Preparing for testing AccuScreen PRO User Manual
Note:
The hydrogel of the electrodes can dry out. Make sure that used
packages are closed properly. Dried out hydrogel may cause unex-
pectedly high electrode impedance. If this is the case, change the
electrodes.
5.5.2 Fitting the eartip on the probe
1. Select an ear tip that fits the patient's ear canal. You may have
to try out a number of sizes in order to select the appropriate
size.
2. Gently push the eartip onto the probe tip, with the hollow of
the eartip (A) facing away from the probe, until it rests firmly
on the base (B) of the probe. It is much easier to attach and
remove the eartip if you turn it gently. When you do so, make
sure that you hold the probe by the plug and
not by the cable .
Note:
Accurate testing is only guaranteed if you use the eartips pro-
vided.
Note:
The probe can be used for both ears. If you suspect infection in
one ear, exchange the eartip and clean the probe tip, or replace
it with a spare, before you continue testing on the other ear.
WARNING:
Using a probe with an unsuitably sized eartip or applying
excessive force may irritate the ear canal.
Note:
In case of a probe error, make sure that the probe tip channels
are clear (see
Section 12.1, ‘Probe cleaning and maintenance”
on page 81 ) and that the probe is connected. See also Section
11.1.1, ‘Probe test” on page 72 .
