SAVE THE DATA
Desired pressures were not reached. This happens when the tip
becomes dislodged in the ear canal or if there is a very slight leak
throughout the test. Though the test has been interrupted, partial
results are displayed. A line at 1.4 mmho has been plotted after the
leak condition occurred. Provided that an identifiable peak is present,
the test need not be repeated. If no peak can be identified, follow
instructions for LEAK
(=i=
)
condition.
OPEN
The test has not begun because the total measured admittance (the
sum of + 200 Vea and Ya) exceeds 3.5 mmho. This occurs when:
l the unit is not in an ear.
l the probe is not completely sealed in an ear.
l used on perforated or hypermobile tympanic membrane, an ear
with patent tympanostomy tubes, or an extremely large canal.
Use of a different tip size may alleviate this condition. See
Guidelines for Screening (pg. 32) if condition persists.
