TnT-EL Appliance Tester Calibration

Wavecom recommends routine verification every twelve months, and that is the interval most auditors expect to see. If the unit has been dropped, has been through a very heavy testing season, or has given a result you did not believe, bring it forward rather than waiting out the year.

AS/NZS 3760 states that the equipment used to perform the tests it describes should be subject to routine verification at regular intervals, to confirm it is working correctly and its accuracy is maintained. It is the basis on which an auditor asks to see your records.

Yes. The unit is manufactured by Wavecom in Australia and has been distributed badged as the Nesco Electromate. If the label on your tester says either name, it is the same instrument and the same calibration.

Verification compares the unit against reference standards and records what it reads. Calibration includes adjusting it back into tolerance where the unit allows. We do both, and the certificate shows the readings before and after so you can see which happened.

Instrument and serial number, as-found readings, as-left readings, the reference standards used and their traceability, the date, and the recommended next calibration date. It is also stored in your HKCT customer portal.

Yes. We attend premises across Sydney, Melbourne, Brisbane, Perth, Adelaide, Hobart, Gladstone and the Northern Territory. Onsite usually makes sense once you have several testers, since nothing leaves the building and no one is waiting on a return courier.

Most TnT-EL units move through quickly. We confirm the expected turnaround when the job is booked rather than after the unit arrives, so you can plan around it.

We tell you what is wrong and what it costs to fix before doing the work. Worn leads are the most common cause and the cheapest fix. If an older unit has drifted beyond economic repair we will say so rather than quoting work on a tester at the end of its life.

Yes. The TnT+, TnT RCD, TnT ELB, TnT Titan, TnT Titan Lite and the TnP print units all go through the same process, and a mixed fleet can be booked as a single job.

It depends what you are being asked to produce. The TnT-EL has no onboard memory or data logging, and AS/NZS 3760:2022 tightened the expectations around recording test measurements. If you are now being asked for records the unit cannot produce, a model with memory and RCD testing is the answer. Worth raising when you book.
