When it comes to electrical safety, your Portable Appliance Tester (PAT) is one of the most critical tools in your workflow. Whether you are an independent technician, contractor or managing a team, the accuracy of your tester directly affects every result you produce.

At TESTntel, we’re proud to introduce our new PAT Tester Servicing division, offering professional calibration services designed specifically for technicians and organisations across New Zealand.

Why PAT Tester Calibration Matters

PAT testers are responsible for verifying the safety of electrical equipment under AS/NZS 3760:2022 standards. If your tester itself is not accurate, every result you produce becomes questionable.

Every serviced unit at TESTntel is issued with a formal Calibration Certificate and Verification Tag, including detailed pass/fail data for key tests such as Earth Bond, Insulation Resistance, Leakage and RCD performance.

How Often Should a PAT Tester Be Calibrated?

It is recommended that your appliance tester is re-calibrated every 12 months compliance with AS/NZS 3760:2022.

For technicians who rely on their testers daily, annual calibration is a practical way to avoid unexpected faults and maintain consistent, reliable performance.

What Our PAT Tester Servicing Includes

Our service is designed to cover both compliance and practical field needs.

This may include:

Calibration and verification of tester performance
Full inspection and fault diagnosis
Calibration sticker
Formal calibration certificate

If any issue is identified during calibration, we will pause and contact you before proceeding, ensuring full transparency and control over next steps.

Beyond calibration, our services support better long-term equipment management, including:

Clear service history and documentation
Reduced long-term equipment replacement costs
Improved operational efficiency
A trusted technical support

Some specific models (e.g. Metrel MI 3340, AlphaEE XA, Seaward Primetest 3760DL, Seaward Supernova and Sonel models) may have manufacturer software restrictions that prevent the internal calibration due date from being reset. Where this applies, TESTntel will clearly explain what can be completed, what cannot be digitally changed and how the issued calibration certificate supports compliance records.

If you are unsure whether your unit is supported, feel free to check with us before booking.
