Abr Disposables & Accessories - Interacoustics Eclipse Additional Information

Eclipse Additional Information
Q: Does the screen show the absolute latency or is there a correction for Inserts Phones already
factor in the display?
A: Corrections are made for Insert Phones (Eartone ABR and IP30), so you can make a direct readout of
the true latency.
Q: During data acquisition is it possible to mark the waves?
A: Yes, it is possible to mark a peak from both the Record tab and Edit tab during measurement. The
curve you want to mark must be selected.
Q: When I enter latency template data, the instrument sometimes alter them slightly. Why?
A: The instrument works with an accuracy of two digits with the latency template data, this equals one
hundredth of a millisecond. If you enter a norm value with three digits, the number will be rounded to
match the two digit design.

Q: Can I reuse the supplied disposable electrodes?
A: No, they are intended for single use only.
Reusable electrodes are available from Interacoustics. When using reusable electrodes you must be
sure that they are free of old gel – so cleaning of reusable electrode is important.
Q: Can I use the EAR5A, EAR3A or IP30 (10 Ohms) insert earphones?
A: No! The system is calibrated for EARtone ABR and IP30 (50 Ohms) insert phones. There are differ-
ences in the impedances and the shielding of other insert earphones.
Note Neither EARTONE 3A 10 Ohms, IP30 10 Ohms, nor 5A can be used for ABR!
At 50 Ohm a minor current must be drawn in order to stimulate with high intensities - less current - less
noise. EARTONE 3A 10 Ohm is only for audiometers. At 10 Ohm a higher current must be drawn in
order to stimulate with high intensities - more current - more noise.
Q: Why do I get two different set of electrode cables? Can I use alternatives?
A: The button connector type cable set is used for electrodes with button connectors, like the ones sup-
plied.
The cable set with plug connectors is used for alternative electrodes holding this type of connector.
Other cables and electrodes are available.
Q: Do I have to use Insert phones?
A: No. You may also use the shielded TDH39 or DD45 .They are not an included accessory, but may be
ordered separately. It is possible to use and shift between the transducers but the test protocol must
be adjusted to match the selected transducer. This is done from the setup, when using headphones
the protocol must indicate so (appearing in the right of the test screen).
Q: Can I use bone conductor?
A: Yes, it is an optional accessory and can be calibrated independently from the phones.
