To Exit Setup Test parameters that may be altered vary according to which test mode
is currently selected: e.g., there is no provision for changing pump speed
in reflex measurements, nor for adjusting the
y -axis in tympanome-
try—only relevant parameters may be changed.
Setup may be exited simply by pressing the Setup pushbutton again.
Setup, More (Version
4.x Only) In Tymp Auto Sweep and ETF-I modes, selecting More changes the sub-
menu choices to: optional use of a measurement pressure level a selected
interval above or below Middle-Ear Pressure (MEP), and Leak Detect on
or off (Version 4.
x ). Press Setup again to return to the function currently
selected.
In Reflex testing, Setup , More enables the addition of Leak Detect on or
off (Version 4. x ).
Here follows an overview of the parameters that may be altered in tym-
panometry, reflex and threshold test modes. To change any test parame-
ter in Setup, press the corresponding
Softkey
repeatedly until the
required choice is shown in the panel above it. Alternatively, hold the
corresponding
Softkey down and turn the Rotary Knob (in either direc-
tion).
5.2.1 TYMPANOMETRY (INCL. ETF-I)
Pump Speed Pump Speed: The settings available are: 50, 100, 200, 400 daPa/sec
and AFAP (as fast as possible).
This parameter is not available in Manual Tymp.
Scaling Y-axis Scaling
(Compliance): The following settings are available: 0.3, 0.6, 0.9, 1.5,
3.0, 4.5 ml or Auto. In Auto, the minimum possible
scaling for the measured curve is automatically
selected.
Averaging Averaging: On/Off (Manual Tymp. only).
