 Start Frequency and Stop Frequency: Select the preferred frequencies using the sliders.
These may for example be set so that they correspond with the hearing aid gain handles
(e.g. if the hearing aid goes up to 8000 Hz there is no reason to measure beyond this
frequency). To avoid low frequency noise you may wish to set the slider to a start frequency
of 200Hz.
 Sweep delays: This is relevant if Continuous measurement is selected for Pure Tone or
Warble Tone. In this case sweep delays (in milliseconds) may be entered between the
individual sweeps (see section 0 for details).
 Measurement time (in seconds): Duration for the measurement can be set using the slider.
This is only relevant for broad band signals. A number of seconds can freely be selected
between 1 and 1200. By default the measurement time is the same for all signals.
 Instructions: This allows for adding picture instructions. If the box is ticked an instruction box
explaining how to perform the measurement will appear each time upon pressing START.
3) Recording Method:
 Resolution (of frequency): Select the preferred resolution in the dropdown. The higher the
resolution the slower the measurement.
4) Colour:
 Select a colour for the Right and Left curve (see section 2.6.2.1 regarding REUR/REUG for
details).
5) Multiple Curves:
 The Multiple curves option, if configured, will run a series of concurrent differing intensity
levels when you press start in the test screen. Set the first level using the Input Level slider
and press Add under Multiple Curves. The level will then appear in the corresponding white
section as the Primary intensity. Select the second level and press Add again. The new level
will then be listed under the first one. If a level is selected by mistake click on it in the white
section and press Remove.
