Uni-T UT528AU Portable Appliance Tester (PAT)
The UNI-T UT528AU Portable Appliance Tester (PAT) is a multifunction electrical safety tester designed for testing the electrical safety of appliances, extension leads, and IEC leads. Configured for Australian and New Zealand electrical standards, the UT528AU performs automatic test sequences after selecting the appropriate Class I, Class II, or cord-testing mode, then displays individual measurements and an overall PASS/FAIL result.
Features:
- Configured for Australian and New Zealand electrical standards.
- Performs automatic test sequences.
- Supports Class I appliance testing.
- Supports Class II appliance testing.
- Supports IEC lead and extension lead testing.
- Measures earth continuity resistance.
- Measures insulation resistance.
- Measures leakage current.
- Performs cord polarity testing.
- Built-in mains socket wiring tester.
