1.3 Power supply
Tango_Plus is powered by two batteries of the type LR6/AA (nominal voltage 1.2 . . . 1.5 V, primary cell
or rechargeable). So it can run for at least 40 hours. Via the according USB cable Tango_Plus can be
powered auxilliarily by an external source, but batteries must always be inserted. For that the cable has to be
connected to a PC or to the public power supply via a suitable adapter. The USB access is totally separated
from the internal batteries, so that the batteries are not affected, but accumulators are not recharged, too.
ATTENTION! For legally binding measurements Tango_Plus has to be powered by bat-
tery, disconnected from the public power supply.
1.3.1 Replace batteries
The battery compartment is located on the back at the bottom of the device (figure 1.1).

The Third Octave Display shows a
spectrum in the main part with live values
as bars and Leq values as roof top. Via
left/right keys the spectral cursor can be
moved to select signle bands. The band
level and the frequency are displayed
above the graph as well as the measu-
rement duration. On the left LAF and LCF
are displayed as bars. The bottom shows
numerically one sound level value, which
can be switched using the up/down keys.

2.3.4 Setup Tab
The Setup tab of Tango-Utilities (figure 2.6) provides the configuration of Tango_Plus for a measurement.
In the column Display use the check boxes to enable individual values and comboboxes to set the graphic
refresh rate for display. Several values offer optional parameters, which you may set in the column Options.
By the buttons Open and Save you may open a configuration from the PC or save the current one to it. The
same can be done by using the menu points File →"‘Open Configuration"’ and File →"‘Save Configu-
ration As"’. The current configuration is transmitted to Tango_Plus by clicking on Apply .
In the column Storage the correspondig storage conditions are adjusted. The storage can be turned off,
limited to one finish result or done in regular intervals. For the interval time span several values are provided
from 62,5 ms up to 60 min depending on the measurement value. Even if the interval storage is selected a
finish result over the whole measurement time is calculated and stored additionally. This would always be
saved, even if the intervall storage would have been aborted because of full memory. In this case the record
symbol would stop blinking.
NOTICE! For the interval storage of the percentiles only the same interval time span
can be selected.
If Synchronisation is enabled, the interval storage will be synchronised with the full hours of day time. So
every full hour the current interval is closed and a new one is started. The clock is set every time, when
connecting Tango_Plus to Tango-Utilities.

This tab provides the export of time histories of level or spectra to the Excel compatible csv format. To use
it, check the “Enable Export file” box. You may specify the name, check automatic attributes to be given to
the export file name and select the values, which that file should contain. Via the Add File button, you can
create more History Data tabs, to get several different configured export files from the same measurement
in the same export process.
