Possible solutions:
• Reposition probe tip
• Patient and practitioner must remain still
• Use a different size probe tip
• Increase pressure against the ear
If a leak condition occurs after -100 daPa pressure is reached at 226 Hz, results will remain
on the display. If an identifiable peak is displayed at 226 Hz, you do not have to repeat the
test. If no peak can be identified, repeat the test and try repositioning the tip, using a
different size tip, or increasing the pressure against the ear canal opening.
If a leak condition occurs after -300 daPa pressure is reached at 1000 Hz, the PASS,
REFER, or RETEST results will be displayed.
