RECALIBRATION
The U.S. Occupational Safety and Health Administration (OSHA)
recommends that audiometers be recalibrated annually.
Arrangements may be made by returning the AudioScope 3 regis-
tration card or contacting Welch Allyn’s Technical Service
Department or an authorized Welch Allyn Distributor. A moderate
fee is charged for recalibration.
In addition, a daily biological check may be performed. This is
accomplished by a person with known normal hearing who listens
to the tones for intensity and quality.
