Electro-acoustic calibration using an OSCAR™ electro-acoustic ear and your
Tremetrics RA500 Microprocessor Audiometer A
typical test procedure would be as follows: 1. Turn on the power to the audiometer. When the information screen appears, hit the enter key. 2. Count the number of cables that connect the audiometer to the booth and proceed to step 3 accordingly. 3. If there are two cables that connect the audiometer to the booth, locate the patient response switch inside your audiometric booth and disconnect it from the booth jack by pulling it out completely from the wall. Insert the Oscar cable plug into the jack where the patient response switch was previously connected. The Oscar should now be connected inside your booth where the patient response switch was previously connected. Proceed to step 4. If there are three cables connecting the audiometer to the booth, DO NOT disconnect any cables. Simply turn the OSCAR on and proceed to step 4. 4.
Place the earphones onto the Electro Acoustic Ear. 5. Turn on the OSCAR by sliding the power switch from the off to the on position. 6.
Press
the audiometer ENTER KEY. 7.
PRESS THE BLUE NEW
TEST KEY. 8.
PRESS THE BLUE YES KEY. 9. If the baseline for OSCAR has been stored in the audiometer, Press the 0 (ZERO KEY) and then the enter key. Generally, the baseline for OSCAR is set and stored by your calibration contractor during annual exhaustive calibration. If,
however, the new current test is to become the NEW baseline, press the 1 (one)
key and then the enter key. 10.
For the patient name, type the word OSCAR
and then press the enter key.. 11.
Press
the Run Test key. 12. At the end of the test the audiometer will beep and automatically print the results. Press the Store key if you wish to store the result, or press any other key if you do not wish to store the results. 13. Examine the test strip from the audiometer. If this current test is not the baseline, the strip should display the current test, the baseline test and provide a third portion that depicts any differences. Acceptable readings are readings that are +/- 5dB from the baseline results. 14.
Record the results on the daily biological log or staple the results to a plain
sheet of paper and store in the daily biological binder.
All data should compare within ± 5dB of the original baseleine. Click here to view or print the Lipin/Dietz Daily Biological Audiometer Calibration Check sheet.
