- MICROTEST Wire Cable Harness Tester 8761
One-machine Detection of Electrical Characteristics for Wire Harness/Connectors, including Conductivity, Short/Open Circuits, Voltage Insulation Resistance, Resistance, and Capacitance.
MICROTEST 8761 series Cable Harness Tester employs precise four-wire measurement technology to perform comprehensive electrical characteristic tests on wire harness products, meeting the low resistance level of 1mΩ. The testing capabilities include continuity impedance, open/short circuit, AC/DC safety withstand voltage, IR insulation, and component testing (resistor/capacitor/diode). The testing points can be selected from 64/128/256 options, with a maximum AC withstand voltage output of 1000V and a maximum DC withstand voltage output of 1500V. It supports PC connectivity software and BAR Code scanning, meeting the requirements for automated line testing in wire and connector production.

4-Wire Test
Connect to DUT directly to prevent any deviation.
For measuring low resistance DUT, we recommend to choose 4-wire tester.
The measurement items of 8761/8761NAK 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.
| Conductance | Detect the contact resistance in the cable connector. The conduction resistance is over the standard. |
| 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 |
Put a stabile high voltage on cable to make sure the quality of DUT
- _DC insulation
The result will judge by the rate of insulation resistance. Insulation resistance defect may cause DUT be penetrated or leakage current under high voltage.
- _Arc Test
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.
Insulation resistance between loop is lower than the standard.
The voltage resistance is lower than the standard that cause leakage current.
