DIN EN 61672-1:2003, accuracy class 1
and group Z. This manual refers to firmware version 1.44.
NOTICE! Tango may perform measurements that require an official verification of the
calibration and that are legally binding.
(type approval number: 21.21/12.04)
ATTENTION! If Tango is used for legally binding measurements, only original accessories
shall be used.
For performing legally binding measurements with Tango only the following accessories are admitted according to the type approval :
• Tango (907000.1)
• Calibrator Cal200 1/2” type1 PCB (800934.4)
• Calibrator Type 4231 B&K (800043.2)
• Windscreen W2 (800253.0)
Using Tango the following sound level values may be measured: LAF, L

1.1 Important notes
When measuring with the device, please consider the following notes:
• Use the device as described in this manual only.
• Despite of its robust design, protect the device from any unnecessary bumps and vibrations as well
as humidity and dirt.
• Do not touch or moisten the sensitive microphone membrane during work.
• Pay attention to the permissible temperatures for using the device.
• Always switch off the device after using.
, L
Cpeak
,
• Do not expose the device to excess temperature as for example in a car with direct sunlight.
• If necessary, clean the device carefully without using solvents.
• Do not disassemble the device. Do not try to repair the device in case of malfuntion. Such manipulation
will always cause the loss of warranty and major damages. Make a note of the occuring errors and
send us the device for repair.

1.2 Power supply
1.2 Power supply
The device is powered by two batteries of the type LR6A (nominal voltage 1.2 . . . 1.5 V, primary cell or
rechargeable). Via the according USB cable Tango can be powered by an external source. Therefor the
cable has to be connected to a PC or to the public power supply via the provided adapter. The USB access
is totally separated from the internal batteries, so that the batteries are not affected, but accumulators are
not recharged, too. For legally binding measurements Tango has to be powered by battery, disconnected
from the public power supply.
1.2.1 Replace batteries
The battery compartment is located on the back at the bottom of the device (figure 1.1 bzw. 1.2). Follow the
instructions below to replace the batteries:
• Move up the lock of the battery compartment.
• Remove the lid.
• Remove the discharged batteries.
• Insert the new batteries paying attention to the polarity (figure 1.2)
• Switch on the device and check the battery status on the display (figure 1.3.2).

not connected to external power supply at the same time.
The monitoring output is not approved for this.
Tango contains the following parts: detachable microphone with preamplifier, casing, display, keypad and battery compartment. Opening the device is only
necessary for replacing the batteries (figure 1.2.1).
At the bottom of the device the USB
socket is located for connecting the device to a PC (type mini five-pole). Next
to it there is a socket for a 3.5 mm
stereo jack. This monitoring output is used
to connect a headset for example, it is
not approved for legally binding measurements.
A detailed description of the display and keypad is given in the paragraphs 1.3.2 and 1.3.1.
Pay also attention to the notes given in paragraph 1.1.

Battery symbol
The symbol on the display shows the battery status. The following three stauses may be displayed:
• The battery is fully charged. A legally binding measurement may be performed.
• The battery is charged half. A legally binding measurement may be performed.
• The battery is discharged. A legally binding measurement may not be performed. The device will
automatically turn off if the batteries are not replaced.
1.4 Software installation
First Tango driver must be installed for that Tango is recognized via USB connection. Second Tango-Utilities
should be installed for configuration of Tango settings and export of data.
