The UT-593 is built for electrical installation testing, offering insulation resistance measurement, loop impedance checks with or without RCD tripping, line impedance, protective conductor continuity, trip current, RCD tripping time, AC/DC voltage readings, and phase sequence display. These functions give technicians a single device capable of handling many common on-site procedures with consistent accuracy.

High voltage is required for proper insulation resistance testing, so it’s important to follow all safety instructions in the device manual during use.

Its resistance testing supports 250V, 500V, and 1000V ranges, with measurement capabilities up to 1000 MΩ. Accuracy remains stable across the entire span, while open circuit voltage stays within a controlled tolerance. Small-resistance measurements down to 0.01 Ω provide flexibility for continuity checks, and voltage testing handles both AC and DC up to 440 V.

For installations requiring RCD verification, the UT-593 measures multiple trip currents, trip times, and performs phase sequence tests. Loop and line impedance measurement ranges ensure compatibility with a wide variety of circuits. Automatic range switching, RS‑232, and USB connectivity give you options for convenient data handling.

The meter also includes helpful interface features such as high‑voltage warnings, phase switching during RCD tests, automatic AC/DC detection, and a reset function for low‑resistance work. The backlit LCD and audible alerts make operation intuitive even in challenging environments.

Operating conditions allow use between 0 °C and 40 °C with up to 85% relative humidity. It runs on eight AA batteries, offering a balance of portability and long service life. The meter weighs 1.1 kg and fits comfortably in hand thanks to an ergonomic design.

Its protective casing and lightweight construction make it reliable for field technicians who frequently travel between job sites. The full kit includes a durable carrying case that keeps all accessories organized and ready for deployment.

Additional downloadable files—such as the data sheet and manual—provide detailed technical information when needed.

Whether you're performing installation checks, safety diagnostics, or routine maintenance, this multifunction meter provides steady performance you can trust.
