30. Glossary
Adapters: Interchangeable devices with connectors that attach the the cable being tested to the tester
Connections: The continuous electrical path between 2 or more points wherein current ows. The path is constructed with
metal parts, such as copper wire, contacts, terminations, splices, and mating contacts of connectors.
Device-Under-Test (DUT): The cable, harness, or other assembly that is being tested by the cable tester.
Dielectric Withstand (DW): The tester applies the required voltage for the determined amount of time and watches for
current ow. Ideally, no current ows and the cable is not harmed.
Fixturing: The test interface or adapter cables that connect the device-under-test to the tester.
Hipot/High Voltage Test: A high voltage or hipot test checks for “good isolation.” This test checks that no current ows
between points where there should be no current.
Intermittent Errors: Errors that occur sporadically or inconsistently.
Intermittents Test: Gives the operator a chance to move and ex the cable, searching for intermittent errors.
Insulation Resistance (IR): The test applies a voltage and measures the current to determine if the resistance of the
insulation is high enough.
Had Leakage error: Occurs because more current than is acceptable leaks between unconnected points.
Learn: The process of the tester scanning a known-good cable to create a test program.
Low Voltage Test: The tester applies a current to the wire and measures the voltage. If the wire is connected correctly,
the test will read low resistance, meaning current is owing through the wire as expected and reaching the required
connections.
Miswire: An unintended connection which is the result of a misplaced contact within a connector.
Net: Two or more interconnected points in a cable or harness.
Open: The intended electrical path contains a gap across which electric current cannot pass.
Overcurrent error: A larger amount of the current is able to ow through the wire than the tester expects.
Short: An unintended connection between 2 or more parts. This failure indicates insucient insulation between metal
conductors which were not intended to be connected.
Test Program: The list of instructions used to test cables and harnesses.
