[Cable harness testing is an essential process]
Cable and harness are indispensable components of electronic devices.
These are manufactured with wires and connectors and are used for power supply and signal communication.

The manufacture is small-quantity, large-variety, and complex.
Therefore, almost all cable and harness are manufactured by hand.
It is difficult to reduce processing errors and defects to zero.
Testing cable and harness is an essential process to determine if electrical standards are met and to prevent defective products.

[Testing with cable harness testers ]
The testing is conventionally conducted with a buzzer tester.
However, it is difficult to confirm the conduction or non-conduction of all pins.
There is also a risk of omissions in testing.

With a cable harness tester, the process can be completed in a short time.
Cable harness testers can achieve quality improvement by performing high-level testing and keeping test records.


[Cable harness testing]
There are five items in cable harness testing.
Wiring testing, Conduction Resistance testing, Momentary Disconnection testing, Dielectric Withstand Testing, Insulation Resistance testing.
Test items are performed according to the test target.

[1.Wiring Testing]
Wiring testing is the most basic of the five.
It determines if the wiring is correct by testing for short, open, miswiring, and extra circuits.
The tester judges the conduction or non-conduction of all testing terminals by the resistance value.
It is necessary to select a tester that covers the number of points to be tested.

[2.Conduction Resistance Testing]
In the conduction resistance testing, the resistance values of all circuits are measured and judged.
If the measured value is out of range, it is judged as a failure.
We have models available with 4-wire low-resistance testing that can precisely measure resistances as low as 0.01Ω.

[3.Momentary DisconnectionTtesting]
Momentary disconnection testing is a test to determine the occurrence of momentary disconnection.
The test is conducted by applying stresses such as shock, vibration, bending, and tension while monitoring the continuity state. Some models are capable of detecting momentary disconnection at the 0.1μsec level.

[4.Dielectric Withstand Testing]
In the dielectric withstand testing, high voltage is applied to determine if there is any discharge phenomenon between the different conductors.
If the current value leaking into different conductors exceeds the specified value, the cable fails the test.
In addition to AC dielectric withstand testing, we also have models that can perform with DC voltage for long cables.

[5. Insulation Resistance Testing]
In Insulation Resistance Testing, high voltage is applied to measure and determine the resistance between different conductors.
By applying to multiple circuits at once, cable harness testers can perform hi-pot testing efficiently.
