Screening tympanometer
Compliance peak level (in ml). Pressure of same; Gradient (in daPa);
Ear Canal Volume (ECV) @ 200 daPa.
226Hz +/-2%; 85dB SPL +/-2dB over range 0.2ml to 5 ml.
+200daPa to -400 daPa +/-10daPa or +/-10% (whichever is larger) over
range.
0.2ml to 5ml +/-0.1ml or +/-5% (whichever is larger) over entire range.
Typically 200-300daPa/sec; dependant on ear&cavity volume.

Frequency +/-2%, configurable over range 70dB to 100dB HL (4kHz
restricted to 95dBHL) +/-2dB, referenced to 2ml calibration volume;
Compensates for measured ear volume.
0.01ml to 0.5ml +/-0.01ml configurable in 0.01ml steps.
Four: 100dB with 5dB or 10dB steps;
95dB, 90dB or 85dB with 5dB steps.
Reflex pass/fail at each level tested;
Maximum amplitude of each reflex (seen on printed report and PC report);
Pressure at which reflex was performed.
Pressure at Tympanogram peak, or 0daPa (Always and Prompt Before
