Section 3: What the Option Settings Mean / Insulation Resistance
1000HN User’s Guide / page 20
mines how effective the insulation on a cable is during a test. The higher the voltage
you set, the higher the insulation resistance the analyzer can detect. Voltage settings
will affect the range of insulation resistance settings available to you.
Warning!!
Do
not subject cable assemblies to voltages higher than they are designed to handle,
because this may damage them. For example, ribbon cable is usually designed to han-
dle up to 300 volts.
Insulation Resistance The available range for each hipot voltage setting is shown in the table below. This
setting selects the minimum resistance between wires that should not be connected.
When you select an Insulation Resistance setting, you are specifying the minimum
resistance that two unconnected nets can have between them, and still be considered
good when the hipot voltage is applied.
This table shows how the Hipot Voltage setting limits what Insulation Resistance
settings are available.
Hipot Duration Range : 10ms, 100ms., 1 second, 2 seconds, 5 seconds, 10 seconds, 30 seconds, 1
minute. This setting determines the length of time voltage will be applied to each
NET during hipot testing. The longer the setting, the more likely the analyzer is to
detect faults which occur over time (intermittents); but testing will take longer.
Important! The system will not perform a hipot test until a cable has passed a con-
ductance test. Once leakage above the set threshold is detected, the high voltage is
switched off.
Apply Hipot To
This setting determines whether the hipot voltage will be applied to all adapter pins
(whether they have connections or not), or only to those adapter pins that are
connected to other pins. The available settings are
ALL ADAPTER PINS
, or
CONNECTIONS ONLY
. The
CONNECTIONS ONLY
setting is generally faster,
since only connected pins will be hipot tested.
Auto Hipot This option lets you choose between automatic and manual hipot testing. When this
option is
ON
, the analyzer will automatically begin a hipot test on a cable as soon as
that cable passes a resistance test. You can repeat the hipot test by pressing the
