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:
The number of bars shown indicates the robustness of the seal. The probe should be adjusted in
the ear until two or more bars are shown for Low and High.
Once an adequate seal is detected the following message will be seen and a tympanogram
measurement is made.
