FONIX® 7000 - Frye Electronics

Basic Sound Chamber Tests 95
If there is a sequence of tests that you would like to perform frequently, you can
save it into the 7000 Test System’s permanent memory using the SAVE GROUP
function. Three groups of up to 10 curves can be saved into SAVE GROUP 1, 2,
and 3, respectively. The settings for both ears are saved when SAVE GROUP is
used, so it is possible to program one set of settings for the left ear and other set
from the right ear.
When you want to manually load a group that has previously been saved, you
use the LOAD GROUP function. It is also possible to have the 7000 analyzer
automatically load a saved group and put itself in Fully-Auto or Semi-Auto
mode when the analyzer is first turned on or the [RESET] button is used. This
is described in Section 3.8.2. When the "Factory" group is loaded, the factory
default settings are loaded.
3.8.1 Setting up a test sequence
The first step in running your custom automated test sequence is deciding on
the source types and levels of the frequency response curves. When finished,
these selections can be stored into the analyzer’s permanent memory.
1. Use [F4] to delete ALL CURVES & SETTINGS in the Coupler screen. (Press
[F4]. Use [∨, ∧] to select ALL CURVES & SETTINGS. Use [>] to complete the
selection and close the pop-up menu.)
2. Use [F6] to select PROGRAM. This will open a pop-up window with helpful
programming instructions.
3. Use [F1] to select the ear.
4. Use [F2] to select the curve number.
5. Use [F5] to select the desired source type.
6. Use [∨, ∧] to select the desired source level.
7. Press [MENU] and use the arrow keys to change other menu settings, if
desired. Press [EXIT] to return to the coupler screen.
8. Save and advance to the next curve. This can be done two ways:
• Press [START] if you want the analyzer to be programmed to automatically
advance to the next curve and start measuring it.
• Press [STOP] if you want the analyzer to be programmed to advance to
the next curve, but then pause and wait for user intervention before taking
the next measurement. Use this if you want to make an adjustment
to the aid before taking the next measurement. A horizontal line will be
drawn across the Curve Characteristics box when a pause is inserted in
this fashion.
9. Repeat steps 5-8 to select the desired source type and level for all the curves
that you want to measure in the automated test sequence.
