Operating Temperature | 59° F to 104° F (15° C to 40° C) |
Warm-up Time | 10 minutes for instruments stored at room temperature |
Storage/Shipping | -30° F to 149° F (-34° C to 65° C) |
Ambient Pressure | 98 kPa to 104 kPa |
Humidity | 15% to 95% |
Warranty | One Year Warranty |
Probe Tone | 226 Hz, ±2% |
Sound Pressure Level | 226 Hz: 85.5 dB SPL, ±2.0 dB, measured in a 2.0 cm3 coupler |
Harmonic Distortion | < 3% |
Admittance (Compliance) | Range: 226 Hz: 0.0 to 1.5 cm3 or 0.0 to 3.0 cm3 |
Note:
- The range is automatically selected based upon the amplitude of the compensated tympanogram.
- The maximum uncompensated (ECV + tympanogram peak) admittance (compliance) range is 0 to 5.0 cm3.
- ECV/cavity limits for initiating pressurization is 0.2 to 5.0 cm3. Compliance Accuracy: ±0.1 cm 3 or ±5%, whichever is greater.
Pressure Range | +200 to -400 daPa |
Pressure Accuracy | ±10 daPa or ±15%, whichever is greater |
Rate of Sweep | 600 daPa/sec except near tympanogram peak where sweep rate slows to 200 daPa/sec to provide better definition of peak compliance. |
Direction of Sweep | Positive to negative |
Tympanogram Test Time | Approximately 1 second |
Gradient | Measurement of the tympanogram width taken at 50% of peak compliance. |
Note:
- 1 daPa = 1.02 mm H20
- The pressure sweeps to at least -100 daPa. To save test time, pressure sweep stops when tympanogram returns to baseline after -100 daPa.
- Full pressure sweep for 5 cm3 from sea level to 7000 ft. altitude with no leak.
- High compliance tympanograms (test time) will take somewhat longer.
Frequencies | 500, 1000, 2000, and 4000 Hz for ipsilateral stimulation |
Accuracy | ±3% |
Total Harmonic Distortion | < 5% for outputs less than 110 dB HL and <10% at 110 dB HL |
Rise/Fall Time | 5 to 10 msec |
Transducers | |
Ipsilateral | Probe Assembly |
Output Levels | |
Ipsilateral | 500 and 4000 Hz: 80, 90,100 dB HL 1000 and 2000 Hz: 85, 95, 105 dB HL |
Pressure | 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. |
Reflex Determination | Compliance change of 0.05 cm3 or greater |
Reflex Test Time | 1 to 12 seconds depending upon the number of ipsilateral test frequencies selected (4 maximum) and intensity required. |
Note:
- Ipsilateral stimuli are time multiplexed with probe tone (93 ms ON, 66 ms OFF).
- Stimuli are presented at lowest level first. If there is no response, the intensity is increased by 10 dB until a response is detected or the maximum dB HL is reached.
