CALIBRATION
Micro Audiometrics recommends that audiometers be calibrated annually. About
one month before the annual calibration due date, the ES3 will begin displaying a
reminder at power up that the due date is approaching. This reminder will be
cleared once the instrument is calibrated. If the calibration due date passes and
the instrument has not been calibrated, a caution will be displayed regarding
potential test data invalidation.
Note: If the audiometer is equipped with two headsets, separate calibration due
reminders will occur.
The last calibration date and calibration due dates may be viewed at any time via
the menu sequence ⌐S
ETUP ⌐GENERAL ⌐CALIBRATION DATES. Please see the ES3
Calibration Guide for more detailed information regarding headset management
and calibration.
