Probe Check (Beginning a Test)
To obtain a seal and measure emissions, gently insert the eartip
into the patient’s ear canal. It should fit snugly and comfortably.
The best test results are obtained when an eartip is inserted
deeply into the ear canal instead of flush with the ear canal. To
begin a test, insert the probe into the ear and select either the
LEFT or RIGHT
arrow key to indicate which ear will be
tested.
After the test ear is selected, the Probe Check screen will be
shown. This Display shows a horizontal bar graph representing
the ear canal volume and at the same time the fitting of the
probe. When the bars are in the orange to the left (Display 3)
this represents a very large ear canal volume or indicates that
the probe is not inserted into the ear or placed properly.
When the bars are all the way to the right (Display 4), this
represents the volume is too small for the test to begin or
indicates that the probe tip is blocked. Reinsertion and/or
inspection of the probe tip is necessary.
When the probe check is anywhere in the green area
(Display 5), the ear canal volume is in the target area for testing
to begin. The test will begin automatically if the probe fit is
stable.
Appropriate adjustment of the probe/eartip position and eartip
size selection should be made until the indicator falls within the
green area and remains stable. If the test will not progress past
the Probe Check phase, change the probe tube, check that the
probe connector is fully seated in the socket and try again.
NOTE: Do not remove or insert the probe from the probe
connector unless the device is off.
When a seal is obtained, the unit will automatically begin
testing (AutoStart) and the yellow ‘TEST’ LED will illuminate
throughout the test.
