The Risk of an Unsupported Tester

Occasionally a part needed to build or repair a Cirris tester becomes unavailable. When that happens, the tester is considered unsupported. Even though Cirris will recommend a replacement tester, some customers choose to continue testing with the unsupported tester. This decision comes with certain risks to the customer.

  • The reason a part becomes unavailable is usually because the part is outdated. Supported testers use current technology for a better testing experience. Unsupported testers use old technology that may not be able to run important features.
  • If an unsupported tester breaks, it cannot be repaired, leaving you in a difficult situation. With supported testers, arrangements can be made to provide a rental unit until the tester is repaired. This is not an option with unsupported testers.
  • Depending on the problem, tech support will not be able to help with an unsupported tester. You can certainly ask, but there may not be a good answer if you are using an unsupported tester.

Although some Cirris customers still use original testers from past decades, we recommend that you upgrade to a supported tester. We want to provide you with the best testing experience and that includes making sure you have the right equipment for the job.
