The MA 53 can be connected for data transfer to a PC.
Caution: The computer you are using must meet electrical safety
requirements, such as IEC 601-1 or UL. This is to avoid electrical shock
of either the patient or you.
All test results are online transferred to the PC and stored in the database.
In pure tone audiometry initially all
measured data is transferred as hearing
threshold data. You can see the letters HL
meaning threshold measurement in the
upper middle of the LCD-display
(see
picture 45).
To test the uncomfortable level (UCL) press the receiver selector button
or
longer than 2 seconds and the LCD-display
in the upper row changes
from HL to UL. All measured data is now transferred as UCL data.
To test the most comfortable level (MCL) press the receiver selector button
or
longer than 2 seconds and the LCD-display
in the upper row changes
from UL to ML. All measured data is now transferred as MCL data.
In speech audiometry initially all measured
data is transferred as multisyllable test data.
You can see the indication MS in the upper
middle of the LCD-display
(see picture
46).
To test with single syllables press the
receiver selector button
or
longer than
2 seconds and the LCD-display
in the upper row changes from MS to SS.
All measured data is now transferred as single syllable test data.
To test the uncomfortable level (UCL) for speech press the receiver selector
button
or
longer than 2 seconds and the LCD-display
in the upper row
changes from SS to UL. All measured data is now transferred as UCL speech
data.
