Automobile harness
Most of harnesses are made of copper. Several to dozen thin harness were covered by plastic insulating tube. They are soft and not easy to break. The normal cross-sectional area are 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0. There are all with different load current values for different power devices.
| Specification | Application |
| 0.5 | Dashboard light, side light, door light |
| 0.75 | Plate light |
| 1.0 | Fog light、indicator |
| 1.5 | Head light, horn |
| 2.5-4 | Main power cable、Generator cable |
The measurement items of 8740NAK/8740NK cable or harness tester have (1) Open/Short;(2) Conductance; (3) Components; (4) AC Hipot; (5) DC insulation/ Hipot; (6) Quick conductance (7) Intermittence O/S, and (8) Quick Intermittence open circuit. It supports RS-232, USB Host, Print, Remote interfaces.
Power application PCB/FPC multi points withstanding test.
| Conductance | Detect the contact resistance in the cable connector. The conduction resistance is over the standard. |
| HI pot Test |
Put a stabile high voltage on cable to make sure the quality of DUT
The result will judge by the rate of insulation resistance. Insulation resistance defect may cause DUT be penetrated or leakage current under high voltage.
Some high precision product for automobile and military can’t accept any arc under high voltage.
Inspect the loop contact in the connector fit the request of insulation and voltage.
|
| Open/Short Test |
Make sure the contact of wire work properly. Open: The wire should be contact, but it doesn’t Short: The wire shouldn’t be contacted, but it does |
| Intermittence O/S |
Make sure the cable has intermittent open/short defection |
8740NAK offer result calculation which can show the number of pass/fail and the reason caused.
