The Models DA118A PPM 360™ Meter is a device that is worn or carried on a person, usually
by means of a belt clip. The PPM 360 Meter collects audio that is watermarked (also known
as “encoding”) with data information using Nielsen Audio’s patented Critical Band Encoding
Technology, and using cellular technology, forwards this information back to Nielsen Audio
data collection servers. The DA118A also determines if the person wearing the PPM 360
Meter, known as a “panelist”, is in his/her home or out of the home using an In-Home
Beacon. The Model DA118A use a headphone adapter accessory when th
e panelist is wearing
hea
dphones to collect this data from MP3 or other audio devices that use headphones.
Charging of the Nielsen Audio Models DA118A PPM 360 Meter is performed by
a Class 2
po
wer unit with USB type connector, or alternatively by use of a cradle system which
interconnects between this same power unit and the meter. The cradle system uses the
same Class 2 power unit with USB type connector; however, the cradle is a nest where the
power from the class 2 power unit USB type connector is transferred to a set of spring pins
which contact with two charge contacts on the side of the Models DA118A meter when the
meter is placed in the cradle nest, thereby charging the meter. The cradle charging system is
also an accessory of the Models DA118A.
