The UNI-T UT593 combines insulation resistance, continuity, line and loop impedance, RCD, phase sequence and AC voltage testing in one portable instrument. It is designed for electrical installation inspection, commissioning, fault finding and routine maintenance.

Key Features

  • Insulation resistance testing at selectable 250V, 500V and 1000V test voltages, with measurement ranges up to 1000MΩ.
  • Low-resistance continuity testing with over 200mA test current for checking protective conductors and bonding connections.
  • Line, loop and non-trip loop impedance testing, with prospective fault current measurement up to 26kA.
  • RCD testing at 10mA, 30mA, 100mA, 300mA and 500mA, including trip-time, ramp, phase-angle and countdown test modes.
  • Additional phase sequence and AC voltage testing, supported by a 9999-count backlit display, data storage and automatic power-off.
