Failed Hipot Test
If the hipot test detects errors, the analyzer prompts
Failed Hipot Test
. Press
Display/Print
to step through the errors detected. The display will prompt the prob-
lem nets as either
Has Leakage
, or as
Over Current
.
•
Has Leakage
indicates that there is weak insulation between pins or
bare wires that nearly touch. These defects have the potential to become
short circuits. At the most sensitive settings, contamination from finger-
prints or body oils deposited while handling connectors may cause a
cable to fail.
•
Over Current
indicates that the cable has excessive capacitance for the
selected hipot voltage setting or if the resistance of the leak is suffi-
ciently low (approximately 500 Kohms). If the cable has too much
capacitance, try using a lower hipot voltage.
Dielectric Fail:
This indicates that the analyzer detected electrical arcing between nets during the
hipot test. If the analyzer can isolate the nets that are arcing during the test, it will
prompt them in the display. If it cannot isolate the specific nets that are arcing, it will
prompt
Undetermined Net
.
Intermittent
If a cable develops shorts or opens after it first tests as good, the display prompts an
intermittent error. The analyzer emits a steady series of clicks as though the cable
were good.
• Press
Display/Print
to show the error condition that existed when the
intermittent occurred.
• Clear the intermittent by pressing the
Memory
button on the back of the
analyzer.
