Target Coupler 17 3
6.3.1 Taking Basic Measurements
For your convenience, instructions for taking basic coupler measurements are
given here:
1. Enter the Coupler Target or Coupler EarSim screen by pressing [F3] from the
Opening screen and using the [NEXT] or [BACK] keys as necessary.
2. Press [MENU] from the measurement screen to make any necessary selec-
tions. See Section 6.4 for details.
3. Level the sound chamber as described in Section 3.2, if necessary.
4. Set up the aid in the sound chamber as described in Section 3.3.
5. Use [F2] to select a curve number.
You can measure 4 different curves in the FP35. By default, their source levels
are:
Curve 1: 50 dB
Curve 2: 65 dB
Curve 3: 75 dB
Curve 4: 90 dB
6. Use [∧,∨] to adjust the source level to the desired amplitude.
7. Use [F4] to select the source type.
8. Press [START/STOP] to initiate the frequency sweep. If you are using the
NORMAL, SHORT, or LONG selections, the test will stop when the sweep is
complete. The COMP, DIG SPCH, and FAST signals are continuous, making
it necessary to press [START/STOP] again when you want the signal to stop.
9. Use [<, >] to scroll back through the last four real-time measurements if
you used the COMP or DIG SPEECH signals.
10. Repeat steps 5-9 to take another measurement.
6.3.2 Viewing Target Data
You can view the numerical data of your response curves with the DATA/
GRAPH selection in the main local menu of the Target Coupler screen and using
[F2] to select the desired curve. If you want to view the numerical data of the
target curve itself, you must use the TABULATION field in the Advanced Target
Coupler menu. The feature is only available when the USER LEVEL is set to
ADVANCED in the Default Settings menu. See Section 2.3.2 for details.
The tabulation feature will add a table to the right of the Target Coupler graph,
displaying the target in numerical format. Tabulation is only available when the
measurement data is displayed in graphical format. When numerical data for
the measured curve is displayed, there is not enough room for the target tabula-
tion box on the screen.
