Welch Allyn AutoTymp TM262

• Three-in-one instrument with built-in display and printer saves space and the expense of buying separate units.
• Provides an easy tympanometric seal via a lightweight, hand-held probe.
• LEDs give step-by-step accounts of test status, indicating proper ear seal, test mode, and test completion.
• Test-parameter flexibility lets user decide how to run tests.
• Convenient memory capacity stores up to eight test results instantly.
• Printout flexibility allows the user to print individual test results or a complete battery, eliminating the need for note taking.
• Has a built-in calibration check and optional audiometry and RS-232 port to download patient data into PCs.

Tympanometry/Reflex Modes
Probe Tone: 226 Hz, ± 3%
Sound Pressure Level: 85.5 dB SPL, ± 2.0 dB, measured in a 2.0 cm3 coupler
Harmonic Distortion: <5%
Admittance (Compliance) Range: 0 to 1.5 cm3, 0 to 3.0 cm3

Note:
1. The range is automatically selected based upon the amplitude of the compensated (tymp only) tympanogram.
2. The maximum uncompensated (ECV + tympanogram peak) admittance (compliance) range is 0 to 5.0 cm3.
3. ECV/cavity limits for initiating pressurization is 0.2 to 6.0 cm3. Compliance Accuracy: ± 0.1 cm3 or ± 5%, whichever is greaterr

Pneumatic System
Pressure Range: +200 to –400 daPa

Note:
1. 1 daPa = 1.02 mm H20
2. Pressure sweeps to at least –100 daPa. To save test time, pressure sweep stops once tympanogram returns to baseline after –100 daPa.
3. Full pressure sweep for 6 cm3 from sea level to 7000 ft. altitude with no leak.
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
Tympanometric Test Time: approximately one second

Note:
High compliance tympanograms will take somewhat longer Gradient: Tympanogram pressure width at 50% of peak compliance.

Acoustic Reflex Stimuli
Frequencies: 500, 1000, 2000, and 4000 Hz
Accuracy: ±3%
Total Harmonic Distortion: <5%
Rise/Fall Time: 5 to 10 msec
Output Levels:
IPSI: 500 and 4000 Hz:80, 90, 100 dB HL
1000 and 2000 Hz: 85, 95, 105 dB HL

Note:
1. Ipsi stimuli are time multiplexed with probe tone (106 msec ON, 53 msec OFF).
2. 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.

Pressure: Automatically set to pressure at peak compliance with an offset of –20 daPa.
Reflex Determination: Compliance change of 0.05 cm3 or greater.
Reflex Test Time: 1 to 12 seconds depending upon the number of ipsi test frequencies selected (four maximum) and intensity required.
Probe LED Indicators:
Steady yellow: occlusion
Blinking green: ready to start testing
Steady green: test in progress
Steady orange: leak

Warranty
1-year warranty extendable to 3 years with annual calibration.
