7 Use of the program with TSM400, TSM500, T830 & T840
Basic operation of the program:
Start the program and connect the tympanometer to the USB port. The program will start at probe tone 226
Hz, 100 dB calibration level, and the tone output will be turned on.
The available buttons for tympanometer will appear on the screen.

The values in the write fields show the
difference in dB for calibration. On the right
side, you will find the RETSPL values for
each frequency. See section 6. Hearing level
offsets for more information.
The program can be controlled by the mouse, dragging the sliders and clicking the buttons. However, to
make the calibration process more convenient, it can also be controlled by the keyboard.
Changes the frequency.
Move calibration sliders 1 step down, -0.1 dB
Move calibration sliders 1 step up, +0.1 dB
Move calibration sliders 10 step down, -1 dB
Move calibration sliders 10 step up, +1 dB
Change function between air, left, right, and
bone
The program automatically
detects the audiometer type,
and the bone and masking
buttons in the top of the main
screen and will only be
present if the audiometer
supports bone and masking.
By using the keyboard, you
can keep your eyes on the
calibration equipment all the
time, instead of having to
look at the PC monitor to
follow the mouse pointer.
