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 an ES3S audiometer is equipped with the Dual Headset Option, separate
calibration due reminders will occur.
The last calibration date and calibration due dates may be viewed at any time via
the menu sequence
