Intermittent Errors
The 1100H+ looks for intermittent errors in a cable during the
Intermittent Test.
Intermittent
errors include the
same
short and open errors found in the low voltage test, as described in the
previous section.
What’s the difference between Intermittent Errors and Low Voltage Errors?
To be an
Intermittent Error,
the tester must sense that the cable wire pattern:
1. Was good,
2. Then changed to bad,
3. Then changed back to good.
Intermittent Errors are caused by:
Cable defects that show up only when the cable is moved or wiggled during the test.
The same as those described in the previous section for opens and shorts.
High Voltage (Hipot) Errors
Failed hipot errors occur during the high voltage test.
Like other error messages, press
View
& Print Errors,
to see the detailed
error message.
For example, this message for a hipot
failure describes:
1. The type of hipot failure
AND
2. Which net or test point failed.
Note:
The High Voltage error message does
not
show what the error was to, only that it
happened
from the displayed net.
For example, the error message shows
two
hipot errors;
therefore, we assume
these two points were arcing to each
other (NET NC means the error
occurred on an unconnected point in
the connector).
If more than two hipot errors occur,
you cannot assume which points were
leaking or arcing to each other.
