Overview

The UT512E is the 2.5 kV entry to the UT513 family, rated CAT IV 600 V. It tests insulation resistance up to 2.5 TΩ at test voltages to 2500 V — well matched to low- and medium-voltage motors, cables, and switchgear where a full 5 kV output isn't required but a wide, high-resistance range still is.

It includes Polarization Index testing, 10% stepped-voltage profiling, a comparison function, and capacitance measurement, with automatic discharge after each test. Results store 999 sets and transfer over USB, and a 14.8 V 5200 mAh rechargeable pack runs a full field day. It's backed by UNI-T's nearly 40 years of test-meter manufacturing.

UT512E Details

2.5 kV Insulation Testing

Test voltages to 2500 V and a measurement range to 2.5 TΩ cover low- and medium-voltage insulation work — motor windings, cable, and switchgear — without the higher output of the 5 kV models.

PI & Stepped-Voltage Profiling

A timed Polarization Index test flags moisture and aging, and 10% stepped-voltage profiling stresses the dielectric in stages to reveal marginal insulation that a single fixed reading would pass.

Capacitance & Comparison

Built-in capacitance measurement to 2 µF supports cable and winding work, and a comparison function sets a pass/fail threshold for fast, repeatable go/no-go decisions.

Safety & Field Build

Automatic discharge clears stored charge at the end of each test. The CAT IV 600 V rating and a 14.8 V 5200 mAh rechargeable pack make it ready for industrial and utility field use.
