Real-Ear Measurements 151
6.4.6 Using Semi-Auto and Fully-Auto Mode
The Real-ear Insertion Gain and Real-ear SPL screens have basic implementa-
tions of Semi-Automatic and Fully-Automatic test modes. In Semi-Automatic
mode, the analyzer automatically advances to the next measurement curve
when the measurement is stopped. That is, if the user selects REUR 1 and takes
a measurement, the analyzer will automatically advanced the curve selection to
REAR 2. This eliminates the need for the clinician to press [F2] and manually
advance to the next curve. Semi-automatic mode is available in both the Real-
ear Insertion Gain and Real-ear SPL screens.
To activate semi-automatic mode:
1. Enter the Real-ear Insertion Gain or Real-ear SPL screen.
2. Press [MENU] to open the local menu.
3. Select Auto Test under Measurements [∨, ∧]. Pressing [START] will jump to
the beginning of the next section in the local menu.
4. Choose Semi-Auto using [<, >].
5. Press [EXIT] to return to the real-ear measurement screen. The analyzer will
now be in Semi-Automatic mode.
Fully automatic mode automatically measures REAR 2, REAR 3, REAR 4, and
REAR 5 in quick succession. When REUR 1 is selected, after pressing [START]
to perform the unaided measurement, the user must still press [STOP] to stop
the test. This will automatically advance the curve selection to REAR 2, but no
measurement will be taken until the [START] button is pressed again.
Fully-automatic mode is only available in the Real-ear SPL screen. It does not
work in the Real-ear Insertion Gain screen.
To activate fully-automatic mode:
1. Enter the Real-ear SPL screen.
2. Press [MENU] to open the local menu.
3. Select Auto Test under Measurements [∨, ∧]. Pressing [START] will jump to
the beginning of the next section in the local menu.
4. Choose Fully-Auto using [<, >].
5. Press [EXIT] to return to the Real-ear SPL screen. The analyzer will now be
in Fully-Automatic mode.
6.4.7 Testing with a single tone or three frequency average
It is sometimes useful to be able to look at a hearing aid’s response to a single
frequency or to a repeating three-frequency sequence. To measure with one of
