Most common repairs + troubleshooting for the Maico MI 24 Tympanometer at Acme:

1. Leaking: This occurs when the ear tip does not make the auditory canal airtight. The probe's control light turns yellow, and the LCD display shows "LEAKING" under status. This requires the probe's position to be adjusted or a larger ear tip to be used​​.
2. Blocked: Indicates the sealing of the probe opening, leading to a blockage. The control light on the probe will turn yellow, and "BLOCKED" is displayed under the status on the LCD display. This requires checking the probe for blockage by ear wax​​.
3. Cavity calibration out of range: If this error occurs during probe calibration, it suggests the probe or the instrument may be defective. It prompts checking if the probe tip's opening is clean and attempting recalibration. Persistent error messages indicate a need for service​​.
4. High ear canal volume reading due to a perforation in the tympanic membrane: The instrument will measure the entire middle ear space volume, which could indicate a defect with the device's measurement capabilities or an issue with the patient's ear​​.
5. Extremely flaccid tympanic membrane or ossicular chain discontinuity yielding very high peak compliance: This may falsely indicate normal middle ear pressure when in fact there is a mechanical issue with the middle ear system​​.
6. Fixation of the ossicular chain (otosclerosis): Produces a tympanogram with very low compliance despite normal middle ear air pressure, suggesting an issue with the device accurately measuring compliance under specific pathological conditions​​.
7. Middle ear fluid (serous otitis media): Results in a very flat tympanogram with no definite peak and negative air pressure, which could be misinterpreted by the device as a defect or abnormal operation​​.
8. Eustachian tube dysfunction: Shows a normal compliance curve displaced to the negative side of the tympanogram, which might confuse the diagnosis without clear error messages but indicates potential measurement challenges​​.
9. Failure to perform reflex tests on the basis of a high probe tone tympanogram: Indicates a limitation or potential defect in the device's capability to conduct reflex tests under certain conditions, specifically when a high probe tone is used​​.
