• Align MicGain Pot Calibrates the microphone gain pot as part of the compliance sub-
system alignment of the handle.
• Compliance Subsystem Calibrates the compliance subsystem components (speaker
and admittance gain pots) of the handle.
• Motor Sweep Rate Calibrates the motor subsystem components of the handle.
• Generate Checksum Updates the I2E2PROM checksum. This is necessary after
performing any of the above calibrations. Saves the I E PROM values to the PRM\
directory.
• Tymp Noise Test Runs full Tymp sweeps on different size cavities. Compliance noise
is tested to ensure flat Tymps, and the Vea is checked to match the cavity.
Individual Tests Menu
• Motor Test Commands This menu item leads to a new menu which provides com-
mands to test the motor speed of different size cavities.
• Volume Test This menu item checks the handle can correctly determine the size of
different cavities.
• THD This menu item checks total harmonic distortion of the speaker in the handle.
• Leak Test This menu item checks the leak rate of different pressures in the handle.
• Button Test This menu item checks the handle can correctly read button presses.
• LCD Test This menu item checks the handle can correctly display different patterns
and all pixels on the display are working correctly.
Handle Pressure Menu
• Pressure Up Sends a ‘pressure up’ command to the handle.
• Pressure Down Sends a ‘pressure down’ command to the handle and sums the pres-
sure sweep rate table and displays the total time needed for the pressure down
sweep.
• Set Cavity Size Reads the set cavity size from the handle and prompts the user to
change it. Values from 0.2 to 2.5 are the only accepted response. Escape is not
valid.
• Set Pressure to Handle The system requests the user place the pressure tube on the
handle and then requests a pressure value. The valves in the handle and on the
pressure system are closed and the syringe creates the requested pressure. Pres-
sure range is +220daPa to -420 daPa.
• Read Pressure Sends a ‘read pressure transducer’ command to the handle.
• Close Valve Sends a ‘close valve’ command to the handle.
• Auto Zero Sends an ‘open valve’ and re-load pressure pots command to the handle.
Motor Test Menu
• Set Cavity Size Reads the set cavity size from the handle and prompts the user to
change it. Values from 0.2 to 2.5 are the only accepted response. Escape is not
valid.
• Pressure Sweep Sends a ‘pressure up’ command to the handle, then sends a ‘pres-
sure down’ command to the handle and sums the pressure sweep rate table and
displays the total time needed for the pressure down sweep.
• Auto Zero Sends an ‘open valve’ and re-load pressure pots command to the handle.
Handle Speaker Menu
• Speaker On Sends a ‘speaker on’ command to the handle.
