1.1 FEATURES OF THE ZODIAC 901

With the ZODIAC 901 Middle-Ear Analyzer, Madsen Electronics have
produced a precision impedance measuring instrument which offers the
busy audiologist an unprecedented level of automation, timesaving and
versatility. The Limited Version of the ZODIAC 901 is described in an
Addendum located at the back of this manual.
·
The unique multilingual Liquid Crystal Display (LCD) reduces the re-
quired measurement data instantly to graphical, analog and concise
numerical forms. The large, clear presentation of the data from each
test has been optimized for rapid diagnosis of patient condition.
·
All function selection and pre-setting of parameters are controlled by a
combination of single-function pushbuttons, plus softkeys. The five
softkeys are used together with multi-choice menus displayed on the
LCD. All functions are driven by the software built into the instrument.
Thanks to this style of user interface, using the ZODIAC 901 can be
learnt quickly and easily. This interface eliminates drudgery from the
tasks of calibration and pre-test setting-up, and allows the instrument
to be configured for a very wide variety of tests.
·
Tympanometry and reflex testing may be performed with pressure
and compliance indicated in real time as a graphic Cartesian display or
on analog meters, if preferred (see the display in Fig.1.1).
·
The ZODIAC 901 is an intelligent instrument that can be taught which
tests to perform. Five Madsen Electronics Preset Tests plus the capabil-
ity for four user-programmable test routines are built in, for optimal
operating efficiency. The ZODIAC 901 may also be operated entirely
manually or programmed for the user's own combination of manual
and automatic operation. User-programmable tests enable the user to
select the default parameters of a particular test. The user can also select
a combination of tests to form a battery of preset tests.
·
Intelligence in the ZODIAC 901 is not confined to its memory. If a
measurement is interrupted by an air leak or acoustic interference, the
instrument not only erases the data for the aborted measurement, but
also keeps on re-trying the measurement from the beginning until it
completes it without interruption or until the operator intervenes.
·
The ZODICON™ (Madsen Electronics Zodiac Configuration) pro-
gram enables your Madsen Electronics distributor to configure your
ZODIAC 901 to suit your own particular needs, thus customizing the
instrument into your "personal middle-ear analyzer".
·
User-programmable test routines and custom configuration changes
made using ZODICON™ are stored in non-volatile memory, and are
