Performing a Test

Automatic Analysis

To perform automatic grading, connect the fiber to the GVIS 400-HDP and focus the image. If the fiber needs
cleaning, do so and reconnect the fiber to the GVIS 400-HDP, focus, and press the Analyze button. The GVIS
software performs and reports the analysis by comparing defects to the IEC 61300-3-35 2009 specification and
reports Pass or Fail with the number of defects that caused a failure in each zone.
Defects that are colored in blue were found but are less than the specified size for the zone and are not
considered a failure. Defects colored red are equal to or larger than the specified size and cause a failure. See
IEC 61300-3-35 2009 specification for detailed information.
To show detailed information about a defect, mouse-over the defect so that a pop-up window appears below
the Pass/Fail box in the upper left hand corner. See Figure 19.
To change the specification that is used to determine pass or fail, choose Test Settings tab and choose the
desired specification before performing a test.
