Maintenance service

Reliable manufacturer repair support

We repair harness testers that we manufacture and sell. Experienced technicians of harness tester manufacturers will promptly provide high-quality repair services.


Quick response with high technology

Harness testers are widely used in harness, connector, and touch panel shipping tests, harness acceptance tests, maintenance and inspections, and repairs are very important to users. Our goal is to provide repair services that satisfy our customers with our advanced technology.


Repair support models

Please refer to the "Repair and Maintenance Service End Model List" for models that support repair.
The models listed are no longer supported for repair, so we recommend the replacement model.
For special testers and customized products, models that have passed 10 years since the last production (including initial production) (no repeat production for 10 years) will be discontinued.
Please contact us for more information.


Warranty after repair

The warranty period for repaired products is 3 months after delivery. Repairs will be made free of charge only if a failure occurs in the same place as the last repair during this period.
