Probe and Accessories Handling Guide
A correct placement of the probe in
the ear canal secures a stable and good
probe fit required for obtaining fast and
reliable test results.
When you have fitted an ear tip on the
probe, gently pull the pinna back and
slightly down and insert the probe in the
ear canal, twisting the probe slightly as
you insert it.
The probe can be inserted with the
probe cable pointing either upwards
or downwards, depending on which
direction fits best. Make sure that the
probe fits well. If available, the probe
cable clip can be used to fixate the probe
cable e.g. on the patient’s clothes. Any
leakage may increase the test duration
because of distortion and excessive noise.
Correct probe placement.
It is important that the probe tip points in
the direction of the tympanic membrane
and not towards the ear canal wall (see
illustration below).
