Instrument Calibration

Ensuring your instruments are performing to specification means you can continue to rely on your test results.

With an instrument calibration performed by Coherent Solutions service engineers you will receive:

  • A full calibration of all instrument specifications
  • A comprehensive inspection to ensure all functions work as expected
  • Firmware, software and documentation updates
  • A Certificate of Calibration which includes detailed performance results

We recommend all Coherent Solutions instruments are calibrated every 12 months. Exceptions: optical switches and passive modules recommended calibration interval is every 18 months.

To request a calibration service, please complete the Calibration Request Form.

To help maintain continuity of your test and measurement system, we offer 3 and 5 year annual calibration plans.

Our calibration offerings enable you to predict costs and plan around your business requirements. They are also a cost-effective way to ensure your test and measurement systems are performing at their best.

Instrument Service/Repair

Sometimes equipment may suffer damage, or its performance might degrade over time, e.g. due to a buildup of dirt or contamination on fiber connectors. In these circumstances you may need to return the instrument for inspection and possible repair.

Notes: Before any repairs begin, you will be provided a full quote including any applicable freight costs. A test setup fee will apply to any returned instrument that, after test, performs to its expected specifications.
