Uni-T UT511 High-Voltage Insulation Resistance Tester

Uni-T UT511 High-Voltage Insulation Resistance Tester

The Uni-T UT511 High-Voltage Insulation Resistance Tester is the entry-level model in the UT510 series, designed for insulation measurements at voltages up to 1000 V and a range up to 10 GΩ. It is ideal for diagnosing electrical installations, motors, or medium-voltage equipment where higher test voltages are not required. The device offers PI and DAR measurements, a memory for 18 results, and a clear 9999-count display with a bar graph, facilitating a quick assessment of insulation condition without the need for additional software.

Suitable for standard measurements

The test voltage range of 100–1000 V makes the UT511 well-suited for daily service and inspection work. In practice, this means convenient testing of installations, cables, or motors without entering the ranges typical of advanced high-voltage testers.

Extended insulation diagnostics

The PI and DAR functions allow for a more accurate assessment of insulation condition over time. This makes it possible not only to detect a fault but also to notice a gradual deterioration of parameters, which is important during periodic inspections.

Clear display and user-friendly operation

The large display with a bar graph provides a quick overview of value changes during measurement. The backlight facilitates work in low-light conditions, and intuitive operation reduces setup time.

Safe field operation

Automatic discharge after measurement and high-voltage warning reduce the risk of working with a charged object. Additional messages regarding out-of-range readings and low battery help prevent erroneous readings.
