Description


MICROTEST 8761NK-512P 512-Pin 4-Wire Cable & Harness Tester, 1 kV DC

The MICROTEST 8761NK-512P is a 512-pin 4-wire cable and wire harness tester with continuity measurement from 1 mΩ to 52 Ω. Separate current and voltage-sense connections reduce the effect of fixture lead resistance when checking low-resistance conductors and contacts. It provides DC Hipot testing up to 1 kV, insulation resistance covering 0.1 MΩ–1.2 GΩ, open/short testing, intermittent-fault detection and resistor, capacitor and diode checks. The 512-point K configuration provides additional connection capacity in a 435 × 270 × 360 mm enclosure. A separate low-resistance scanning function covers 10 mΩ to 52 Ω at 10 mA. Storage for up to 500 test files and RS-232, USB Host, printer and remote interfaces support repeat production work.

Key Features
  • 4-wire measurement with 512 test-point configurations.
  • Continuity resistance from 1 mΩ to 52 Ω, with a 10 mA measurement current.
  • Open/short, intermittent continuity, intermittent open/short, single-side testing and terminal judgement.
  • K enclosure with 16 front connector slots for high connection-count fixtures.
  • Low-resistance scanning from 10 mΩ to 52 Ω at 10 mA.
  • NK: DC Hipot up to 1 kV; NAK: up to 700 V AC and 1 kV DC.
  • Insulation resistance covering 0.1 MΩ–1.2 GΩ.
  • Component checks: resistance 50 mΩ–20 MΩ, capacitance 10 pF–12 µF and diode voltage 0.1–6.8 V.
  • Automatic circuit learning for connection-pattern inspection.
  • Up to 500 stored test files, programmable continuous testing, pin search and self-diagnosis.
  • RS-232, USB Host, Print and Remote interfaces; optional PC Link and production accessories.
Applications
  • Production inspection of cable and wire harness assemblies with up to 512 test points.
  • Low-resistance conductor and contact checks using four-wire fixtures.
  • Electrical inspection of automotive and consumer-electronics harnesses, connectors and flexible flat cables.
  • Detecting intermittent connections during handling or movement of the assembly.
  • Checking resistors, capacitors and diodes incorporated into cable assemblies.
  • Dielectric-strength and insulation testing within the selected model’s ratings.

Product Images

The 8761K configuration provides 512 test points using 4-wire measurement. Its 270 mm-high enclosure accommodates 16 front connector slots.

512 test points for larger cable assemblies

Separate current and voltage-sense connections reduce fixture lead resistance errors. Continuity measurement from 1 mΩ to 52 Ω supports low-resistance cable and connector checks.

Four-wire measurement down to 1 mΩ

Check that intended connections are present and unintended connections are absent. Automatic circuit learning helps establish the wiring pattern for inspection.

Identify open and short circuits

Apply DC Hipot and insulation resistance tests across the series. NA models add AC testing up to 700 V; FA models reach 1 kV AC and 1.5 kV DC. N models provide DC testing only.

Check dielectric strength and insulation

Measure resistors, capacitors and diodes incorporated into cable assemblies. Component ranges include resistance from 50 mΩ to 20 MΩ and capacitance from 10 pF to 12 µF.

Test components within the assembly

RS-232, USB Host, printer and remote interfaces support a production test station. Optional PC Link, networking and remote-control accessories can be selected for the installation.
