Cirris 4200 Series User Manual
10. High Voltage (Hipot) - 4250 only
High voltage or “hipot” testing is used to nd defects and contaminants that could cause the cable to fail.
WARNING: Read the Safety/Support section of this manual (page 4) before performing high voltage testing. For more
ideas on high voltage safety, visit cirris.com/safety.
10.1 High Voltage Testing
High voltage settings can only be edited when high voltage is turned
ON.
● ON: The tester will perform a high voltage test after a success-
ful low voltage test.
● OFF: The tester will not perform a high voltage test.
● Basic Settings: Adjust the basic high voltage settings you
might nd in your test specications, such as voltage, insula-
tion resistance, and dwell time. Other settings are automati-
cally set accordingly.
● Advanced Settings: Adjust individual settings for the Dielec-
tric Withstand (DW) test and the Insulation Ressitance (IR) Test.
Note: Once Basic Settings or Advanced Settings have been changed, the button will turn green while the other button will
turn blue.
● Options: Adjust other settings having to do with the high voltage test such as selecting which pins will be included
in the test, whether a high-cap shield is present on the cable, and if you want to use high-speed mode.
10.2 Basic Settings
High Voltage: Set the voltage limits required for your cable’s
specications.
Insulation Resistance: Set the resistance limits in order to measure
your cable’s isolation. The measured insulation resistance must be
equal or greater to the insulation resistance setting for the test.
Dwell Time: Set the amount of time the IR value must remain good
to pass the test. The reported resistance value for the IR test is an
average of the measurements taken over this time.
