Items Calibrated:-

  • Copper Cable Testers
  • Fiber Optic Testers
  • OTDR`s

Calibration Process

Calibration consists of comparing the output of the process instrument being calibrated against the output of a standard instrument of known accuracy, when the same input (measured quantity) is applied to both instruments. During this calibration process, the instrument is tested by repeating the comparison procedure over a range of inputs, in this case reference cables & adaptors and adjustments carried out if necessary.

NOTE: Calibration Date Change on Fluke DTX / DSX Series

It is not possible to change the calibration date within the cable testers, however, we can now supply additional access to software to be able to change the calibration date of your test results exported from Linkware (pdf files) to match the calibration date on the certificates that we provide, your actual test results remain unchanged it is only the calibration date that is changed to match the certificates.

You are provided with an unique code key to access to the URL based software that can be used indefinitely.

We are the only company offering this service, for further information please contact us.


An instrument calibration is said to be `traceable` when the original reference sources for its calibration can be traced back to the National Reference Standards. For practical reasons this will normally be via a chain of calibrations, creating an unbroken hierarchy from the National Reference Standard through a laboratory.

ANSI/NCSL Z540-1-1994 defines traceability as “The property of a result of a measurement whereby it can be related to appropriate standards, generally national or international standards, through an unbroken chain of comparisons”.

We keep all records indefinitely and these can be traced any time by the RMA number which is on the certificates, this RMA number is the returns number issued to customers for traceability of their units whilst in our facility for repair or calibration.

Although we are not ISO approved we work to their standards, the standards state that the calibration certificate must contain at least the following information:

  • The identification of the equipment being calibrated
  • The calibration results obtained
  • The measurement uncertainty
  • Any use limitations on the equipment calibrated
  • The date of the calibration
  • The authority under which the certificate is issued
