UNI T Insulation Resistance Tester UT502A is used to measure the insulation resistance of electrical equipment and household appliances. This UT-502A insulation continuity tester is done by measuring the insulation resistance between electrical circuits or between circuits and the ground. This digital megohmmeter can measure insulation resistance, AC Voltage, low resistance, PI (Polarization Index), and DAR (Dielectric Absorption). This cable insulation resistance tester is an ideal tool for ensuring transformers, generators, high voltage motors, power capacitors, power cables, arresters, and other electrical equipment that can operate in a safe and accurate manner.

Features:

• 2000 count LCD display, overload indication, backlight.
• AC voltage measurement, auto power off.
• Auto discharge.
• Continuous measurement mode, red warning light, and buzzer function.
• Continuous low resistance measurement.
• PI and DAR measurement, auto resistivity calculation.
• Low resistance returning to zero function to improve accuracy.
