5.4.3 Viewing JIS measurements in the Coupler screen
It is possible to copy JIS response curves to the Coupler screen where they can
be compared to other response curves. To do this:
1. Run the JIS test sequence.
2. Press [F7].
3. Use [
∧
] to select Store Crvs Coup, if necessary.
4. Use [>] to “store” the curves (that is, copy them to the Coupler screen) and
close the pop-up menu. The following is a list of where the curves are cop-
ied in the Coupler screen. Any previous measurements stored in those curve
locations will be overwritten.
• Full-on Gain—CRV 5
• Response—CRV 6
• OSPL90—CRV 6
5. Press [EXIT] and [F1] to enter the Coupler screen and view the JIS response
curves.
5.4.4 Understanding the menu settings
The following menu settings are available in the local menu of the JIS screen.
Measurement Settings
• Noise Red (Tone)—The amount of noise reduction used in the JIS mea-
surements. See Section 2.3.1.2 for more details.
• Battery Meas.—The status of the battery current measurement. Turns it
ON or OFF. (Battery pill required for this measurement.)
• Battery Size—The size of the battery of the hearing aid being tested.
Aid Settings
• Sweep Start Delay—The delay after the first tone is presented in a pure-
tone frequency sweep and before the first measurement is taken.
• Sweep Meas. Delay—The delay between frequencies in a pure-tone fre-
quency sweep.
• Misc. Start Delay—The delay after the first tone is presented and before
the first measurement is taken in the HFA/SPA, reference test gain, equiv-
alent input noise, and harmonic distortion measurements.
• Misc. Meas. Delay—The delay between frequencies in the measurements
mentioned above.
• I/O Start Delay—The delay after the first tone is presented in the I/O
sweep and before the first measurement is taken.
• I/O Meas. Delay—The delay between frequencies in the I/O sweep.
