The Uni-T UT593AU is a comprehensive multifunction electrical installation tester specifically engineered for Australian electricians and HVAC contractors. Designed to handle the rigors of the job site, this versatile tool allows you to verify RCD trip time and current, loop/line impedance, continuity, and insulation resistance with a single, reliable device. It is built to meet AS/NZS electrical standards, ensuring your test results are always compliant and ready for sign-off.

Equipped with a 9999-count LCD and an analogue bar, the UT593AU provides clear, stable readings even in poorly lit plant rooms or cramped switchboards. Its robust construction and user-friendly interface make it a staple for anyone needing to perform quick, accurate verification of electrical systems without mucking around with multiple instruments.

Why It Matters

In the fast-paced world of electrical contracting, speed and accuracy are non-negotiable. Using the UT593AU means you can confidently assess fault levels and disconnection times, reducing the risk of call-backs and ensuring every installation meets local safety regulations. Whether you are working on a Sydney fit-out or a dusty industrial shed, this tester provides the peace of mind that your work is safe and verified.

Tradie Pro Tip

When testing RCDs, always run the x½ test first to confirm the device won✓t nuisance trip during standard operation. Then, use both 0 degree and 180 degree phase angles for x1 and x5 tests to capture the most accurate trip time required by Aussie verification standards.
