1 GENERAL INFORMATION AND DESIGN

1 General information and design

TangoTM is 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 ac-

cording 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, LAFmax, LAFmin, LAS, LASmax, LASmin, LCpeak,

LAeq, LAtm, LAtm-LAeq, LAE, LCpeak>nund LAFn. A detailed description of these values is given in table 1.2.

NOTICE! The number of the ﬁrmware version can be displayed (section 2.3.2).

1.1 Important notes

When measuring with the device, please consider the following notes:

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.

•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.

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).

1 GENERAL INFORMATION AND DESIGN

NOTICE! The device cannot be switched on without containing charged batteries,

i.e. you may not switch on the device connected to a PC via USB without

batteries.

ATTENTION! Changing the batteries causes loss of time and calibration data, if Tango is

not connected to external power supply at the same time.

1.3 Design

ATTENTION! For legally binding measurements Tango has to be powered only by battery.

The monitoring output is not approved for this.

Figure 1.3: Design of the device

Tango contains the following parts: de-

tachable microphone with preampliﬁer, cas-

ing, display, keypad and battery com-

partment. Opening the device is only

necessary for replacing the batteries (ﬁg-

ure 1.2.1).

At the bottom of the device the USB

socket is located for connecting the de-

vice 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 measure-

ments.

A detailed description of the display and key-

pad is given in the paragraphs 1.3.2 and 1.3.1.

Pay also attention to the notes given in para-

graph 1.1.
