To set auto alert parameters
1 Select either the DICOM LUM test or the CX/EX White Level test or
select both.
For the DICOM LUM test, check the selection box. Then enter a
value for Maximum allowed. The DICOM LUM test is classified a
failure if it produces a value greater than the maximum allowed.
Enter a value ranging from 0 (zero) to 2 (default=1.00). A value of
0 (zero) indicates perfect conformance with the DICOM Grayscale
Standard Display Function. The DICOM LUM Test assesses the
standard deviation of JNDs (Just Noticeable Differences) per
digital interval.
EXAMPLE: Maximum allowed: 1.00 Result: A test result of 0.421
passes, because it is less than 1.00.
For the CX/EX White Level test, check the selection box. Then enter
a value for Tolerance ±. The CX/EX White Level test is classified a
failure if the measured white level is outside the range defined by
this percent, applied to the Target Luminance defined on the
Backlight tab. Enter a value ranging from 0 (zero) to 25 (default =
10.00). Tests producing a white level value outside of this
percentage range generate a warning message.
EXAMPLE: Target white level: 600 cd/m
2
Tolerance: ±10% Result: Values outside the range from 540 to 660
(600 ± 60 cd/m
2
) indicate a test failure.
