Cirris: 8100 Low Voltage Harness Tester

8100 Wire Harness Tester

Categories: , SKU: CTS-8100


The 8100 low voltage tester is driven by the powerful Easy-Wire® software. It’s compact and flexible to integrate with your production process.

The system is expandable to 100,000 test points​ and capably represents and tests complex wire assemblies, including electrical components. The test system allows operators to view connector images with target pin locations during the assembly process or rework. Its compact size means it is non-intrusive at the workstation, can be mounted on the back of a harness board, or can be distributed with other 8100 units around the device to be tested.

Optional and Expandable Digital IO, OPC UA, and an API allow the tester the flexibility to integrate with factory automation.​


Test Points

Up to 256 test points per base or expansion unit. Expandable up to 100,000 max test points. Expansion units may be distributed up to 200″ (60 m) from the base.

Product Options

8100 Base Unit

8100 Base Unit with 256 test points and one Easy-Wire Software license.

8100 Expansion Unit

Each 8100 Expansion Unit provides 256 additional test points but must be connected to an 8100 test system that has an 8100 Base Unit connected to the operating PC.

8100 Base Unit with Digital IO

Unit configured with an IO card requires one test-point card position, leaving 192 tester points. The Digital IO capability provides 8 outputs and 20 inputs/outputs.

Cirris Server

Provides a network database for all connector definitions and test programs. Strongly recommended to ensure compatibility between all test stations without importing and exporting. Additionally provides a centralized location for backup and test data access.

Advanced Test Instructions

Provide full control over the measurement test voltage and current. Make isolated capacitance and resistance measurements between selected test points.

Cirris Tester Access API

Alternatively control the tester with a third part applications written in LabVIEW, Python, C, C#, C++ and Delphi.

OPC UA Server

Transmit tester status and test information in real time to other information systems or equipment.

8100 Performance Check Kit

Verify calibration with the performance check kit. The certificate of calibration included with a performance check kit is valid for two years.
