Specifications

Welch Allyn TM286 AutoTymp Tympanometric System Specifications

Tympanometry Mode:
- Probe Tone: 226 Hz, +/- 2%.
- Sound Pressure Level: 226 Hz: 85.5 sB SPL, +/- 2.0 dB, measured in a 2.0 cm³ coupler.
- Harmonic Distortion: Less than 3%.
- Admittance (Compliance) Range: 226 Hz: 0.0 to 1.5 cm³ or 0.0 to 3.0³.
- Pressure Range: +200 to -400 daPa.
- Pressure Accuracy: +/-10 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.
Reflex Mode:
- Frequencies: 500, 1000, 2000, and 4000 Hz for ipsilateral stimulation.
- Accuracy: +/- 3 %.
- Total Harmonic Distortion: Less than 5% for outputs less than 110 dB HL and less than 10% at 110 dB HL.
- Rise/Fall Time: 5 to 10msec.
- 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.
Audiometry Mode
- Frequencies: 125, 250, 500, 750, 1000, 1500, 2000, 3000, 4000, 6000, 8000 Hz.
- Accuracy: +/- 2%.
- Total Harmonic Distortion: Less than 2.5% (125 to 3000 Hz measured acoustically at maximum dB HL; 4000 and 6000 Hz measured electrically).
- Audiometric Headset: Pair External earphones Type 51 cushions (60 ohms impedance). Headband force per ANSI S3.6 and IEC 645 (4.5 N +/- 0.5).
- External Headset Earphones: 125 Hz: -10 to 50 dB HL; 500 to 4000 Hz: -10 to 90 dB HL; 6000 Hz: -10 to 85 dB HL; 250 and 8000 Hz: -10 to 70 dB HL.
- Accuracy: 125 to 4000 Hz +/- dB; 6000 and 8000 Hz +/- 5 dB.
- Step Size: 5 dB.
- Signal-to-Noise Ratio: Greater than 70 dB in 1/3 octave; less than -10 dB HL for levels less than 60 dB HL.
- Rise/Fall Time: 20 to 50 msec.
- Continuous: Tone is steady when present bar is depressed.
- Pulsed: Tone is pulsed at 2.5/sec (i.e., 200 msec ON, 200 msec OFF).
- FM (Frequency Modulated): Tone is frequency modulated at a rate of 5 Hz, +/- 5%.
Line Voltage: 100 to 240 VAC (+/- 10%).
Power Consumption: 16 watts maximum while printing. Low-voltage input for desktop power supplies 7 VDC, 5.0 A.
Dimensions: 12.5" [W] x 14.5" [D] x 4.7" [H] (31.8 cm x 36.8 cm x 11.9 cm).
Weight: 5 lb (2.3 kg).
