The Modes are: Main Menu, Identification, Daily Calibration, Tymp., Re-
flex, Threshold, User Test Menu, Program Mode, Real Time Clock Setup.
The Activities are: Manual, Sweep, Eustachian Tube Function (ETF-I,
ETF-P), Screening, Decay, Reflex, Fast Screening (FastSCR), Air Conduc-
tion (AirCond).
The Ear is identified as Left or Right, and, in tests where it is relevant,
additionally as CONTRA or IPSI. In tests which make use of an Ear-
phone , this will also be identified if it is connected and Contra is selected,
e.g.: “TDH39”. If Contra is selected and either an insert phone or noth-
ing is plugged in, it will indicated “insert”.
Pump capacity In all tests where the ear canal may be pressurized or depressurized via
the probe by the use of the ZODIAC 901’s built-in pump, a horizontal
scale appears at the top of the display during and immediately after
changes in the static pressure. The purpose of this is to show graphically
how much of the pump’s capacity is required at any instant.
Volume In all tympanometric tests, the Volume (Vol.) of the ear canal is meas-
ured, computed and shown continuously in milliliters (ml) in one corner
of the main sector of the display.
3.3 START-UP
ATTENTION! WARNING!
To avoid damage to the probe’s electronics, NEVER connect or
disconnect the probe while the instrument is powered on!
Connect Headset! 1. Connect the headset via its cable to the rear panel.
Connect AC Cable
2.
Plug the AC cable into the power inlet on the rear panel and then
connect the analyzer to a power source.
Power-On 3. Switch on the ZODIAC 901 by depressing the power switch (located on
the left of the rear panel).
Software Version 4. The power LED illuminates and the screen displays “Memory test” for a
couple of seconds, and then which version of the software is installed
and the date and time of calibration while the instrument runs an
automatic self-test. The lowest line of the display indicates the status of
the test and error messages, if any.
Automatic Self-Test 5. The power-up process takes about a minute, during which time the
pump is run (audible click and hum), probe data is loaded, and the
system memory and the calibration memory are checked. In addition,
analog and electrical circuits are checked and optimized.
