measured with an MZ coupler and OES correction factors. Curve 1 was measured using
a standard 2-cc coupler.
3.8 Automatic Testing—Loading & Saving Groups
You can use the 7000 Test System to program simple automated or semi-auto-
mated test sequences that will help you test hearing aids more efficiently. Each
test sequence can contain up to 10 different response curves with your choice of
source types, source levels, noise reduction, and other adjustments.
In automatic mode, the analyzer will quickly run through all designated tests
without pausing. In semi-automatic mode, the analyzer will automatically
advance to the next curve and stop. This curve will not be measured until you
start the test, but you are saved the step of using F2 to select the next curve
number.
Tests are programmed into the analyzer using the PROGRAM function that is
used to put the analyzer in Program mode. In this mode, you set up the source
type, source level, noise reduction, and any other adjustments you would like to
make for each curve. You can program any of the available 10 curve slots in the
Coupler screen. See Section 3.8.1 for more details.
