adjacent to the button flashes green and continues to flash while Auto Detect is in progress. If a fault
is detected, the flashing light changes to red and an error log is displayed listing the channel/s on
which the test failed.
Alternatively, review the information manually, using the scroll arrows on the right of the Ultrasound
Scope window to select a vector between 0 and 63. The selected vector is displayed in the Vector
# field and its test results are displayed in the Spectrum area.
Check the test results for each vector, as follows:
• Verify that the RMS level displayed in the RMS field is above 84 (in absolute value).
• Verify that the amplitude at frequency 2.5 is within a range of -5 to -20.
• Verify that the amplitude at frequency 5 is below -40.
• Verify that the amplitude at frequency 7.5 is below -60.
Note: If the RMS level is above or below the specified level, reboot the system, perform
calibration and repeat the test.
