Basic Sound Chamber Tests

In the Coupler screen, you can view measurement curves in dB SPL or dB Gain,

and run them with Composite, Digital Speech, or pure-tone signals. You can dis

play up to 10 curves on the Coupler screen at the same time.

From the Opening screen of the 7000 test system, enter the Coupler screen by

pressing [F1].

The Coupler Multicurve screen can be set as the screen that appears when the

7000 test system is powered or the [RESET] button is pressed. See Section 2.2.1

and 2.2.4 (Other sub-section) for details.
