To fully understand MiniScan measurement results, you should be familiar
with the shading of the bar graph, the indications of Pass/Fail status
when limit checking, and the viewing options available in MiniScan mode.
MiniScan Graph Shading
The MiniScan graph is comprised of up to four contrasting shades:
White
The background color of the graph when limit checking is turned off. Also
the background area within limit boundaries when limit checking is enabled.
Gray
The color of each channel's measurement bar when limit checking is turned
off. Also the color of each channel's measurement bar when limit checking
is enabled and the signal level is within the configured boundaries.
Black/White Diagonal Hash Lines
The area above and below the configured limit boundaries (also described
as the area "out of range").
Black
The color of each channel's measurement bar when the signal level is
not within the limit-set range. This occurs when the top of the measurement
bar overlaps the area of black/white diagonal hash lines, indicating measurement
failure in relation to the selected limit set.
Limit Checking Results
When limit checking is enabled in graph view, an overall Pass or Fail symbol
and the name of the selected limit set are displayed above the bar graph.
When limit checking is enabled in table view, channels that fail are indicated
in the column to the left of the channel number, and the direction in
which the measurement is out of range (too high or too low) is indicated
to the right of the level measurement (with an up or down arrow). NOTE:
No Pass/Fail information is available in either view when limit checking
is turned off.
Viewing Options
Several viewing options are available to assist you with data assessment.
