AT235 Additional Information

Reflex settings

Select a reflex test in your Protocol settings. By rotating the wheel, the following settings can be selected and
changed. Note that this example shows all currently available reflex stimuli.
A
Auto run. Once enabled for a test auto run will cause this test to be automatically run as part of
the protocol.
B
Level increase. This defines the incremental level of each step during the threshold finding.
Incremental levels from 1 dB to 20 dB can be chosen.
Either Fixed number of reflexes or Auto stop must be chosen. When selecting Fixed number
C
of reflexes, the reflex test will complete the sequence from Start level up to Stop level, also if the
threshold criterion is attained before reaching Stop level. When Auto stop is chosen, AT235 will
detect the reflex threshold according to the threshold criterion and confirm the reflex at the same
intensity.
Then the sequence is stopped. The stimulus level will never exceed the intensity level which is set
as Stop level.
D
Threshold criteria let you set the sensitivity of the pass criteria. Three options are available:
• Very sensitive (0.02ml) which means a "pass" is given for a change in compliance larger than
0.02ml (at all probe tone frequencies)
• Sensitive (0.03ml), which means a "pass" is given for a change in compliance larger than
0.03ml (at all probe tone frequencies)
• Normal (0.05ml), which means a "pass" is given for a change in compliance larger than 0.05ml
(at all probe tone frequencies)
• Robust (0.08ml), which means a "pass" is given for a change in compliance larger than 0.08ml
(at all probe tone frequencies)
