PAT testers are measurement instruments and it is important to routinely check that
your PAT Tester is measuring correctly.
This process is known as calibration. It is recommended that this should be carried out annually to ensure that your PAT test results are safe and accurate.
Note: The IEE PAT Testing Code of Practice says “The accuracy of a test instrument should be verified and recorded annually or in accordance with the manufacturer’s instructions.” By returning the Tester to us for calibration you comply with this recommendation.
The PAT tester is cleaned and refurbished.
The unit is then calibrated using our calibration equipment. Please note our test results are traceable back to national standards. New calibration labels are applied to the unit.
Our test engineers will automatically upgrade the software on your PAT tester where necessary.
