Quick Guide
Titan ABRIS handheld
PREPARE THE EQUIPMENT
1. Turn on Titan by pressing the R or L button.
2. Choose the test protocol from the list using the up & down arrow keys and then press
Select.
3. To use a different protocol than the one selected, press
Protocol
and then repeat step 2 above.
4. Select the transducer (only if more than one connected to the preamplifier).
5. Select the ear for testing.
TEST ENVIRONMENT
The ideal test environment is a quiet room where lights and other electronic equipment are turned off.
PREPARE THE INFANT
Patient state
The infant should be sleeping or in quiet relaxed state.
Sucking, blinking, crying or movement may affect testing.
Skin preparation
Typically, no skin preparation is required.
If the infant’s skin is oily, the electrode placement sites should be cleaned using
alcohol wipes and/or skin preparation gel.
Use a conductive gel with the electrodes to improve impedances.
Place electrodes
Place surface electrodes using the desired montage (mastoid or nape).
Connect cables
Connect the cables from the PreAmplifier to the respective surface electrodes.
CHECK IMPEDANCE
Impedances are indicated by the green/amber dots on the infant as well as in numerical format on screen.
When the dot is amber, this means the impedance
is poor (> 40kΩ). In this instance, it may be
necessary to clean the skin and replace the
surface electrode.
NB. Testing is possible when impedances are
poor. This may, however, affect test time and
measurements.
