Certification

Calibration certificates

All lasers, compensators (including sensors) rotary axis calibrators and ballbar systems are delivered with comprehensive calibration certificates.  

The certificate is a valuable document and is proof of the equipment’s performance as tested before delivery (and system performance if part of a system).

Always keep the certificate for reference as it may be required to satisfy your own or your customer’s quality assurance requirements.

Calibration certificates

Each certificate is unique and is identified by a certificate number. It gives details of the specific test results for each unit together in tabular and graphical format (after adjustment and repair if required), and uncertainty of measurement. This enables you to see clearly whether or not the unit meets published specifications or your own requirements.

The certificate also includes

• A description of the calibration process
• Test environment and applicable standards
• Traceability data (artefacts used and calibration details)

The date of testing and the date of printing the certificate are separately noted and the results are signed by a Renishaw authorised person, all in accordance with the requirements of ISO 17025. 

Note that separate laser and sensor certification (and digital communication between units) allows you to interchange components whilst maintaining traceable accuracy for the whole system; something that isn't possible if you have a single "system" calibration.
