Comprehensive Electrical Testing Capabilities

The UNI-T UT593 is designed to perform a full range of electrical installation tests in compliance with international standards such as IEC 61557. It helps professionals verify wiring safety, insulation quality, and circuit protection — all from a single, compact device.

Key testing functions include:

• Insulation Resistance Measurement (up to 1000V test voltage)

• RCD (Residual Current Device) Test – for checking trip time and current

• Loop Impedance Test and Line Impedance Test – for assessing circuit integrity

• Voltage and Frequency Measurement

• Continuity Testing with audible indication

These capabilities make it ideal for testing newly installed circuits, performing safety inspections, or diagnosing faults in existing electrical systems.

High Accuracy and Reliable Performance

The UT593 delivers high accuracy and stability across all measurement functions. It features multiple selectable test voltages for insulation resistance (250V, 500V, and 1000V), ensuring compatibility with different system types and insulation materials.

Its loop and line impedance measurement helps detect excessive wiring resistance that could cause voltage drops or poor performance. The RCD testing mode allows verification of residual current protection devices by measuring their trip time and current at various settings (½, 1×, 5× IΔn), ensuring the safety of both people and equipment.

The meter provides fast, consistent readings, supported by an advanced internal processor that minimizes test time while maximizing accuracy.
