Electrical Appliance Testers

Moreover, maintaining the integrity of your mains and having an understanding of how much power your appliances use is also just good practice.

Types of tests that you may need to perform are those related to current leakage and insulation (500v and 250 v). Other applications which testers can be used for include analysing class one and two equipment, extension leads, safety switches and your overall mains power supply.

But no matter what the test is you’re performing, you need to guarantee that your portable electrical appliance testing equipment (also known as PAT testers) are accurate and working reliably in the first place.

To ensure this, you need to have your portable electrical appliance testers calibrated. We advise that you have it done annually, which is typically in accordance with the manufacturer’s instructions.

Exceptional Service Available Australia-Wide

Through our seven locations Australia wide, the team at HK Calibration Technologies Pty. Ltd., (HKCT) provides an exceptional professional calibration service.

We have a quick turnaround time and can offer our calibration service to most electrical appliance testing equipment on the Australian market.

To National standards

Our calibration services are traceable to Australian national standards by way of an unbroken chain of refernce standards calibration. As stated in AS/NZS:3760:2010: "The equipment required to carry out the tests detailed in this Standard (AS/NZS3760) should be subjected to routine verification at regular intervals to ensure it is working correctly and its accuracy is maintained." This procedure is audited by our third party certification body (SAI Global) to the premier ISO 9001-2008 standard.

We can calibrate leading brands such as:

Onside testing Available

We can calibrate your electrical appliance tester onsite or at one of our state of the art workshops in Sydney, Melbourne, Perth, Brisbane, Adelaide, Hobart and Gladstone & Mackay. To find out more about our cost effective Australia wide services phone 1300 309 881 or enquire online.

Frequently Asked Questions

Electrical appliance testing involves a series of safety checks such as earth continuity, insulation resistance, and polarity tests. Using devices like insulation testers, earth loop impedance testers, and RCD testers, technicians systematically verify that appliances are safe to use before issuing a compliance report.

Equipment is calibrated by comparing the device's readings to certified reference standards under controlled conditions. Technicians use precision calibration tools—like multimeters, calibrators, and insulation testers—to adjust measurement accuracy. After adjustments, a calibration certificate is issued to confirm the device meets specified tolerances.

We calibrate a broad range of electrical testing gear, including multimeters, clamp meters, insulation resistance testers, RCD (residual current device) testers, earth loop impedance testers, PAT (portable appliance tester) units, and voltage testers ensuring reliable, traceable accuracy across diverse diagnostic tools.

Regular testing detects potential faults before they cause harm. It ensures appliances meet safety standards, reduces the risk of electrical fires, and helps businesses stay compliant with workplace regulations. Preventive testing also extends the lifespan of equipment and avoids costly downtime.

Testing frequency depends on the environment and appliance type. For example, portable appliances in high-risk areas like workshops may require testing every 3–6 months, while low-risk office equipment may only need annual or bi-annual checks. Industry safety guidelines help determine exact intervals.
