Description
UT593AU is a comprehensive multifunction electrical installation tester for Aussie sparkies and HVAC contractors who need to verify RCD trip time/current, loop/line impedance, continuity (200 mA), and insulation resistance (250/500/1000 V) on the job. Built for local conditions and meets AS/NZS electrical standards—so your test sheets stack up. Too easy.
Key Features & Trade Benefits
- 9999-count LCD with analogue bar + backlight — quick to read in plant rooms and switchboards; fewer fat-finger errors.
- Insulation resistance 250/500/1000 V — test up to 1000 MΩ with stable readings for cables, motors and boards. Fair dinkum reliable.
- Earth continuity >200 mA — complies with common verification practice; proves bonds without mucking around.
- Loop/Line impedance + PFC/PSC (to 26 kA) — assess fault levels and disconnection times with confidence.
- RCD tests (10/30/100/300/500 mA) — x½, x1, x5 and ramp, with 0°/180° phase angle and countdown mode to catch nuisance trips.
- Auto check & connection status — stop-start workflow that saves minutes per board, not seconds.
- Heavy-duty carry case + full lead set — grab-and-go for site work; keeps the kit tidy in the ute.
Why This Installation Tester Matters
You’re on a Sydney fit-out verifying RCDs and loop impedance before handover. With the UT593AU, you’ll nail trip time at x1 and x5, run a non-trip loop check on sensitive circuits, then store results without second-guessing. That’s fewer call-backs and a cleaner sign-off. For more instruments, see our Electrical Testing collection.
Pro Tip
On RCD testing, run x½ first to confirm no unwanted trip, then x1 and x5. Use both 0° and 180° phase angles to capture the fastest trip time, as required by many site procedures. She’ll be right when your times sit inside spec.
Compatibility & System Info
- Operating voltage (RCD/loop): 195–253 V; line impedance up to 440 V (45–65 Hz).
- RCD currents: 10/30/100/300/500 mA; trip time and ramp tests available.
- Meets AS/NZS electrical standards: suitable for verification workflows aligned to Wiring Rules/verification guidance when used by a competent person.
Local Jobsite Note (AU)
From humid Brisbane risers to dusty industrial sheds, use the 200 mA continuity test to prove bonds and the non-trip loop mode on RCD-protected circuits—no worries.

FAQs
Does UT593AU support non-trip loop testing on RCD-protected circuits?
Yes. Use the non-trip loop impedance mode for 195–253 V circuits to avoid tripping upstream devices while checking Zs.
What RCD tests can I run for compliance docs?
You can run x½, x1, x5 and ramp tests from 10 mA to 500 mA with 0°/180° phase options and a 30 s countdown mode—handy for methodical verification.
Where can I read official guidance on RCD testing and electrical risk management?
See Safe Work Australia’s Model Code of Practice on managing electrical risks; it references RCD testing and record-keeping expectations in AU workplaces.
