4.
Contralateral is available with Versions 2 and 3 only.
Pressure:
226 Hz Probe Tone:
Reflex measures are set automatically to
pressure at peak compliance with an offset of -20 daPa if peak
pressure is negative and +20 daPa if peak pressure is positive.
1000 Hz Probe Tone:
Reflex measures are taken at 0 daPa regardless
of peak pressure.
Reflex Determination:
226 Hz:
Compliance change of 0.05 cm
3
or greater.
1000 Hz
: Compliance change of 0.1 mmho.
Reflex Test Time:
1 to 12 seconds depending upon the number of ipsilateral and/or
contralateral test frequencies selected (4 maximum) and intensity
required.
