Protective Classification: This system is intended for continuous operation and has a protective
classification of Class 1.
Class 1 Type B
Probe Tone: 226 Hz, ±2%
Sound Pressure Level: 226 Hz: 85.5 dB SPL, ±2.0 dB, measured in a 2.0 cm 3 coupler
Harmonic Distortion: <3%
Admittance (Compliance) Range: 226 Hz: 0.0 to 1.5 cm 3 or 0.0 to 3.0 cm 3
Notes:
1. The range is automatically selected based upon the amplitude of the
compensated tympanogram.
2. The maximum uncompensated (ECV + tympanogram peak) admittance
(compliance) range is 0 to 5.0 cm
3 .
3. ECV/cavity limits for initiating pressurization is 0.2 to 5.0 cm
3
.
Compliance Accuracy: ±0.1 cm 3 or ±5%, whichever is greater.
