FONIX 7000 Hearing Aid Analyzer
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. When you want to load a group that has previously been
saved, you use the LOAD GROUP function. See Section 3.8.2.
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 select the desired noise reduction,
output transducer, and composite type, 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 automati-
cally 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 tak-
ing 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.
10. Press [STOP] after you have set up the last curve that you want to run in the
test sequence. For instance, if you want to run only 4 curves, press [STOP]
after setting up CRV 4. This will make the analyzer pause after the four mea-
surements – the remaining 6 available curves will not be run.
11. Use [F6] to SAVE GROUP 1, 2, or 3, if desired. This will permanently save
the automated sequence.
