INTRODUCTION
Thank you for purchasing a Welch Allyn MicroTymp 4, a hand-held, portable tympanometer that
will give many years of reliable service if treated with care. The instrument performs two types
of measurement:
Tympanometry is used to measure the admittance of the tympanic membrane and middle ear
at a fixed frequency over a range of pressures.
Acoustic Reflex tests are used to measure stapedial reflexes. The MicroTymp 4 measures
ipsilateral reflexes and, when selected, reflex measurement is automatically carried out after a
tympanogram is taken.
Features
Automatic measurement of ear canal volume, tympanic admittance peak, placement of
the peak and the gradient
Automatic detection of stapedial reflexes
Up to 32, dual-ear patient tests can be stored in non-volatile memory
Configurable settings for user preferences, held in non-volatile memory
Printout of data to a printer
English, German, French, Spanish, Portuguese or Italian operating language (selectable by
the user)
INDICATION FOR USE
The Welch Allyn MicroTymp 4 is intended to be used for the measurement of acoustic
impedance/admittance within the human external ear canal. These measures are useful in the
evaluation, identification, documentation and diagnosis of ear disorders. The device is intended
to be used on patients of any age.
INTENDED USE
The Welch Allyn MicroTymp 4 is an auditory impedance tester intended to detect possible
otologic disorders associated with the functioning of the middle ear. It is intended to be used in
a hospital, clinic or other healthcare facility with a suitable quiet testing environment such as a
private exam room.
DIR 80024157 Ver C Page 3
CONTRAINDICATIONS
Ear canal examination with an illuminated otoscope is an essential prerequisite to successful
middle-ear testing. Make sure that the canal is free of any obstruction. If the canal is completely
plugged at the entrance or if fluid is running from the ear canal, tympanometry should not be
attempted until the condition is cleared. Testing should not be performed on patients with
conditions listed below without a medical doctorâs approval.
Recent stapedectomy or other middle ear surgery
Discharging ear
Acute external auditory canal trauma
Discomfort (e.g. severe otitis externa)
Presence of tinnitus, hyperacusis or other sensitivity to loud sounds may contraindicate testing when high intensity stimuli are used
DESCRIPTION AND OPERATING PRINCIPLES
The Welch Allyn MicroTymp 4 is clinical aural acoustic impedance/admittance instrument (Type
2). The main components of the instrument consist of a hand held unit with an LCD and a probe
assembly and a cradle. A printer, eartips and test cavity are included with the system.
The probe contains one microphone, two receivers and an air channel. One of the receivers is
used for probe tone signal. The second receiver is used for the acoustic reflex stimulus signal.
The microphone measures the response. The air channel is connected to the pump system which
makes it possible to supply the eardrum with air pressure
ADMITTANCE MEASUREMENT
The MicroTymp 4 measures the admittance of the tympanic membrane and middle ear by playing
a continuous 226Hz tone into the ear canal at a level calibrated to give 85dB SPL into a 2ml cavity.
The sound level this produces in the ear canal is measured using a microphone and the
admittance calculated from the result. In line with normal audiometric practice admittance is
displayed as an equivalent volume of air in ml.
TYMPANOGRAM
To record the tympanogram the admittance is measured while the air pressure in the ear canal
is varied from +200daPa to -400daPa by means of a small pump. The admittance peaks when the
air pressure is the same on both sides of the tympanic membrane. The changing admittance with
pressure is displayed as a graph.
ACOUSTIC REFLEX MEASUREMENT
Using the same principle, it is also possible to establish whether an acoustic reflex is present. In
this case, the 226Hz tone is used to measure the admittance of the ear, while a short tone at a
DIR 80024157 Ver C Page 4
different frequency is presented (the reflex stimulus). The sound pressure level (SPL) of this
stimulus is increased in steps until the middle ear muscles respond causing the tympanic
membrane to become stiffer, or a preset maximum SPL is reached. When the change in
admittance exceeds a predetermined threshold, this constitutes a reflex and the change in
admittance at that level when the stimulus is applied is displayed as a plot against time.
The acoustic reflex is measured at the static ear canal pressure that produces the maximum
membrane admittance, so reflex measurements are taken after the tympanogram is measured
when the peak admittance pressure has been established.
The MicroTymp 4 can measure an acoustic reflex at any combination of 500Hz, 1000Hz, 2000Hz
and 4000Hz. The maximum level for the reflex stimulus may be preset, along with the step size
in dB between the three preceding lower levels of stimulus.
DIR 80024157 Ver C Page 5
INSTALLATION
EXTERNAL INSPECTION
Although this Welch Allyn MicroTymp 4 was carefully tested, inspected, and packed for shipping,
it is good practice after receiving the instrument to immediately examine the outside of the
container for any signs of damage. Notify the carrier if any damage is observed.
UNPACKING
Please retain the carton and packaging as the tympanometer will need calibrating on an annual
basis and should be returned to the distributor or Welch Allyn in its original shipping carton.
Please check the contents of the shipping carton against the delivery note to make sure that all
items ordered have been included. If anything is missing, please contact the distributor who
supplied the tympanometer or Welch Allyn.

INITIAL SET UP
Place the cradle on a stable counter or table where it will be used. The location should be near a
properly grounded wall outlet. When placing the handset in the cradle make sure that the
connectors on the handset and cradle align.
POWER SUPPLY
The Welch Allyn MicroTymp 4 tympanometer is designed for continuous operation and is
powered by a rechargeable Nickel-Metal Hydride (NiMH) battery-pack which is fitted in the
instrument. If the instrument is placed onto its cradle the battery within it will be charged.
The mains adapter is supplied and specified as part of the equipment. Connect the output lead
from the adapter into the power socket on the rear of the instrument cradle. Switch on the mains
supply - the indicator on the adapter will illuminate green. The mains adapter is the mains
disconnect device and therefore the tympanometer should be positioned such that easy access
to the mains adapter is possible.
The output from the mains adapter is fitted with electronic circuit protection. In case of overload
the adapter will shut down and the indicator will be off. When the fault is cleared the adapter
will operate as normal.
The input to the mains adapter is protected with a non-replaceable fuse. If this fails, the adapter
will not operate and will need to be replaced. If a replacement mains adapter is required, please
contact your Welch Allyn distributor.

DATA COLLECTION
WARNING
Ensure that the appropriate settings have been made before carrying out a test.
See the information below and the CONFIGURATION options in the previous
section.
PRIOR TO TESTING AND AMBIENT CONDITIONS
A qualified health care professional should perform a thorough otoscopic examination to
establish that the condition of the ear is suitable for the test options selected and that no
contraindications are present. The latter would include obstruction of the external ear canal due
to excessive wax and/or hairs, both of which would need to be removed.
Tympanometric and reflex testing should always be performed in a quiet room or in an acoustic
booth.
EAR TIPS
These must be selected and fitted by a practitioner qualified to perform tympanometric tests.
WARNING
The probe tip must be fitted with a new ear tip before it is presented to a patientâs
ear canal. The ear tip must be fitted completely to the probe tip and must not
occlude any of the four holes in the probe tip. The ear tip size is chosen to suit the
patientâs ear and provide a comfortable pressure seal.
DIR 80024157 Ver C Page 17
PERFORMING A TEST
Testing should be conducted in a quiet environment such as a private examination room. No
specific action is required by the patient during the automatic test. However, the patient must
be advised to remain still and avoid speaking or swallowing while the probe is applied to the ear.
A typical tympanogram measurement and reflex test is carried out as follows.

EAR SEAL CHECK
The type of ear seal check employed at the start of a test may be set in the CONFIGURATION
menu. The default STANDARD option is adequate for most circumstances, and this checks that
an adequate pressure can be created in the ear canal before starting the test.
However, if difficulty is experienced in using the eartips to create a seal the alternative EXTENDED
option may be helpful. This checks that a range of pressures will be available before starting a
test by means of a visual indication of the quality of the seal:
TESTING LEFT EAR

DIR 80024157 Ver C Page 20
Taking a tympanogram takes about 3 seconds. It is important not to move the probe and to ask
the patient to remain very still during the test.
When the tympanogram is complete the instrument will perform the reflex test(s), if selected.
By default, this test is only performed if a peak is found in the tympanogram. This and other
reflex test options may be changed in the CONFIGURATION menu.
Before starting the reflex test the ear canal pressure will be set to the value that gave the peak
admittance during the tympanogram test. The instrument will then step through the tone
frequencies and levels set in the CONFIGURATION menu searching for a reflex response:

TEST CAVITY READINGS AT ELEVATIONS GREATER THAN 1,000FT ABOVE SEA LEVEL
The instrument is a pressure sensitive device that makes measurements relative to ambient air
pressure. Changes in air pressure due to weather or elevation will affect the ECV readout of the
instrument. Slight weather related barometric pressure changes will usually yield volume
readouts with ± 0.1 ml of the expected cavity value, but barometric pressure changes due to
elevation can be more significant. These changes in pressure do not affect the accuracy of the
compliance measurement system in any way. However, it will affect the ECV and Test Cavity
values.
If the MicroTymp 4 is being used at an elevation greater than 1,000 ft, when new, and after
each recalibration, perform a Daily Check on all 4 test cavity volumes (0.2ml, 0.5ml, 2ml & 5ml).
Record the displayed values for each cavity and use these values are ânormalâ when
performing Daily Checks each day thereafter.

EARTIP AND PROBE
WARNING
Handle the probe and accessories with care. Do not allow moisture, condensation,
fluids or debris to enter the probe.
DIR 80024157 Ver C Page 32
Ear tips should be replaced after a single use.
The probe tip and its associated sealing washer are disposable devices. The probe tip should be
checked before each ear insertion to ensure it is undamaged and that none of the tubes through
it are blocked. It should be replaced if necessary.
The small holes through the probe tip must be kept clear. If these become blocked a warning
message will be displayed. The tip must be removed and cleaned or replaced.
To remove the tip, unscrew the nose cone and pull the tip off the probe boss. A small seal will
be found in the base of the probe tip. This should be examined and replaced if it is damaged. Do
not remove the nut securing the boss to the body of the instrument.
CAUTION
The sealing washer should be replaced when the probe tip is replaced if it shows
signs of wear, or if a pressure leak is suspected. When replacing the probe tip,
ensure that the seal is correctly located with the flat side aligned with the flat side
within the base of the probe tip. Push the probe tip over the boss and replace the nose cone.
Make sure that the nose cone is screwed home firmly but do not over-tighten. Do not use any
tools to tighten the nose cone.
After replacing the tip, a Daily Check should be carried out.

APPENDIX - EMC GUIDANCE & MANUFACTURERâS DECLARATION
Portable and Mobile RF communications equipment can affect the Welch Allyn MicroTymp 4.
Install and operate the Welch Allyn MicroTymp 4 according to the EMC information presented in
this appendix and in EMC Tables available at www.welchallyn.com/emc-mt4.
The Welch Allyn MicroTymp 4 has been tested for EMC emissions and immunity as a standalone
instrument. Do not use the device adjacent to or stacked with other electronic equipment. If
adjacent or stacked use is necessary, the user should verify normal operation in the configuration.
Portable RF communications equipment (including peripherals such as antenna cables and
external antennas) should be used no closer than 30 cm (12 inches) to any part of the MicroTymp
4, including cables specified by the manufacturer. Otherwise, degradation of the performance of
this equipment could result.
The use of accessories, transducers and cables other than those specified, with the exception of
servicing parts sold by Welch Allyn as replacement parts for internal components, may result in
increased EMISSIONS or decreased IMMUNITY of the device. Anyone connecting additional
equipment is responsible for making sure the system complies with the IEC 60601-1-2 standard.
ELECTROMAGNETIC COMPATIBILITY
Although the instrument fulfils the relevant EMC requirements precautions should be taken to
avoid unnecessary exposure to electromagnetic fields, e.g. from mobile phones, etc. If the device
is used adjacent to other equipment it must be observed that no mutual disturbance appears.

APPENDIX - USE WITH NON-MEDICAL ELECTRICAL EQUIPMENT
Any person who connects external equipment to signal input, signal output or other connectors
has created a medical electrical system and is therefore responsible for the system complying
with the requirements of clause 16 of IEC 60601-1(General requirements for basic safety and
essential performance).
If connections are made to standard equipment such as printers and computers, special
precautions must be taken in order to maintain medical safety. The following notes are provided
for guidance in making such connections to ensure that the general requirements of clause 16 of
IEC 60601- are met.
The following signal inputs and outputs on the Welch Allyn MicroTymp 4 tympanometer are
electrically isolated to the requirements of IEC 60601-1:
Socket Label Socket Type Typical Connection
USB USB connector
Type B
Computer
RJ6 socket Supplied printer
These measures are incorporated to reduce any potential hazard associated with the use of
mains-powered equipment connecting to these interfaces.
External equipment intended for connection to signal input, signal output or other connectors,
shall comply with the relevant IEC or international standards (e.g. IEC 60950, CISPR 22 & CISPR
24 for IT equipment, and the IEC 60601 series for medical electrical equipment).
Equipment not complying with IEC 60601 shall be kept outside the patient environment, as
defined in IEC 60601-1:(at least 1.5m from the patient).
The operator must not touch the connected equipment and the patient at the same time as this
would result in an unacceptable hazard.
Refer to Welch Allyn at the address given on the front of this user manual if advice is required
regarding the use of peripheral equipment.
